Safety Information
The following general safety precautions must be observed during all
phases of operation of this instrument.
Failure to comply with these precautions or with specific warnings or operating instructions in the product
manuals violates safety standards of
design, manufacture, and intended use
of the instrument. Keysight Technologies assumes no liability for the customer's failure to comply with these
requirements.
General
Do not use this product in any manner not
specified by the manufacturer. The protective features of this product must not be
impaired if it is used in a manner specified in
the operation instructions.
Before Applying Power
Verify that all safety precautions are taken.
Make all connections to the unit before
applying power. Note the external markings
described under “Safety Symbols”.
Ground the Instrument
Keysight chassis’ are provided with a
grounding-type power plug. The
instrument chassis and cover must be
connected to an electrical ground to
minimize shock hazard. The ground pin
must be firmly connected to an electrical ground (safety ground) terminal at
the power outlet. Any interruption of
the protective (grounding) conductor
or disconnection of the protective
earth terminal will cause a potential
shock hazard that could result in personal injury.
Do Not Operate in an Explosive
Atmosphere
Do not operate the module/chassis in
the presence of flammable gases or
fumes.
Do Not Operate Near Flammable
Liquids
Do not operate the module/chassis in
the presence of flammable liquids or
near containers of such liquids.
Cleaning
Clean the outside of the Keysight module/chassis with a soft, lint-free,
slightly dampened cloth. Do not use
detergent or chemical solvents.
iv
Do Not Remove Instrument Cover
Only qualified, service-trained personnel who are aware of the hazards
involved should remove instrument
covers. Always disconnect the power
cable and any external circuits before
removing the instrument cover.
Keep away from live circuits
Operating personnel must not remove
equipment covers or shields. Procedures involving the removal of covers
and shields are for use by servicetrained personnel only. Under certain
conditions, dangerous voltages may
exist even with the equipment
switched off. To avoid dangerous electrical shock, DO NOT perform procedures involving cover or shield removal
unless you are qualified to do so.
DO NOT operate damaged
equipment
Whenever it is possible that the safety
protection features built into this product have been impaired, either through
physical damage, excessive moisture,
or any other reason, REMOVE POWER
and do not use the product until safe
operation can be verified by servicetrained personnel. If necessary, return
the product to a Keysight Technologies
Sales and Service Office for service and
repair to ensure the safety features are
maintained.
DO NOT block the primary
disconnect
The primary disconnect device is the
appliance connector/power cord when
a chassis used by itself, but when
installed into a rack or system the disconnect may be impaired and must be
considered part of the installation.
Do Not Modify the Instrument
Do not install substitute parts or perform any unauthorized modification to
the product. Return the product to a
Keysight Sales and Service Office to
ensure that safety features are maintained.
In Case of Damage
Instruments that appear damaged or
defective should be made inoperative
and secured against unintended operation until they can be repaired by
qualified service personnel
Do NOT block vents and fan exhaust:
To ensure adequate cooling and ventilation, leave a gap of at least 50mm
(2") around vent holes on both sides of
the chassis.
Do NOT operate with empty slots: To
ensure proper cooling and avoid damaging equipment, fill each empty slot
with an AXIe filler panel module.
Do NOT stack free-standing chassis:
Stacked chassis should be rackmounted.
All modules are grounded through the
chassis: During installation, tighten
each module's retaining screws to
secure the module to the chassis and
to make the ground connection.
Operator is responsible to maintain
safe operating conditions. To ensure
safe operating conditions, modules
should not be operated beyond the full
temperature range specified in the
Environmental and physical specification. Exceeding safe operating conditions can result in shorter lifespan,
improper module performance and
user safety issues. When the modules
are in use and operation within the
specified full temperature range is not
maintained, module surface temperatures may exceed safe handling conditions which can cause discomfort or
burns if touched. In the event of a
module exceeding the full temperature
range, always allow the module to cool
before touching or removing modules
from the chassis.

Introduction
AXIe Chassis Description
AXIe Chassis Description
The Keysight M9502A (2-slot) and M9505A (5-slot) AXIe chassis are modular
instrument chassis fully compatible with the AXIe 1.0 specification. They allow
multiple application-specific instrument modules to share a common chassis
frame, power supply, cooling system, PCI Express (PCIe) Gen 2 data bus, Gigabit
LAN hub, local bus for module-to-module signaling, and host PC connections.
Multiple chassis may be interconnected for scalability, in either a multiple
chassis or MultiFrame configuration; see “Using Multiple Chassis” on page 42 for
more information.
The full rack chassis provides (two or five) general purpose peripheral slots that
accept 1U AXIe instrument modules.
Each module slot is supplied with a Gen 2 x4 link (maximum of 2 GB/s data rate
per module) to the chassis primary data ‘fabric’ hub—a x8 PCIe switch and data
bus.
Both chassis include a half-height Embedded System Module (ESM) which
manages chassis functions. The ESM provides all ATCA shelf manager functions,
plus these AXIe extensions:
- provides host PC connectivity (Gen 2 PCIe x8 and/or Ethernet)
- sources timing signals (CLK100, SYNC and FCLK)
- routes STRIG (Star Trigger) to instruments through the backplane
- routes trigger signals through an external parallel trigger bus
- provides backplane PCIe and Ethernet communication between modules
Other than a Power button and instrument status light, all monitoring, control
and communication with the chassis requires a host PC. This can be an
embedded controller such as the Keysight M9536A (a Windows-based PC
specifically designed for use in an AXIe chassis) or remote (a rackmount,
desktop, or laptop PC).
The shared Gen 2 x8 PCIe interface from the ESM to an external host PC provides
up to a 4 GB/s data rate shared among installed modules.
In order for a computer to serve as host PC, its BIOS must support enumeration
of PCIe slots in the AXIe chassis; many computers are not capable of
enumerating a sufficient number of PCIe slots to ensure that slots in an external
chassis are enumerated. Keysight maintains a document listing the integrated,
rack mount, desktop and laptop computers that have been verified to properly
enumerate PCIe devices in the AXIe chassis, at
www.keysight.com/find/axie-chassis.
For general host PC requirements, such as operating system and RAM
requirements, please refer to the M9502A/M9505A AXIe Chassis Startup Guide.

AXIe Embedded System Module (ESM)
AXIe Embedded System Module (ESM)
The ESM is installed in a half-height slot at the base of the chassis. It performs
the following functions:
- tracks inserted modules and manages power requirements
- monitors chassis temperature and controls variable-speed chassis fans
- monitors module sensors and reports component failures to a system log
- acts as a Gigabit Ethernet switch; forwards packets along the backplane
- connects an external host PC to the chassis
- synchronizes timing across all modules through the Keysight Trigger Bus,
using an internal or external clock source

AXIe Embedded System Module (ESM) Option U20 with USB
Introduction
AXIe Embedded System Module (ESM) Option U20 with USB
The Option U20 ESM provides the same features as the standard ESM and adds a
USB 2.0 port*.
The USB port is supported only for specific Keysight AXIe
modules and software. Refer to the documentation for the
supported modules and software for USB use and operating
instructions.
This USB port provides the following features:
- It enables using the AXIe chassis and the supported USB compatible AXIe
modules and software with any host controller that has a USB 2.0 port.
USB
- Either the USB port or the PCIe port may be used -- but not both
simultaneously. To change connectivity between USB and PCIe, power down
the chassis and host PC. Connect either a USB or PCIe cable, but not both.
Power up the system.
- USB provides easy PC connectivity and uses less expensive and longer cables
than PCIe. USB is physically hot pluggable, however you must restart the
software controlling the module(s) when a USB connectivity change is made.
You do not need to reboot the chassis or host PC.
- USB provides control for the chassis and the Keysight Logic Analysis and
Protocol Test Modules but not other AXIe modules. USB-compatible and PCIe
compatible modules cannot be used at the same time. If you are controlling
an AXIe module via USB, you must change cable connections and reboot the
host PC before controlling an AXIe module via PCIe.
STOP!
IMPORTANT: The installation and setup information in this manual is generic.
The USB port is supported only through specific Keysight software
applications and modules such as the Keysight logic and protocol analyzer
software and modules. These AXIe systems that use the USB port may require
a different installation and setup procedure than described in this manual.
Refer to the installation documentation supplied with your AXIe module or
system for detailed installation information.
Some AXIe test system software applications, such as the
Keysight logic and protocol analyzer software and modules,
sets and uses specific trigger lines in the AXIe chassis. Do
not use the AXIe chassis Soft Front Panel (SFP) software or
the AXIe chassis web interface to set or reroute any of the
AXIe chassis trigger lines. Rerouting any of the trigger lines
may cause the application software to not function
correctly.
* The USB port requires AXIe chassis firmware 1.3.37 or later. Refer to M9502A/M9505A User Guide.

Introduction
AXIe Instrument Modules
AXIe Instrument Modules
The chassis slots accept AXIe instrument modules. These may comprise one or
more instruments for signal injection, data acquisition, and measurement. Install
them in any available AXIe slot.
There are two special type of instrument modules which—if used—are most
typically installed in slot 1 (consult the module vendor for specific slot placement
requirements).
- An instrument hub module — a specialty instrument module which also acts
as a hub for a secondary vendor-defined x4 data fabric.
- An integrated controller module — this is a host PC with a form factor and
backplane connections specifically designed for an AXIe chassis. It uses the
chassis backplane for PCIe and LAN connection to the ESM.
The drawing below illustrates the AXIe module’s general layout, backplane
connections and chassis fasteners, viewed from the top.

ESD Precautions
Introduction
ESD Precautions
Keysight’s AXIe chassis and instrument modules are shipped in materials which
prevent static electricity damage. These instruments should only be removed
from the packaging in an anti-static area ensuring that correct anti-static
precautions are taken. Store all modules in anti-static envelopes when not
installed.
Electrostatic discharge (ESD) can damage or destroy electronic components. All
work on electronic assemblies should be performed at a static-safe work station.
The following figure shows an example of a static-safe work station using two
types of ESD protection. Purchase acceptable ESD accessories from your local
supplier.
- Conductive table-mat and wrist-strap
combination.
- Conductive floor-mat and heel-strap
combination.
Both types, when used together, provide
a significant level of ESD protection. Of
the two, only the table-mat and
wrist-strap combination provides
adequate ESD protection when used
alone. To ensure user safety, the
static-safe accessories must provide at
least 1 M of isolation from ground.

front panel switch in the standby (not depressed) position, the chassis is in
STANDBY mode. Although no power is supplied to the ESM and installed modules
when in Standby, the chassis is energized and consumes power. Fans may
operate.
ON With the power cord attached, circuit breaker closed, and the front panel
switch in the ON (depressed) position, the chassis is ON. Power is supplied to the
ESM and installed modules. Fans will operate as dictated by chassis thermal
load.

The chassis and host PC must be powered up and down in the following
sequence. The chassis should be powered up first, which will initiate its built-in
self test. During self test, the chassis STATUS LED will be amber. The STATUS
LED will blink green and then stay green continuously when the ESM is ready.
The ESM then powers up each module slot. The remote host PC should be
turned on only after all installed modules have performed their
initialization—see your module documentation for initialization information. An
embedded controller such as the M9536A handles this sequence automatically.

moduless have performed their initialization. See
your module documentation for initialization
informattion.
If, while the chassis was poweered
down its configuration was changed
down,
in any way, the PC must be resstarted
after Windows comes up (as
indicated by the Windows splash
screen).
For the first-ever connection off the
chassis to the PC,
PC the PC mustt also
be restarted as shown above.
It is recommended that the PC
be shut down before the chassis
is powered down because many
PCs don’t have the capability to
safely remove (eject) PCIeconnected devices. Therefore,
powering-down the chassis first
can disrupt operation of the PC.
In brief, the host PC must be off whenever the chassis is powered up or down.
Note the need to restart the host PC (after Windows starts) if the chassis
configuration has been changed in any way while the PC was turned off.
Some AXIe instrument modules (also known as Blades) take longer to be ready
for enumeration than the PXI link ready requirement of 100ms. Consequently, it is
possible for some controllers (such as the Keysight M9536A Embedded
Controller) to enumerate the chassis before all of the individual modules are
ready and therefore not enumerate them. If you have a situation where Keysight
Connection Expert and/or the Windows Device Manager consistently do not find
specific instrument modules when the chassis powers up, increase the module
initialization time. Refer to the Wait time setting in “ESM PCIe Upstream
Connection Settings” on page 48.
While the power sequencing shown above doesn’t apply to an embedded
controller (because an embedded controller and chassis are powered
simultaneously), an embedded controller must also be restarted (after Windows
starts) if the chassis configuration was changed in any way while the chassis and
embedded controller were turned off.

Keysight M9502A/M9505A AXIe Chassis User Guide
Power-Up and Power-Down
Introduction
To Power Down the Chassis
For routine power-down or to cycle power to the chassis, press the chassis
ON/STANDBY switch. The main chassis fans will gradually drop in speed to off, and
the PSU fans will gradually return to idle speed as the PSU cools. This is normal.
If you are using an embedded controller such as the Keysight M9536A, always
shut down the Windows operating system before pressing the chassis
ON/STANDBY switch.
Also, ensure that the embedded PC never goes into sleep or hibernate mode. It
is possible for the PC to lose its chassis enumeration.
For routine power-down, do not use the circuit breaker to turn the chassis off.
Doing so interrupts power to the power supply fans, which could shorten the
life of the PSU. Use the front panel On/Standby switch to power down the unit,
and allow the PSU fans to return to idle before removing power from the
chassis.
Once the chassis has cooled, you may isolate the chassis from AC power as
needed. This is usually done by opening the circuit breaker.

Planning the Installation
Basic Chassis Verification
The M9502A/M9505A AXIe Chassis Startup Guide, provided in print and on CD
with each chassis, includes a step-by-step procedure to connect the chassis to a
host PC and establish basic LAN communication with the chassis using the
built-in Web Interface. Keysight recommends you follow the Steps in the Startup
Guide before proceeding. You may also obtain the latest Startup Guide at
www.keysight.com/find/axie-chassis.
To verify basic chassis operation, it is not mandatory to install modules, mount
the chassis, or interconnect to other chassis.
Complete Installation
After basic chassis operation is verified, you can complete the installation:
Install Modules Install the instrument modules in the chassis (see page 23). If
you’ll be rackmounting the chassis, it is easiest to remove the bumpers (see
page 30) before installing modules.
Mount the Chassis If required, rackmount the chassis using an available
hardware kit. You will need to remove the bumpers before rackmounting the
chassis. See page 29 for instructions; this section also provides considerations
for benchtop use.
Make MultiFrame or Multiple Chassis Connections You may interconnect
two or more AXIe chassis. For more information, see “Using Multiple Chassis” on
page 42.
Once Chassis Are In Place:
Set Up a Host PC Reconnect the chassis to the host PC (complete
instructions are in the Startup Guide).
IMPORTANT: The installation and setup information in this manual is generic.
Some AXIe modules and systems require a different installation and setup
procedure than described in this manual. Refer to the installation documentation
supplied with your AXIe module and or system for detailed installation
information.
Install Software You should have already installed the chassis device drivers
and Keysight IO Libraries Suite on your host PC. You should now install any
device drivers or Soft Front Panel software required for your installed modules.
See page 34.

Keysight M9502A/M9505A AXIe Chassis User Guide
Installing Modules
Chassis Installation
Verify Operation Verify that the chassis powers up correctly and that Keysight
Connection Expert recognizes the chassis configuration and installed modules
(see page 35).
Installing Modules
The AXIe chassis accept modules conforming to the single slot, 1U AXIe
standard. These may include:
- AXIe instrument or instrument hub* modules
- AXIe embedded controller* module
- AXIe filler panel modules
* If used, a hub or controller module must be installed in slot 1
The insertion and removal procedures are the same for the 2-slot and 5-slot
chassis, and for all module types except filler panels.
Static Electricity—The components and connectors on modules are sensitive to
static electricity. To minimize electrostatic damage, take the necessary
anti-static precautions. Both chassis provide a grounding terminal, to which
you can connect a wrist strap. To locate this terminal, see “M9502A 2-Slot AXIe
Chassis at a Glance” on page 4 and “M9505A 5-Slot AXIe Chassis at a Glance”
on page 6.
Empty Slots—Except for performing initial chassis verification or troubleshooting,
do not operate the chassis with empty slots. Always insert a filler panel module
or instrument module into empty slots. This is especially important for the slots
on either side of an instrument module. This allows proper air flow and cooling,
and provides EMI shielding for the chassis and installed components. Leaving
slots empty can increase fan speed, raise ambient noise, overheat components,
and shut down modules.
ESM—The Embedded System Manager is integral to the operation of the
chassis. Except for troubleshooting purposes, do not remove the ESM.
Hot Swap—AXIe does not explicitly support hot swap for instrument modules.
Keysight recommends fully powering down the chassis before installing or
removing modules
Embedded Controller Module—Manually initiate a graceful shutdown of the
controller operating system and power off the chassis before removing the
module.
The chassis is shipped with filler panel modules in all but Slot 1; you may need to
remove filler panels from covered slots.

Installing Modules
To Remove a Filler Panel Module
1 Power down and unplug the AXIe chassis.
2 Fully loosen the captive retaining screws on both sides of the filler panel.
Ensure you fully loosened the captive module retaining screws before trying to
extract any module. If you attempt to pull the module out by the screws (for
filler panels) or by using the extraction handles (other modules) with these
screws still engaged, damage to the chassis or module could result.
3 Grasp the panel by the two retaining screws, and slide it out of the chassis.
To Install a Module
1 Power down and unplug the AXIe chassis (see “To Power Down the Chassis”
on page 15).
2 Plan slot usage. If you are using an embedded controller module, it must be in
Slot 1. If there are modules that will be removed often, insert them into the
topmost slots.

3 Locate the (left and right) guide rails for each slot. The example below
shows the right side guide rails in the M9505A with all slots empty;
typically one or more will be covered. The rails on the M9502A are
identical, just fewer.
Spring guides center the module’s
PCB at the entry of the guide rail
The illustrations below show the M9502A, but apply to both chassis.
4 Align the module’s circuit board with the guide rails on both ends of the
chassis. If the blade has metal plates covering the board, be sure to insert
the circuit board and not the metal plates into the rails. Slide the board
Keysight M9502A/M9505A AXIe Chassis User Guide
25
Chassis Installation
Installing Modules
gently into the two rails. If the fit is tight, slide the board back out and recheck
alignment.
5 Locate the insertion/extraction handles at each side of the module’s front
panel. Extend the ends of both handles, by pulling them inwards towards each
other; the plastic handle end slides about 1 cm on the metal handle shaft.
Then fully open the handles by pivoting them out towards you until they are
perpendicular to the front panel. The left handle is shown below, from the top
view, correctly extended.
If either handle is misaligned, you will not be able to properly install the
module.
6 Slide the module completely into the chassis. When the module’s backplane
connectors contact the chassis backplane, you will feel resistance and the
26
Keysight M9502A/M9505A AXIe Chassis User Guide

Chassis Installation
two handles will begin to close toward each other. The module’s faceplate will
be about 1 cm from the chassis front panel.
7 Continue nudging the module faceplate gently but firmly with your thumbs,
until the handles are pressed up against the chassis and the module’s front
panel lies flush with the chassis’ front panel. This seats the module firmly in
the chassis backplane. If necessary, gently press inward (toward the chassis)
on the handles to ensure full insertion.
8 Tighten the captive retaining screws at both sides of the module.
Modules are grounded through the chassis. Tighten the module retaining
screws to ensure a proper ground connection.
9 Retract the handle ends by sliding them outward on their metal shafts, away
from each other, toward the chassis edge; this secures them out of the way of
test connections.
10 Repeat steps 4 through 9 for additional modules, as needed. Ensure that each
slot has an instrument or filler panel module installed.
11 Plug in and power up the AXIe chassis. Verify that the chassis fans are
operating and free of obstructions that may restrict airflow.

To Remove a Module
The instructions below apply to all module types. The Embedded System Module
(ESM) has the same extraction handles and retaining screws as instrument
modules. If you should ever have to remove the ESM, follow the instructions for
instrument modules below.
1 Power down and unplug the AXIe chassis (see page 15).
2 Fully loosen the captive retaining screws on both sides of the module.
Ensure you fully loosened the captive module retaining screws before trying to
extract any module. If you attempt to pull the module out by the screws (for
filler panels) or by using the extraction handles (other modules) with these
screws still engaged, damage to the chassis or module could result.
3 For a filler panel module, grasp the panel by the two captive retaining screws,
and slide it out of the chassis.
For all other modules, locate the insertion/extraction handles at each side of
the module’s front panel. Extend the plastic ends of both handles by sliding
them outward on their metal handle shafts, inwards towards each other.
4 Open the handles by pivoting them out towards you, away from the chassis.
Place each thumb at the inside of the handle, forefinger outside the handle,
and rotate the handles with your thumbs. When the handles are
perpendicular with the chassis, stop. The module should now be unseated the
module from the chassis backplane and its faceplate from the chassis front
panel.
Grasp the levers to slide the module out of the chassis.

Mounting the Chassis
Chassis Installation
Mounting the Chassis
Environmental and Power Considerations
Consider your anticipated chassis weight (with modules installed), power and
ventilation requirements, benchtop use and rackmounting options to ensure
safety and optimize access to test and control instrumentation.
Weight The 2-slot chassis weighs 7.7 kg (17 lbs), including ESM but with no
other modules installed. With two instrument modules, it can weigh 15.7 kg (35
lbs).
The 5-slot chassis weighs 13.3 kg (29 lbs) with ESM, and can weigh 33.3 kg (73
lbs) fully loaded. It is typically used rackmounted, but can also be used on the
bench, with proper support and ventilation.
AC Input The chassis will operate on 100-120VAC or 200-240VAC, with input
frequency from 50-60 Hz. Maximum input power consumption is 800 VA for the
M9502A, 1350 VA for the M9505A.
.
Avoid overload ing an electrical circuit. Ensure your power supply matches the
AC Input requirements listed above.
In case you need to power down the chassis in an emergency, make sure that
you have clear and quick access to the primary d isconnect. If the chassis is
rackmounted, this primary d isconnect can be a power system on the rack or
the circuit breaker on the chassis.
Ventilation The chassis is designed to dissipate 200W per instrument slot.
Depending on load, the chassis and power supply fans may exhaust significant
heat. Whether used on the benchtop or rackmounted, operate in a well
ventilated environment and allow 2” (5 cm) clearance around both sides of the
chassis.
Do not block the vent holes on the chassis. This overheats and damages components. Leave a gap of
at least 2” (50mm) around all vent holes and fan exhaust areas.
Rackmounting the Chassis
An optional rack mount kit is available from Keysight for each chassis. The kits
include mounting instructions.

Mounting the Chassis
Installed Carry Handles and Bumpers
Both the 2-slot and 5-slot chassis are shipped with carry handles and bumpers
installed for portability and desktop use. For rackmounting, the carry handles
and bumpers must first be removed. Tool needed:
- #2 Phillips driver for M9502A
- #1 and #2 Phillips drivers for M9505A
Save all screws, bumpers and carry handles. Reinstall them if you remove the
chassis from the rack to make it portable or for desktop use or if you ever need to
ship the chassis.
If you have been using the chassis with modules and bumpers installed, you
should remove all modules (including the ESM) before removing the bumpers.
This will make handling the chassis easier and reduce chances of damaging
modules. See “To Remove a Module” on page 28.
On both the M9502A and M9505A chassis, do not attempt to install the carry
handles without the front and rear bumpers. Do not install handle screws
without handle and bumpers installed. Handle screws are too long without the
other components installed and could result in damage to the chassis. If you
remove the chassis from a rack, you should reinstall both the front and rear
bumpers and the carry handles
To Remove the Carry Handle and Bumpers from the M9502A
1 The 2-slot chassis has a single carry handle, which must be removed before
the plastic bumpers. Remove the two #2 Phillips round head screws securing
the handle.

Reinstalling the Bumpers and Carry Handles
If you remove the chassis from the rack to make it portable or for desktop use or
if you ever need to ship the chassis, reinstall the front and rear bumpers and
carry handles. Reverse the previous procedures to install the bumpers and
handles.
A thread-lock screw must be used to secure the handles to the chassis. A new
handle screw kit (M9502-80011) is available for use with both chassis. The screws
are now 14mm long. Tighten the handle screws to 25kgf.cm (21.8 in-lbs).
On both the M9502A and M9505A chassis, do not attempt to install the carry
handles without the front and rear bumpers. Do not install handle screws
without handle and bumpers installed. Handle screws are too long without the
other components installed and could result in damage to the chassis. If you

Setting Up a Host PC
Setting Up a Host PC
Following the M9502A/M9505A AXIe Chassis Startup Guide, you should have
selected a host PC, made physical connection to the chassis, and communicated
with the chassis using its Web Interface. You may have then disconnected the
host PC from the chassis in order to install modules or mount the chassis.
Re-establish that connection, per the Startup Guide.
If you find that your AXIe chassis driver is no longer able to connect, check your
host controller’s Network Adapter settings to make certain that the related NIC
card has not been disabled.
Do not enable the Microsoft Windows sleep mode on the host PC. The PC may
not have proper chassis enumeration when it wakes up and unpredictable
operation may result.
To Install Module Soft Front Panel and Device Drivers
Each installed module typically requires device drivers and control software. You
need not install them to verify basic chassis operation, but would logically install
them on the host PC at this time. For Keysight instrument modules, load each
module’s Software and Product Information CD into the optical drive of your PC
and follow the prompts. For others, consult the module provider for software
requirements and instructions.

Verifying Operation with Modules Installed
In the M9502A/M9505A AXIe Chassis Startup Guide, you should have verified
basic power-on operation of the AXIe chassis and communication with the host
PC. Subsequently, in this chapter you have installed instrument modules and
perhaps rackmounted the chassis. Then you have reconnected the host PC, and
loaded chassis and module software drivers. Reverify that Connection Expert
communicates with the chassis and installed modules.
The LAN connection to the ESM provides communication to the chassis only -chassis firmware updates, web interface to monitor/control the chassis, etc. It
does not provide communication with individual AXIe modules. Use PCIe to
control AXIe modules.
- Power up the chassis (solid green status light on the ESM).
- Reboot the host PC. This allows the host PC’s BIOS to recognize the PCIe
devices in the chassis.
- You may need to run the appropriate Add Hardware process in Windows for
the host PC’s operating system to correctly recognize and enumerate
modules on the PCIe bus.
- Establish chassis communication with Keysight Connection Expert.
- Keysight Connection Expert should recognize installed modules, and they
should be listed on the chassis Web Interface Module Configuration Page.
- After driver installation is complete, restart your PC. The Ethernet Controller
Found New Hard ware Dialog should no longer appear.

Using the M9536A Embedded Controller LAN Ports
Using the M9536A Embedded Controller LAN Ports
If you installed a Keysight M9536A Embedded Controller in the Keysight AXIe
chassis (M9502A or M9505A), there are a total of three LAN ports accessible on
the front panels -- two on the M9536A controller and one on the Embedded
System Module (ESM). Windows Device Manager shows a total of five (5)
individual Network Interface Cards (NICs); one is not used and one connects to
the chassis backplane.
Changing the LAN port connection or removing the LAN cable, may cause
Keysight Connection Expert to lose track of LAN-enabled instruments. Reboot
the AXIe chassis to restore the complete list of LAN-enabled instruments. Read
the following for details.

Keysight M9502A/M9505A AXIe Chassis User Guide
Using the M9536A Embedded Controller LAN Ports
Chassis Installation
This section provides overall guidance on selecting and using the M9536A LAN
ports. The controller uses the Keysight IO Libraries configuration file to keep
track of all instrument connections. Any change to LAN connections after
running Connection Expert (adding, removing, or changing LAN cable
connections) may cause a change in LAN address and therefore cause
Connection Expert to lose track of instruments. If your application programs rely
on a specific IP address, these programs may cease to operate if you change LAN
cable connections.
Changes to the ESM PCIe or LAN connection are only detected as the ESM is
powered up. Perform the following steps when you change either of these two
connections:
1 Within Keysight Connection Expert, delete the LAN interfaces (right click on
the interface then select Delete). This causes Connection Expert to forget all
instrument history.
2 Shut down Windows on the M9536A Embedded Controller.
3 After Windows shuts down, power down the AXIe chassis using the chassis
power button.
4 Make the desired cabling change to the ESM PCIe and/or LAN connections.
5 Power up the AXIe chassis using the chassis power button.
6 Run Keysight Connection Expert and verify that the LAN interfaces are
operating correctly and that Connection Expert finds the AXIe chassis.
With Keysight IO Libraries 16.2 (and later versions) Keysight Connection Expert
should automatically identify the AXIe chassis. With Keysight IO Libraries version
16.1, you may need to start Connection Expert, then power down the controller
and chassis and reboot them in order for Connection Expert to identify the AXIe
chassis.
Recommendations
As a general rule, connect a network LAN cable to the ESM’s LAN port and
connect LXI instruments to the M9536A’s LAN ports. While other configurations
are viable, this configuration provides the fastest and most consistent reporting
in Keysight Connection Expert. Refer to Figure 3.
- Where you have the network and instruments connected when the chassis
and controller first power on determines how quickly Keysight Connection
Expert locates network instruments. If necessary, shut down the controller
and chassis and reboot.
- If you move a LAN cable while chassis power is applied, Connection Expert
may not find all of the instruments available on the network.
Keysight M9502A/M9505A AXIe Chassis User Guide
37
Chassis Installation
Using the M9536A Embedded Controller LAN Ports
For example, if the LAN cable is connected to the ESM when power is first
applied to the chassis and subsequently moved to one of the two LAN ports
on the controller (while the chassis is still powered on), Connection Expert
may only find the M9536A controller and AXIe modules installed in the
chassis. Shut down the controller and chassis and reboot to restore
Connection Expert’s ability to locate other network instruments.
- Connect external LAN-enabled instruments (LXI instruments) to the M9536A
controller LAN ports. This allows Keysight Connection Expert to automatically
find the instruments. These instruments will have a local LAN IP address or
private network range.
LXI instruments may be connected to the ESM’s LAN port but Connection
Expert may not automatically find them when these instruments are not
located on the same LAN subnet range. However, instruments may be added
manually using Connection Expert’s Add Address feature.
- If you are using an external LAN router or switch, cycling power on the chassis
may cause the IP address of the chassis ESM and controller to change.
Therefore you may want to set a static IP address. Refer to your particular
network device’s documentation for information on setting static IP
addresses.
With the Keysight M9536A Embedded Controller installed in the AXIe chassis,
the x8 PCIe connection on the ESM module is disabled. However, the PCIe
cable detect mechanism may reset the hardware when attaching a PCIe
cable. This hardware reset may change the IP address.

Using Multiple Chassis
Using Multiple Chassis
There are several possible ways to configure multiple M9502A 2-Slot and
M9505A 5-Slot AXIe chassis systems. You can also combine AXIe and PXIe
chassis (such as the M9018A PXIe chassis) into multiple chassis configurations.
These multiple chassis configurations are controlled by a single host controller.
The host controller can be either a PXIe Embedded Controller (such as the
Keysight M9036A) or a desktop or rack-mounted computer. For detailed
configuration and installation information, refer to Keysight's Multiple PXIe and
AXIe Chassis Configuration tool. This tool is available on the M9502A/M9505A
Product information CD and on line at:
or
www.keysight.com/find/M9502A
www.keysight.com/find/M9505A
How does a multiple chassis system differ from a MultiFrame system?
In both multiple chassis and MultiFrame systems, all chassis are controlled by a
single controller. The differences between the two system types are:
– In a multiple chassis system, the time base and triggering for each chassis
operates independently from the other chassis. You can use this type of
configuration to increase the number of chassis/modules that do not require a
common time base or cross triggering between chassis. For more information,
refer to Keysight's Multiple PXIe and AXIe Chassis Configuration tool. This tool
is available on the M9018A Product information CD and on line at:
www.keysight.com/find/pxie-multichassis.
– MultiFrame is a Keysight feature by which multiple instruments in two or more
chassis are interconnected to appear as one integral instrument to the user. In
a MultiFrame system, special cabling connects the time base and triggering
of the master chassis to all daisy-chained slave chassis. These cables extend
trigger and timing features to instruments not connected to the master
chassis’s backplane. You can use the MultiFrame configuration to increase the
number of measurement modules utilizing a common time base or cross
triggering. Refer to “MultiFrame Operation” on page 89 for more information.

Use the PCIe connection to control individual AXIe modules.
Launching the Web Interface
The M9502A/M9505A Startup Guide provides detailed instructions for
connecting to the chassis using Keysight Connection Expert and launching the
Chassis Web Interface. Following those instructions, launch the Web Interface.
If you have problems launching the chassis Web interface, check your browser’s
proxy settings. When Keysight Connection Expert launches a Web interface for a
chassis, it hands off the http://<address> to the browser or dedicated web
application. Therefore, it should not use a proxy.

Initial releases of the AXIe chassis will have IP configuration set to Automatic; the
IP Address, Subnet Mask and Default Gateway are set automatically and cannot

When you make a LAN connection between host PC and chassis ESM, and then
power-on the chassis, the following process happens:
1 The chassis, as client, seeks a Dynamic Host Configuration Protocol (DHCP)
server to set the IP configuration.
2 If you connected the chassis and PC to a corporate LAN, the network will
provide the DHCP addresses.
3 If you made a direct LAN connection (physical LAN or implicit LAN connection
through PCIe), the chassis reverts to link-local addressing.
If you are having difficulty ‘finding’ a specific AXIe chassis on a network, you
can search by the mDns Instrument Name, which includes the unique chassis
serial number. This number is located at the rear of the chassis.

ESM PCIe Upstream Connection Settings
The section for the ESM PCIe Upstream Connection displays the current PCIe
configuration (called the Active Configuration) and allows you to change the
configuration if necessary.
You should seldom need to change the PCIe Upstream Configuration. Leave it
set to Auto for the ESM to select the appropriate configuration.
New Configuration
The New Configuration field allows you to designate a PCIe Upstream
Connection or designate an enumeration wait time. As a general rule, you should
not need to reconfigure these; you should leave the PCIe Upstream Configuration
in Auto mode.
If you do select a new PCIe Configuration and/or enumeration wait time, you
must click the Apply New PCIe Settings button to save the changes as the new
default. The changes take effect after cycling power on the chassis. To restore
the factory default setting, click the Restore Factory Defaul t button.
PCIe Upstream Configuration:
The possible PCIe Upstream Connections are:
- Auto: The ESM automatically determines the upstream connection port. This is
the default setting.
- PCIe Front Panel: The PCIe upstream connection port is the ESM PCIe
connector.
- USB Front Panel: The PCIe upstream connection port is the USB PCIe
connector. This option is available only if the Option U20 USB ESM is
installed. See “AXIe Embedded System Module (ESM) Option U20 with USB”
on page 9
- Slot 1 (Instrument Hub): An embedded controller (such as the Keysight M9536A)
can act as a PCIe root complex when installed in slot 1 of the chassis. This is
also known as the “Instrument Hub.”
Depending on your chassis configuration (ESM, embedded controller, etc.) some
of the upstream connections may not appear in the pull-down menu.
Wait Time: You should not need to change the enumeration wait time.
However, some AXIe instrument modules (also known as Blades) take longer to
be ready for enumeration than the PXI link ready requirement of 100ms.
Consequently, it is possible for some controllers (such as the Keysight M9536A
Embedded Controller) to enumerate the chassis before all of the individual
modules are ready and therefore not enumerate them. If you have a situation
where Keysight Connection Expert and/or the Windows Device Manager
consistently do not find specific instrument modules when the chassis powers
up, increase the wait time (valid range is 0 to 60 seconds).

E-Keying
Scrolling down the Module Configuration page displays the E-Keying Activity
information. E-Keying (short for Electronic Keying) is a process in which
compatible matches over links between different modules are identified and
enabled to be used. For more information on E-Keying refer to “Electronic Keying
(E-Keying)” on page 92.
In general, you do not need to understand how E-Keying works. The E-Keying
process is handled by the chassis shelf manager. The following two figures
illustrate the Module E-Keying Activity display in the Module Configuration Page.
In the following segment, note that modules in Slots 3 and 4 (column 1 “From
Slot” and column 2 “To Slot”) have an Enabled status and use the AXIe Local Bus
(62 pair Local Bus). This simply states that the Shelf Manager has given the two
modules permission to communicate directly (E-Keying) over the AXIe backplane
local bus. Also note that both modules are enabled to use the AXIe Timing STRIG
link and the PCI Express fabric.

The Crosspoint Switch provides the flexibility of routing many signal events from
the backplane, flags or external trigger to different destinations. You can choose
to enable and assign the input source for any or all signal destinations
(trigger/timing resources to be output from the ESM). You can also source a
logical 0 or 1 to drive any output for test purposes.
Multiple outputs may be driven from the same input, but each output can have
only one input assigned. The default input for all outputs is “Static 0”, which
assigns a logic 0.
These trigger bus inputs and outputs are covered in detail in “Triggering”
beginning on page 78.
Making Trigger Routing Changes
The Trigger Routing page provides several buttons at the bottom of the form,
which allow you to apply, save, and restore trigger bus States, complete sets of
trigger bus configuration settings. These States are stored in non-volatile RAM
(NVRAM); settings do not change when you cycle power to the chassis.
Trigger bus settings displayed in the Trigger Routing page form are not activated
until you apply them.
Active State: Each time you load or refresh the Trigger Routing page, it shows
the Active State (of the trigger bus).
- The displayed form allows you to make and display configuration changes,
but they are not made Active until you specifically apply them.
- If you click the Apply Changes button, the displayed settings will be made
Active (become the Active State).
- If you do not want to apply the displayed changes, do not click Apply
Changes. You can click Clear Form to clear all trigger bus assignments on the
form.
- If you want to restore the Active State, click the Discard and Refresh button.
Default State: The chassis will store a custom set of default settings, called the
Default State.
- If you click the Save as Default button, the displayed settings will be made
Active and be saved as the new Default State.
- You can always restore the form to the Default State by clicking the Restore

Default State will be made Active.
Factory Default State: You can always restore the form to the factory default, by
clicking the Restore Factory Default button. Then, if you click the Apply Changes

Chassis Health Page
This page has three sections: Sensors, Fan Control and Chassis Firmware
Upgrade. Sensor monitoring is explained in detail in “Shelf Management
Functions” on page 68. To update the chassis firmware, see “Updating the
Chassis Firmware” on page 110.
Configure Fan Control
The minimum chassis fan speed is approximately 2200 RPM; the maximum fan
speed is approximately 6000 RPM. Using a range of 35 to 100 (percentage of
maximum), you can manually set the minimum speed you want the fans to
operate at — 35 means the minimum fan speed of approximately 2200 RPM and
100 is the maximum fan speed of approximately 6000 RPM. Each increment is
approximately 58 RPM.
Do not attempt to set the fan speed below 35. Earlier chassis firmware versions (see
AXIe Chassis Version Information below), used fan speed numbers from 8 to 15,
with 8 representing the minimum fan speed and 15 representing the maximum
fan speed. For backwards compatibility, these numbers are now reserved.
If you have an existing application program using IVI or LabVIEW drivers to set
the minimum fan speed using the old 8 to 15 range, your program will continue
to work normally with the new AXIe chassis firmware; 8 now corresponds to the
new 35 (minimum fan speed) and 15 corresponds to the new 100 (or maximum
fan speed).
The new firmware revision returns fan speed as 35 to 100. If your application
program reads the current fan speed and expects a value between 8 and 15, your
program may error. Please adjust your application appropriately.
Regardless of where you set the minimum fan speed, if the temperature inside
the AXIe chassis rises, the fans speed increases to provide additional cooling.
The resolution of the Current Fan Level, as shown on the Chassis Health interface
page, is an approximation of the fan speed.
The Configure Fan Control section of the Chassis Health Page has the following 5
fields:
Fan Status The shelf manager continuously monitors chassis fan speed,
looking for indication that one or more fans are not turning. Normal fan status
represents a fan speed of at least 2200 RPM (or higher when required by
instrumentation load). Below that speed, the shelf manager reports an alarm
condition for that fan, it attempts to increase fan speed and continues to
monitor. Failure of one fan will not result in interruption of power to installed
modules.
54
Keysight M9502A/M9505A AXIe Chassis User Guide
Chassis Health Page
Navigating the Web Interface
Cooling Status The shelf manager continuously monitors reported module
temperatures, looking for indication that one or more modules is outside its
optimal temperature range. This range is specified by the module vendor, as are
the thresholds for alarm conditions. Typically only high temperatures generate
an alarm, although it is possible for a vendor to specify low temperature alarm
levels as well.
In the event of a high temperature alarm from any module, the shelf manager
responds by increasing chassis fan speed and continuing to monitor. If the Upper
Non-Recoverable threshold is reached, the shelf manager requests the module
to power down to its inactive state. Because this level is set by the module
vendor, it may not indicate that the module has failed, only that continued
operation is inadvisable until the module cools.
Current Speed Level This is the level the fans are currently operating and is
controlled by the Shelf Manager. It increases from a set minimum as needed to
adjust for changes in chassis temperature. The range is from 35 to 100, where 35
is the slowest speed level and 100 is the highest speed level. The Current Speed
Level indicates an approximate percentage of maximum fan RPM. Therefore, a
level of 40 indicates the fans are operating at approximately 40% of maximum
RPM, and 100 indicates the fans are operating at 100% of maximum RPM. Note,
the default/reset value is 40.
Dynamic Minimum Fan Level This is the minimum fan level the shelf manager
algorithm sets as it actively monitors the overall system temperature and
temperature threshold events received from instrument modules. Over time, the
algorithm adjusts this level towards the user-specified minimum fan level
provided the cooling status remains at Normal.
Adjust Current Speed Level and Dynamic Minimum Fan Level This user
adjustable parameter actually sets both values. This level is kept in non-volatile
RAM until you change it; cycling power to the chassis does not change the
minimum fan level. Adjust the minimum fan level by entering a value in the field,
or clicking the up/down arrows, and then clicking the Apply button.
Note that you can individually set the Current Speed Level and the Dynamic
Minimum Fan Level using ICI controls. The Web UI (and the Soft Front Panel)
binds these two together. Setting the Current Speed Level is always temporary
because the Dynamic Minimum Fan Level algorithm continuously adjusts the fan
speed towards a dynamic minimum when cooling conditions permit. For
example, consider a situation where the chassis and installed modules require a
fan speed of 50 to maintain proper cooling. If you attempt to manually set the
Current Fan Speed to a lower value (40 for example) the algorithm overrides the
setting and maintains the fan speed to provide adequate cooling. Conversely, if
you manually set the fan speed to a higher value (65 for example), the algorithm
sets that fan speed and does not change it unless additional cooling becomes
required.

55
Navigating the Web Interface
Chassis Health Page
Of course, since the actual cooling requirements for the chassis and modules
may continuously change, that actual fan Current Speed Level and the Dynamic
Minimum Fan Speed will also change over time.
Example of Chassis Fan Speed
The following graph illustrates how the chassis fan speed operates. For
simplicity, only one temperature event is shown; in reality, temperature events
may be happening frequently causing the fan Current Speed Level to change and
the Dynamic Minimum Fan Speed to gradually change.
Assume at the beginning, the chassis is reporting a Nominal cooling status. The
Dynamic Minimum Fan Level is approximately the same as the fan Current Speed
Level. When one (or more) temperature sensors reports that a temperature has
increased above its Nominal range and is now above its Upper Non-Critical
threshold, a Minor Alert occurs on the cooling status. At this point, the chassis
fan Current Speed Level begins ramping up to provide additional cooling. Note
that the change is not instantaneous.
When the temperature sensors report that the temperature has dropped back
into the Nominal range (because of hysteresis it is actually a few degrees below
the Upper Non-Critical threshold), the chassis fan Current Speed Level begins to
gradually slow down, compensating for the reduced heat load.
56
Keysight M9502A/M9505A AXIe Chassis User Guide
Chassis Health Page
Navigating the Web Interface
During this entire time, the Dynamic Minimum Fan Level algorithm is
recalculating to provide a new minimum fan speed. As additional temperature
events occur, and the Current Fan Level changes, the Dynamic Minimum Fan
Level algorithm recalculates the minimum fan speed required to ensure optimal
cooling in the chassis.

This chapter provides an overview of the AXIe chassis soft front panel (SFP). The
SFP provides the same functionality as the Web Interface. While the Web
Interface runs in a browser window and accesses the web server built into the
chassis, the SFP is an executable which runs on a PC and communicates to the
chassis using the IVI drivers. The SFP is installed automatically when the chassis
software is installed.

The SFP help system can be launched from the Start menu as well.
For detailed information on the features and functionality of the SFP, see the SFP

IMPORTANT: If your chassis is connected to the host PC via a LAN connection,
and Keysight Connection Expert has discovered the chassis as a LAN device, then
the Soft Front Panel software will also find the chassis.
However, if you connected the chassis to the host PC via PCIe cable, you must
manually add the chassis to the LAN device tree. This is true, even if Keysight
Connection Expert has found the chassis and listed it under the PXI device tree.
To add the chassis as a LAN device, select the LAN tree, then select Add
Instrument. The chassis must be added as Socket protocol (typically port 5025).

TCP/IP over PCIe: Communication over
PCIe to the Intel NIC (and downstream
devices such as the LAN Switch,
devices,
Switch Gb
slot interfaces and the Shelf Manager)
uses TCP/IP protocol. Therefore, the
AXIe chassis, when accessed over PCIe,
will be displayed as a LAN device in
Connection Expert as shown
above. PCIe modules, however, will be
displayed under PXIO and will be able to
use the full bandwidth of the PCIe
interface.
3. The PCIe Switch internal buffering allows the chassis to communicate to the host PC at 4 GB/s, and simultaneously communicate at 2 GB/s to each of
two x4 module slots. Factoring in certain overheads, nominal data rates of 1.85 GB/s per slot can be achieved.
2. PCIe Generation ((“Gen”)) 1 peak speed is 2.5 Gb/s per lane. PCIe Gen 2 peak speed is 5.0 Gb/s per lane. Takingg into account encodingg and other overhead,
typical Gen 2 performances in MB/s and GB/s are as follows for x1, x4 and x8: x1: 500 MB/s
x4: 2 GB/s
x8: 4 GB/s
B. While the Intel NIC allows the host PC to use the PCIe interface to access the LAN Switch (and the devices connected to the LAN Switch), the
reverse does not apply -- the PC cannot use the LAN interface and the Intel NIC to access the slot PCIe x4 interfaces..
A. If the chassis PCIe interface is connected and the chassis LAN interface isn’t connected, the Intel NIC provides a means for the PC to access the LAN
Switch – this provides PC access to the Shelf Manager as well as access to the Gb Ethernet connections to each slot.

Shelf Management Functions
All AXIe chassis provide these ATCA shelf management functions:
- Monitor and control chassis fan speed
- Monitor chassis backplane temperature
- Monitor module health, as provided by the module vendor (may include
voltages and temperatures, fuse status, alarms and alarm setpoints)
- Automatically and safely shutdown power upon a fan tray or power supply
unit (PSU) failure
You may monitor chassis behavior and make fan settings as explained below
using the chassis Web Interface, on the Chassis Heal th page.
Shelf management is implemented in the ESM firmware. You may upgrade
firmware through the base interface (LAN) connection.
To Monitor Fans:
You can check the individual chassis fan speeds, fan levels, and status. The fan
speeds are listed under the Chassis header in the Sensors section of the Chassis
Health page.

Shelf Management Functions
Features and Functions
Under Fan Control, you can monitor Fan Status, Cooling Status, Present Fan Level,
and Minimum Fan Level. These are explained in order below.
Fan Status: The shelf manager continuously monitors chassis fan speed,
looking for possible indication that one or more fans are not turning. Nominal fan
status represents a fan speed of approximately 2,000 RPM, higher when required
by instrumentation load. Below that range, the shelf manager will report an
alarm condition for that fan, attempt to increase fan speed and continue to
monitor. Failure of one fan will not result in interruption of power to installed
modules. The fan status conditions are listed below.
Fan Status
Fan Speed (RPM)
Shel f Manager Response
Nominal
2,000 or higher
Continue monitoring fan speed
Lower Non-Critical
Increase fan speed one step and continue monitoring
Lower Critical
Increase fan speed to maximum and continue monitoring
Lower Non-Recoverable
This usually indicates a fan has stopped turning; increase
fan speed to maximum and continue monitoring
Cooling Status: The shelf manager continuously monitors reported module
temperatures, looking for indication that one or more modules is outside its
optimal temperature range. This range is specified by the module vendor, as are
the thresholds for alarm conditions. Typically only high temperatures generate
an alarm, although it is possible for a vendor to specify low temperature alarm
levels as well.
In the event of a high temperature alarm from any module, the shelf manager will
respond by increasing chassis fan speed and continuing to monitor. If the Upper
Non-Recoverable level is reached, the shelf manager will shut down power to
that module. As this level is set by the module vendor, it may not indicate that
the module has failed, only that continued operation is inadvisable until the
module cools.

Current Speed Level
This is the level the fans are currently operating at and is controlled by the Shelf
Manager. It increases from a set minimum as needed to adjust for changes in
chassis temperature. The range is from 35 to 100, where 35 is the slowest speed
level and 100 is the highest speed level. The speed level indicates an
approximate percentage of maximum fan RPM. Therefore, a level of 40 indicates
the fans are operating at 40% of maximum RPM, and 100 indicates the fans are
operating at 100% of maximum RPM.
Dynamic Minimum Fan Level
This is the minimum fan level the shelf manager algorithm sets as it actively
monitors the overall system temperature and temperature threshold events
received from instrument modules. Over time, the algorithm adjusts this level
towards the user-specified minimum fan level provided the cooling status
remains at normal.
Adjust Current Speed Level and Dynamic Minimum Fan Level
This is a user adjustable parameter allowing you to specify a minimum fan speed
level. This level is kept in non-volatile RAM until you change it; cycling power to
the chassis does not change the minimum fan level. Adjust the minimum fan
level by entering a value, or clicking the up/down arrows and clicking the Apply
button.
You cannot monitor the PSU fans.
To Control Fan Speed:
You can set the minimum fan level, over a range from 35 to 100 as a percentage
of maximum fan speed, by setting that level in the Adjust Current Speed Level
and Dynamic Minimum Fan Level field and clicking the Apply button. This
specifies the minimum level at which you want the chassis fans to run. The Shelf
Manager will increase fan speed from that minimum—for all (three or six) chassis
fans—if required by an alarm condition (low fan speed or high module
temperature).
If the minimum fan speed is changed using the Web Interface, the newly-set
value will become the chassis power-on default value. This is unlike other
parameters set using the Web Interface, which do not persist through a power
cycle. For more detailed information on controlling the fans using the Web
Interface, refer to “Configure Fan Control” on page 54.
The power supply (PSU) fans are controlled automatically, you cannot override
them.

Data Channels Explained
The AXIe chassis provides three paths for communication and data transfer to
and from installed modules:
- Gigabit (Gb) Ethernet
- PCIe
- Fabric 2 (optional, requires instrument hub module)

Gb Ethernet:
This is a star-distributed 1 Gb Ethernet:
- From the LAN switch in the ESM—the base channel hub—to each slot.
- From the LAN switch in the ESM to the RJ45 front panel LAN connection;
10/100/1000BASE-TX.
PCIe:
This is the high speed primary data path:
- From the PCIe switch in the ESM—the fabric 1 hub—four lanes to each
instrument slot through the backplane defined as PCIe x4.
- From the PCIe switch in the ESM to the PCIe x8 front panel connection.
Fabric 2: Fabric 2, if implemented, provides a high speed secondary data path
through the backplane:
- From an instrument hub module in slot 1—the fabric 2 hub—four lanes to each
instrument slot through the backplane; protocol is vendor-defined.
- Fabric 2 data does not pass through the ESM; you must make external
connections to the instrument hub to use fabric 2 data
Keysight M9502A/M9505A AXIe Chassis User Guide
73
Features and Functions
PCIe and LAN Switching (data transfer)
Implementing Fabric 2
To use fabric 2, the secondary data path (four channels) through the chassis
backplane, you must:
- Install in slot 1 an AXIe instrument hub module designed to implement the
fabric 2 star. Access to these backplane signals must be controlled by the
instrument hub module.
- Use a remote host PC. With an instrument hub module, you cannot
simultaneously use an embedded controller, which must be installed in slot 1.
Maximizing Data Upload Speeds
The maximum data bandwidth to each slot is dictated by the x4 connection.
You will typically achieve higher PCIe data throughput to a remote (desktop or
rackmount) host PC than to an embedded controller.
- Using a high speed rackmount or desktop PC and a x8 cable, the primary data
fabric utilizes a x8 connection between the ESM and the host PC. The ESM’s
PCIe switch can achieve Gen2 upload speeds when transferring data to the
host from multiple modules simultaneously.
- If an embedded controller is installed in the chassis, that x8 connection is
disabled; the controller uses its slot 1 backplane x4 link to the PCIe switch.
- By using both an instrument hub module and a fast remote host PC with dual
x8 cable adapters, you could potentially move two x8 fabric channels to the
host at Gen 2 speeds (if the instrument hub outputs PCIe x8).
PCIe, LAN or Both?
You can establish communication between the chassis and host PC over either a
LAN or a PCIe connection. In practice, the choice is usually driven by the
interface(s) on your modules. For example, if you have a module with a x4 PCIe
interface, you’ll want to establish a PCIe connection to the chassis.
PCIe Connection Only You may connect the ESM to the host PC using only a
PCIe cable. This allows both the base (LAN) channel and fabric 1 data channels.
Base channel communication between PC, ESM and any LAN capable installed
instruments are made through the PCIe connection. A PCIe to LAN switch in the
ESM manages the base channel communication to the slots; it is seen as a
network interface device by Windows Device Manager.
LAN Connection Only You may connect ESM to host PC using only a LAN
cable. You will have base channel communication only and significantly less data
throughput that when using PCIe.
Hybrid Operation: You may connect both LAN and PCIe cables from ESM to
host PC. This provides the most operational flexibility and some data throughput
advantages over using only PCIe.

Chassis Synchronization and Triggering
Features and Functions
Chassis Synchronization and Triggering
The Keysight AXIe chassis provides a rich set of signaling (triggering and timing)
options. These allow you to achieve time-aligned operation of multiple
instruments installed in a single chassis or MultiFrame (interconnected AXIe
chassis system).
MultiFrame operation is described in “MultiFrame Operation” on page 89. For
this chapter, ‘instruments in the chassis’ includes all instrument modules in the
single chassis or MultiFrame. If you are using only a single chassis, the
MultiFrame references are inapplicable.
An example of time aligned operation would be starting and stopping some
aspect of a test running on multiple instruments in the chassis. The time
alignment of these operations can be:
- Synchronous: A single event (trigger signal or sync signal), initiated by an
external trigger, flag, or other signal transition, triggers one or more
instruments simultaneously.
- Asynchronous: Instruments operate independently, with their resulting data
to be time-aligned post-collection in your analysis software. This requires the
data to be referenced to a common clock source.
Moreover, there is capability to group instruments and perform such operations
on several independent groups simultaneously. For example, instrument group A
can be triggered from a 100MHz clock and instrument group B can receive an
external trigger from an event transition in the test environment, while receiving
the same clock signal to synchronize the two groups.
Although the triggering and timing options can be inter-operated, it is easiest to
understand them using distinct Clock Bus and Trigger Bus diagrams, each
providing ESM front panel and backplane signal connections.
Some AXIe test system software applications, such as the Keysight AXIe Based
Logic Analyzer Software and modules, sets and uses specific trigger lines in the
AXIe chassis. Do not use the AXIe chassis Soft Front Panel (SFP) software or the
AXIe chassis web interface to set or reroute any of the AXIe chassis trigger lines.
Rerouting any of the trigger lines may cause the application software to not
function correctly.

Available Clocks
Clock Outputs The Embedded System Module (ESM) generates a 100 MHz
instrument clock signal from its clock bus. This signal is:
- Star distributed to all instrument slots as CLK100
- Provided to the ESM’s front panel SMA connector CLOCK OUT, as a 10 MHz
external reference clock (3.3V CMOS, 50W)
- Distributed to additional chassis as MULTIFRAME OUTPUT CLK100
A separate 100 MHz distributed PCIe fabric reference clock (FCLK) is provided
from the ESM to all instrument slots.
Clock Sources There are three possible sources for the clock bus in a given
chassis. Clock detection logic is automatic, and the input source is chosen in the
following priority order, depending on which external inputs are sensed:
1 An external reference clock (MULTIFRAME INPUT CLK100) from the lower
chassis connector
2 A 10 MHz external reference clock (CLOCK IN) applied at the ESM’s front panel
SMA connector
If you choose the external 10 MHz reference clock, it must be present at the front
panel SMA connector when the chassis is powered on. If you attach the cable
after power is applied, you must cycle power on the chassis.

Features and Functions
Selecting a Clock Bus Source
By default, the clock bus is driven by the local 100 MHz clock oscillator. You can
also drive the clock bus from an external reference clock supplied by CLOCK IN
or the MultiFrame Cable.
To use CLOCK IN: You can connect a 10 MHz external reference clock source
to drive the clock bus on any given chassis.
1 Provide a clock source at that chassis’s front panel SMA connector. The
chassis will recognize a signal with these characteristics:
– AC coupled, -5V to +5V input
– 250 mV minimum swing
– frequency 10 MHz ±5%
2 The chassis will automatically select CLOCK IN if sensed. When a chassis
senses both CLOCK IN and MULTIFRAME INPUT CLK100, MULTIFRAME
INPUT CLK100 has priority.
If you choose the external 10 MHz reference clock, it must be present at the front
panel SMA connector when the chassis is powered on. If you attach the cable
after power is applied, you must cycle power on the chassis.
To use MultiFrame INPUT CLK100: In a MultiFrame system, the CLK100
signal sourced from the master chassis drives the clock buses for all slave
chassis.
1 The CLK100 signal is provided from the master to each slave chassis’s
MULTIFRAME INPUT (lower chassis) connector.
2 Each slave chassis will automatically select MULTIFRAME INPUT CLK100 as
its clock source if sensed.
Using the Clocks
To use CLK100: Regardless of source, the clock bus output CLK100 can be
accessed by AXIe instruments via the backplane or MultiFrame connection.
1 AXIe modules installed in a given chassis may access CLK100 via the
backplane.
2 If the module is in a slave chassis in a MultiFrame, its clock source is
MULTIFRAME INPUT CLK100 from the Master chassis.
To use CLOCK OUT: You can extend the clock bus output to external
instruments. These are instruments which cannot access CLK100 from that
chassis, either via the backplane or MultiFrame connection. They may be
external to the AXIe chassis or chassis system.

Interface’s Chassis Health page.
Triggering
This section introduces the AXIe chassis’s trigger bus resources and some of the
many ways you may use them. Any AXIe instrument can be triggered:
- internally, based on its own automation or signals from DUT connected
directly to it
- through an externally applied trigger.
- through the chassis backplane,
The AXIe chassis allows you to trigger instruments—singly, in groups, or all
instruments in the chassis—from different signal sources.

Trigger Resources
The primary AXIe trigger resource is the Crosspoint Switch. It allows any trigger
input to be connected to any trigger output.
Trigger Inputs There are many inputs to the Crosspoint Switch. Any input can
be connected to one or more trigger outputs. The inputs include:
- An external trigger (TRIGGER IN) applied at the ESM’s front panel SMA
connector
- Any of the 12 TRIG signals. As these lines are bidirectional, any AXIe module
can source a trigger via the backplane using them. E-keying is used to
manage traffic on the parallel trigger bus.
- Any of the (two to five) STRIG signals. As these lines are bidirectional, any AXIe
module can source a trigger via the backplane using them.
- Any of the four event Flag signals (MULTIFRAME INPUT Flags 1 through 4) from
the lower chassis connector
- A MultiFrame SYNC signal (MULTIFRAME INPUT SYNC) from the lower chassis
connector
- A MultiFrame RUN Signal from the lower or upper chassis connector

Chassis Synchronization and Triggering
To use a STRIG line as an output:
1 Using the chassis Web Interface, on the Trigger Routing page, check an
Output Enable box to enable any individual slot AXIe Star Trigger line as an
output signal.
2 From the Input Signal drop down list, select an input signal for each
output-enabled AXIe Star Trigger output(s).
In the example shown above, STRIG output is enabled for slots 1 through 3,
and will simultaneously trigger these three STRIG lines when an input signal is
received from any instrument on the TRIG 0 bus.
SYNC
The SYNC and CLK100 signals are a Low Voltage Differential Signaling (LVDS)
star trigger and a star clock. SYNC provides an LVDS trigger signal, output at the
next rising edge of CLK100 after the source trigger is received. The SYNC and
CLK100 lines use identical fan out buffers and are trace length matched to 0.25”
to operate as a pair, with the following characteristics:
– Point-to-point between the ESM (logical slot 1) and instrument slots
(physical slots 1 through n)
– Slot terminated with 100W differential

Use When: For truly synchronous applications, SYNC allows you to trigger
multiple instruments both simultaneously and in sync with the reference clock. It
can also be used as a general asynchronous star trigger output line.
To use SYNC as a trigger output:
1 Using the chassis Web Interface, on the Trigger Routing page, note that
SYNC is always output-enabled, as it is not bidirectional.
2 From the Input Signal drop down list, select an input signal for the SYNC
output.
In the above example, SYNC will be driven high synchronously on the next
rising edge of CLK100 after an external SMA trigger input signal is received.
To drive the line asynchronously, uncheck the Sync routed through crosspoint
box; the external trigger will drive SYNC directly.

TRIGGER OUT
The TRIGGER OUT signal (also known as SMA TRIGGER OUT) is available on
the ESM front panel TRIGGER OUT SMA connector with the following
characteristics:
– 3.3V CMOS drive, 100 mV minimum swing
– 50W output termination
Use When: TRIGGER OUT allows you to extend the trigger bus to instruments
outside the chassis system or which require an external input.
To use SMA TRIGGER OUT as an Output Signal:
1 Connect a cable from the chassis SMA TRIGGER OUT connector to the
instrument you wish to trigger.
2 Using the chassis Web Interface, on the Trigger Routing page, check the
Output Enable box to enable the SMA TRIGGER OUT signal as an output
signal.
3 From the Input Signal drop down list, select an input signal to connect to the
output-enabled SMA TRIGGER OUT output signal.
4 Under Conditions, you can select whether or not an 80-160 ns pulse is
generated (always on the rising edge of the signal) and whether the signal is
inverted just prior to the SMA TRIGGER OUT connector. The default is no pulse
(“None”) and Passthrough (no inversion).
In the above example, the SMA TRIGGER OUT output signal is enabled and it
will output an inverted signal when a STRIG signal is received from slot 1.
MultiFrame Flags
Four BLVDS flags are provided on the MultiFrame cables. These flags can be
distributed among any applications in a MultiFrame chassis that use
asynchronous flagging.
A flag is an asynchronous pulse, which any instrument in any chassis can
generate in response to a signal transition or program command.
86
Keysight M9502A/M9505A AXIe Chassis User Guide
Chassis Synchronization and Triggering
Features and Functions
Asynchronous flagging is accomplished by sending a flag and having the rest of
the system act in a pre-configured way when it receives the flag. Any flag can be
set or cleared (by assigning a static 1 or 0) or sourced, using the Web Interface.
The Flag lines are bidirectional. Any chassis can enable any of the four Flag lines
as a trigger bus destination or specify a Flag as a trigger bus source; the
MultiFrame logic will only allow one source per Flag in the MultiFrame.
Use When: The MultiFrame Flags provide for module to module signaling
between modules in different chassis.
To use a MultiFrame Flag as an output signal:
1 As you can see below, there are no Output Enable check boxes; the
MultiFrame output signals are always enabled.
2 From the Input Signal drop down list, select the input signal for each
MultiFrame Flag output signal.
In the above example, Flag 1 will output a trigger when an input signal is
received from an instrument on the TRIG 0 bus. Flag 2 will output a trigger when
an input signal is received from an instrument on the TRIG 1 bus.
Separately, you will need to program other chassis how to respond to a received
MultiFrame flag.
MultiFrame SYNC
A SYNC line is provided on the MultiFrame cables. This can be used to
synchronously trigger any AXIe instruments in the MultiFrame.
To use MultiFrame SYNC as a Trigger Output
A SYNC signal output from the master chassis in the MultiFrame will be passed
to the other chassis over the MultiFrame cable, as MultiFrame Sync.

MultiFrame Operation
Features and Functions
MultiFrame Operation
MultiFrame is a Keysight feature by which multiple measurement instruments in
two or more chassis can be interconnected to appear as one integral instrument
to the user. It includes hardware, software, and cabling specifications.
In practice, the potential combinations of instruments which can share
synchronization and triggering are numerous, and there is no practical limit on
the number of chassis which you may interconnect. This section introduces basic
MultiFrame connection and features, based on a simple MultiFrame of three
M9505A chassis.
MultiFrame operation is a Keysight feature, not an AXIe specification. Cables may
be hot plugged. MultiFrame operation is different from multiple chassis
operation; see “How does a multiple chassis system differ from a MultiFrame
system?” on page 42 for more information.
Use When: Use MultiFrame to increase the number of measurement modules
which utilize a common time base or cross triggering to achieve correlation. The
MultiFrame cables extend trigger and timing features to instruments not
connected to the master chassis’s backplane.
Shared Features
All chassis (therefore all installed instruments) in the MultiFrame can share:
Clock Source A common 100 MHz clock is sourced from the master chassis.
The time offset for clock signals to traverse the cable and signal path between
each pair of chassis is about 35 ns. The MultiFrame design calibrates this out,
within about 600 ps of error.
Cross Synchronization A common SYNC signal is sourced from the master
chassis. The time offset for SYNC to traverse the cable and signal path between
each pair of chassis is about 35 ns. The MultiFrame design calibrates this out,
within about 600 ps of error.
Cross Triggering Any instrument in the MultiFrame can source or receive a
trigger, using any of the four Flag signals carried between chassis using the
MultiFrame cables.
MultiFrame cables (such as the Y1223A and 1224A) can be hot plugged; that is,
you do not need to cycle chassis power when connecting multiple chassis. The
slave chassis detects the presence of the MultiFrame cable and automatically
switches its clock source to the master chassis’ clock output from the MultiFrame
cable.

Features and Functions
LVDS Local Bus
LVDS Local Bus
The M9502A and M9505A chassis backplane provides a local bus with 62
differential signaling pairs between each pair of adjacent instrument physical
slots. This bus is the Low Voltage Differential Signaling or LVDS bus.
Availability of these signal lines to any module will depend on vendor
implementation of the Zone 2 connectors and related commands to manage
signaling on the local bus. See “Interconnection” on page 90 for a look at these
connectors.
The chassis provides these local bus pairs on Zone 2 backplane connectors
P20-P24. Most instrument modules will load connector P20 to access the trigger
and timing bus, and will load connector J23 in order to utilize the AXIe base and
data fabrics. Connector J23 provides the first 22 local bus pairs from backplane
to module.
Modules designed to take maximum advantage of the AXIe local bus will load
additional connectors (P24, P21) and expand the local bus up to 42 or 62 signals
to each adjacent module slot. If P24 (or P24 and P21) are loaded on your
module, likely the vendor is utilizing the local bus.
Check with the module vendor for any instrument in your AXIe chassis to
determine if it utilizes the AXIe local bus and what functionality that feature
provides you.
Electronic Keying (E-Keying)
Electronic keying is one of several capabilities AXIe inherits from the
AdvancedTCA architecture. Like ATCA, AXIe promotes a fabric independent (also
known as fabric-agnostic) backplane with respect to local bus connectivity.
Each module plugged into a chassis may provide various communication
protocols and hardware signaling that connect to pins on the backplane that link
adjacent modules together. In general, the backplane itself does not provide
internal buffering, so a link connection between two adjacent modules is simply
a wired connection, either configured point to point or tied together on a
common bus. This allows different modules in the system to establish their own
link protocols provided a connection path exists.
This flexibility frees the chassis configuration from dictating signal levels and
protocols involved with any particular link. However, this flexibility presents a
challenge: how to know whether the endpoints of a link are compatible or not.
If you have modules in your system that are E-Keying compatible, refer to the
documentation provided with your modules for detailed installation information.
92
Keysight M9502A/M9505A AXIe Chassis User Guide
LVDS Local Bus
Features and Functions
E-Keying is a process in which compatible matches over links between different
modules are identified and enabled to be used. The E-Keying process is handled
by the chassis shelf manager. Each module in the chassis runs a Intelligent
Platform Manager Controller (IPMC). These IPMCs interface with the shelf
manager and each other using the Intelligent Platform Management Bus (IPMB).
IPMB is basically a side channel protocol built on top of I2C that connects all
modules in a chassis together. See the figure below.
The shelf manager has two primary roles:
- Manage the inventory and infrastructure of a chassis by communicating with
IPMCs in the chassis:
– Power requirements of the modules and managing the power module
– Chassis cooling control of the fan module.
– Individual Field Replaceable Unit (FRU)* inventory located in non-volatile
memory that tracks ATCA and AXIe attributes from each module
– E-Keying interconnection resources among modules:
– Point-to-point (P2P) connections for base, fabric, and update channel
interfaces. P2P connections are predominately what AXIe is concerned
with.
– Bussed resources for clock and metallic test bus (in ATCA).
- External connectivity to a system manager, using an IPMI connection over
Ethernet using a RMCP protocol.
* A field replaceable unit is a part that may be removed from a system and exchanged with another part or
returned to a factory for service Examples of FRUs may be a module card in a chassis slot, a fan tray, a power
supply, and the chassis frame.
Keysight M9502A/M9505A AXIe Chassis User Guide
93
Features and Functions
LVDS Local Bus
E-Keying Process
When the chassis powers on, the first step the shelf manager does in
point-to-point (P2P) E-Keying is read the backplane P2P connectivity records
from the chassis modules. These connectivity records specify the P2P
interconnections the backplane routes between specific slots and specific
channels on each slot.
Next, for each board loaded in the chassis, the shelf manager reads each board's
Field Replaceable Unit (FRU) table for the P2P connections that board makes to
the backplane. The shelf manager builds up a connection inventory of all the
potential links a particular board can implement. This list is later used to examine
the potential logical links each board has to other boards. Each potential link end
has a link descriptor that identifies the following information:
- P2P interface on the backplane and a channel number within that interface
- The ports on a given channel that are involved with this link. This may include
sets of differential signal pairs.
- Finally, the link type which identifies the specification entity, such as PICMG
3.x, AXIe 1.0, or other specification that fully describes the link classification.
The link type may also be an OEM-defined value using a 128-bit Globally
Universal Identifier (GUID); each card may support up to 15 different GUIDs.
The shelf manager goes through the backplane connection possibilities,
identifying each end of a P2P connection and searches for a compatible link
descriptors. If a pair of ends match, such as both ends are PCIe Express x4, then
the shelf manager issues a “Set Port State (enable)” command to each board for
that link. For the matches that are not found, the shelf manager issues a “Set
Port State (disable)” command to ensure that incompatible link connections are
kept off.
As a final note, the shelf manager is truly agnostic about specific details of a link
protocol. This permits new protocols to be added without modification to the
chassis.
For additional information on E-Keying, refer to the AdvancedTCA specification
(http://www.picmg.org) and the AXIe specification
(http://www.axiestandard.org).

Module Types
The AXIe chassis provide a wealth of options for high speed, low voltage
differential (LVDS signaling. Whether you can develop individual instrument
modules or modular instrumentation sets, communication between modules
may travel across the backplane.
Depending on your application, you have the flexibility create a variety of module
types.
- Instrument Module: An instrument module can go in any slot and will typically
use the AXIe trigger bus resources. It will not typically use the local bus unless
it is part of an instrumentation set.
- Instrumentation Sets: AXIe provides the opportunity for you to create
scalable, modular measurement and test systems which can occupy two or
more chassis slots.
– If you create a two-module instrumentation set intended to occupy
adjacent slots, you can utilize up to 62 LVDS backplane local bus lines.
This set would function in both the 2-slot and 5-slot chassis, and could be
designed to function in any two adjacent slots of the M9505A. Refer to
“LVDS Local Bus” on page 92 and “Electronic Keying (E-Keying)” on
page 92.
– You can also create instrumentation sets with up to five AXIe modules, and
may implement backplane features and specify module placement as
required.
– Your multiple module instrumentation set can include an instrument hub
module installed in slot 1. That hub may use AXIe trigger bus features,
communicate between adjacent modules using the local bus, and provide
the hub for a secondary x4 backplane data fabric to slots 2 through 5.

ATCA and AXIe Requirements
Overview
The Keysight AXIe (ATCA eXtensions for Instrumentation) chassis backplanes
used in the M9502A and M9505A comply with the AXIe 1.0 Base Architecture
Specification. AXIe 1.0 is based on AdvancedTCA® (ATCA) architecture,
expanded with several eXtensions, all of which will remain electrically
compatible with standard ATCA blades. These modifications provide timing,
triggering, local bus signaling and data transport features.
Keysight provides this chapter as a quick backplane reference for developers of
AXIe instrument and instrument hub modules. It gives a brief explanation of how
the M9502A and M9505A chassis implement AXIe features, and provides signal
connection pin assignments for module backplane connectors.
This summary of AXIe requirements is not intended to replace the applicable module
design standards, which specify mechanical, electrical, and logical interfaces
between module and chassis. AXIe modules must comply with:
- AXIe 1.0 Base Architecture Specification, available at
http://www.axiestandard.org
- AdvancedTCA® PICMG 3.0® Specification, available at
http://www.picmg.org
Most ATCA modules should be able to work in an AXIe environment. Conversely,
developers should design AXIe modules to be compatible in an ATCA
environment.
ATCA Requirements and Exceptions for AXIe 1.0
Mechanical
modules.
AXIe modules must meet all ATCA mechanical requirements for
Exception: AXIe 1.0 chassis do not accommodate rear transition modules
(RTM).
Hard ware Platform (shelf) Management AXIe modules must incorporate the
ATCA hardware platform management features.
Exceptions:
– AXIe uses an intelligent platform bus (IPMB) for platform management
communication between the intelligent FRUs (for example: shelf manager,
module IPMC) in a chassis. This IPMB conforms to the ATCA requirements
for IPMB-0, but with no IPMB redundancy.
– AXIe modules are not required to support the complete hot swap
capabilities of ATCA. However, the module’s FRUs are required to support
all of the operational states required for ATCA front boards.
Keysight M9502A/M9505A AXIe Chassis User Guide
97
For Module Developers
ATCA and AXIe Requirements
– AXIe modules are not required to have the handle switches that sense the
module’s insertion and impending removal from the chassis nor the blue
hot-swap LEDs.
– AXIe modules do not implement ATCA electronic keying, metallic test bus,
and ringing bus.
Power Distribution Dual power supplies are provided to each slot. AXIe
Modules may use either or both supply feeds, and must be able to operate over a
range from –53VDC to –45VDC.
Data Transport AXIe modules must comply with all ATCA requirements for
Zone 2 base and fabric interfaces.
Exceptions:
– AXIe modules only implement a single base interface channel (LAN
channel 1).
– AXIe modules may connect to data fabric channel 1 or channel 2, or both.
– Data fabric channel 1, if used by the AXIe module, must implement a PCIe
connection, operated from the supplied 100MHz reference clock (FCLK).
– Data fabric channel 2, if used by the AXIe module, may implement
proprietary protocols.
– AXIe modules may connect to any of the CLK100, SYNC or STRIG signal
pairs, any of the 12 AXIe TRIG pairs, and any number of available pairs on
either or both local bus ports.
Synchronization Clock AXIe backplanes maintain the bused topology of most
Synchronization Clock signals, and devices implement the same MLVDS
signaling levels as ATCA.
Exceptions:
– AXIe architecture expands the use of the ATCA Synchronization Clock
Interface. The signals and connector pin assignments for AXIe modules
differ from ATCA.
No Update Channel Interface
Exception:
– The AXIe architecture does not implement the ATCA Update Channel
Interface. AXIe backplanes implement a single bused MLVDS topology for
the signals connecting to those Zone 2 connector contacts, and devices
implement different signaling schemes as defined in the AXIe specification.
AXIe modules must implement electronic keying appropriate to prevent
incompatible connections between AXIe and ATCA devices installed in
either system environment.

ATCA and AXIe Requirements
For Module Developers
AXIe Extensions to AdvancedTCA®
AXIe expands the ATCA specification with several eXtensions, Zone 2
customizations which include:
- The AXIe timing interface, providing for specific clock distribution and
signaling between the ESM and instrument slots 1 through 5. This
interface includes timing resources SYNC, CLK100, and STRIG. See
“Chassis Synchronization and Triggering” on page 75 for a complete
functional description of these timing resources.
- A 12 pair MLVDS trigger bus, TRIG[0,11], bused across all slots (the ESM
slot and instrument slots 1 through 5). See “Triggering” on page 78.
- A 62 pair local bus for signaling between adjacent instrument slots. See
“LVDS Local Bus” on page 92.
- The data transport fabric, a dual star x4 PCIe gen2 interface:
– Channel 1 connects the ESM slot in a star configuration to provide an
x4 link to each instrument slot
– Channel 2 star connects slot 1—the instrument hub slot—in a star
configuration to provide an x4 link to instrument slots 2 through 5
– Uses a distributed PCIe fabric reference clock (FCLK) driven from the
ESM
See “LVDS Local Bus” on page 92.
- AXIe chassis implement an extended set of electronic keying records to
assure consistent use of AXIe-defined backplane fabrics and resources.
In the AXIe chassis, the ESM acts as logical slot 1 for base fabric signaling
(LAN) and channel 1 data fabric signaling (PCIe) signaling in addition to shelf
management.
An AXIe instrument hub module is an instrument module that may optionally
serve as a hub for vendor-defined protocols using the data fabric channel 2
star. An instrument hub module must be installed in slot 1 (logical slot 2),
while other AXIe modules can be installed in any slot.

Chassis Backplane Connections
Zone 2 Connector Layout
The Zone 2 connectors provide pins for up to 200 differential signaling pairs per
slot (40 pairs per connector), although most slots and many modules will not
feature all these connectors.
Zone 2 provides the signal connections for the data transport fabric and AXIe
extensions, using P20 through P24; the white plugs in each instrument slot. Only
instrument hub slot 1 on the M9505A uses P22, as shown in the single slot photo
below. For complete backplane photos, see “M9502A Backplane” on page 100
and “M9505A Backplane” on page 101.
Each Zone 2 plug provides 40 differential signal contact pairs with ground in 10
columns, four pairs to a column. The pin layout for P20 (typical for all Zone 2
connectors) is illustrated below the slot photo.
These plugs use male contacts; the mating module connectors J20 through J24
use female contacts. Note the areas shown with red boxes; these are for
alignment/keying.

Zone 2 Connector Usage
Your module may implement any or none of the Zone 2 connectors. If you want:
- to utilize the AXIe trigger, timing, data, and local bus (22 pair) features in your
module, load connectors J20 and J23.
- to expand the local bus up to 62 pair, load connectors J24 and J21.
- to complete a five-slot star hub for data fabric channel 2—used in instrument
hub modules only—load connector J22.

Updating the Chassis Firmware
Updating the Chassis Firmware
The current version of your chassis’ firmware is listed on the Home Page of the
web interface. See “Home Page” on page 44. You can update the AXIe chassis
firmware to take advantage of refinements and added features as they become
available. To check if a later version is available, go to the website below for your
product, then click the tabs/links indicated:
M9502A: www.keysight.com/find/M9502A, then Technical Support > Drivers &
Software > Firmware Update
M9505A: www.keysight.com/find/M9505A, then Technical Support > Drivers &
Software > Firmware Update
Revision string numbering format
The chassis firmware revision string is organized in the following format:
<Chassis Class>.<Firmware Version>-<Chassis Component>-<Axxxx>[-<Bxxxx>]…
Where: <Chassis Class> is either
F2AXIdentifies an M9502A 2 slot AXIe chassis
F5AXIdentifies an M9505A 5 slot AXIe chassis
<Firmware Version> is structured as: <major>.<minor>.<build>
<major>Identifies the major release number.
<minor>Identifies the minor release number.
<build>Identifies a build number.
<Chassis Component> is a four digit number, <xxxx>
Where <xxxx> is a hexadecimal value identifying the backplane firmware
revision. The backplane revision may be different between a 2 slot and 5 slot
chassis. While it is possible to move an ESM from one chassis to another, the
revision of the target chassis may not reside at the same revision level
installed on the ESM (and its previous chassis). It is important to review the
revision string after relocation to verify that the complete revision string is
current. If not up-to-date, run through the firmware update process.
<Axxxx>; <Bxxxx>...
<xxxx> is a hexadecimal value for the firmware component. The actual
content of these components is for Keysight internal use only.
A firmware revision example:
F2AX-1.3.37-0103-A002e-CA1.0-DA1.0-E1.3
This example shows an M9502A chassis with firmware revision 1.3.37. The
backplane revision is 0103 and component A is at revision 002e, component CA
is at revision 1.0, component DA is at 1.0, and component E is at 1.3. Refer to the

Troubleshooting
Overview
The Keysight AXIe chassis is typically used as part of a complex test system,
where system refers to the complete hardware/software system including:
- One or more AXIe chassis with installed application modules
- Connections from modules to devices under test (DUT)
- A host PC running Keysight Connection Expert software, chassis and module
device drivers, and programming environment software
- LAN connection from the Host PC to Chassis Web Interface software
- A compatible PCIe host cable adapter installed and configured in the PC
- Compatible PCIe and LAN interface cables
Troubleshooting that complete test system is beyond the scope of this chapter.
Keysight recommends that to properly isolate complex operational problems, you
take all routine steps to rule out a host software or connectivity issue.
You may also wish to physically isolate the chassis from your DUT or installed
modules, to distinguish a module hardware issue from a chassis hardware issue.
As a temporary measure, you may (with the chassis powered down) partially
remove a module without disturbing DUT connections, by removing it far enough
to disengage it from the chassis backplane.
Keysight recommends returning a failing chassis to Keysight Service. They will
inspect, test and replace failed components, then retest the chassis.
In general, an AXIe chassis has three major subsystems that can be replaced to
service a failing chassis:
- Fan Tray
- Power Supply Unit (PSU)
- Embedded System Module (ESM)
This chapter assumes you can identify a suspected faulty subsystem, or have
access to known good replacement subsystems you can swap to help isolate a
hardware problem. Detailed step-by-step instructions are provided for fan tray,
PSU, and ESM replacement.
Normal Chassis Operating Behavior
When the chassis is new and operating properly, familiarize yourself with its
expected normal power-up and power-down behavior. This behavior involves
these observable components:
- Front panel power switch (mechanical feel and indicator light)
- Rear panel circuit breaker (mechanical feel and resulting relay activation)

- ESM front panel STATUS light
- PSU fan operation
- Chassis fan operation
- Web Interface Chassis Health page (fan speeds, fan settings, fan/cooling
system status, backplane and slot temperatures)
1 OFF: With the chassis plugged into a correct power main, the rear panel
circuit breaker open (OFF) and the front panel switch off (flush with chassis),
all chassis lights should be extinguished.
2 BREAKER CLOSED: Close the circuit breaker (ON). You should observe:
– The breaker handle engages with a solid click, overcoming slight spring
pressure.
– After a slight delay, you may hear a softer click; this is a relay closing in the
PSU. You may not hear this relay close, due to PSU fan noise.
– The front panel power switch may light briefly, then extinguish.
– The two PSU fans will initially spin up to maximum speed, then gradually
step down in speed (4-5 distinct steps) to idle over two seconds. These
fans should remain on at idle with the breaker closed.
3 ON: Press the ON/STANDBY switch (turn the chassis ON). You should observe:
– The switch will depress (ON) and will light.
– The chassis fans will briefly turn on at high speed, then drop to and remain
at low speed, until chassis load dictates otherwise.
– The PSU fans will increase to and remain at high speed.
– The ESM front panel STATUS light will cycle as follows:
– Amber - ESM is booting; for about 20 seconds
– Flashing green - briefly
– Steady green - booted
– Steady red - the ESM has detected failure and requires service.
4 WHILE ON: With the chassis ON, you can monitor real-time shelf
management functions using the chassis’s Web Interface.
5 STANDBY: Press the ON/STANDBY switch again. You should observe:
– The switch should return to the flush position (OFF) and its light will
extinguish.
– The ESM front panel STATUS light will extinguish.
– The chassis fans will turn off.
– The PSU fans will slowly drop in speed, while continuing to cool the PSU
from operating temperature to standby temperature.
– Once the PSU cools down, the PSU fans will return to a steady idle speed.
6 OFF: Open the circuit breaker (OFF). You should observe:
112

– The breaker handle releases spring pressure.
– After a slight delay, you should hear a soft click; this is a relay opening in
the PSU. You may not hear this relay open, due to PSU fan noise.
– The front panel power switch may light briefly, then extinguish.
– The two PSU fans will turn off.
Chassis Hardware Troubleshooting
Chassis Fans
If module loads are kept within the 200W per slot rating and adequate ventilation
is provided around the chassis, the chassis fans are designed to automatically
cool the chassis. If the chassis powers up properly, the fans should be turning at
all times, with speed in proportional to thermal load.
There are a few reasons you may suspect a fan tray failure:
- One or more fans does not turn.
- A fan makes excessive bearing noise.
- You observe reduced speed for one or more fans relative to the others.
- One or more fans do not behave as described in “Normal Chassis Operating
Behavior” on page 111.
- You experience an overheat condition, whether detected by the chassis
Health Monitor, module monitoring software or other means.
In the event you experience unacceptably high chassis or module operating
temperatures or other indications of fan failure, follow the procedure below.
To Check Chassis Fan Operation In the event you experience unacceptably
high chassis or module operating temperatures, or other indications of fan
failure, follow the procedure below.
1 Visually check that all three (M9502A) or six (M9505A) fans are turning. If any
fans are not turning, check for and remove obstructions. If there is evidence of
excessive buildup on the fan blades, remove the fan tray to clean and reinsert
it (see page 124), and recheck. If any fans still do not turn, replace the fan
tray. Else continue.
2 Using the Web Interface, access the Chassis Health page. In the Sensors
section, each fan is listed individually, with real time speed in rpm.
3 The six speeds should be reasonably close. Identify any that turn more slowly
than the group. Any large deviation may indicate reveal early signs of fan
failure.
4 Below the fan speed readouts are your fan settings. You may set a higher fan
speed to see if the fans are responsive.

Troubleshooting and Service
Troubleshooting
5 For fan noise problems, make sure which fans are noisy or not turning
properly, by visually inspecting both the PSU and chassis fans through the
side of the chassis.
6 For all routine chassis fan failures, replace the fan tray assembly (see “To
Replace the Fan Tray” on page 124). For PSU fan failures, replace the PSU
(see “To Replace the Power Supply Unit” on page 118).
If the fans are operating correctly and you still have high temperatures, reduce
your chassis load or troubleshoot installed modules.
Power Supply Unit (PSU)
The PSUs are self regulating, constant voltage supplies that will shut themselves
down (or not power up at all) if they are out of spec. These are standard ATCA
supplies.
The PSU operation is binary. If the supply is delivering voltage within a very wide
range, it will turn on its output and power up the chassis. You can then view PSU
voltages using the Web Interface. If the system does not power up, it likely has
failed and should be replaced (see “To Replace the Power Supply Unit” on
page 118).
Embedded System Module (ESM)
If, upon power up, the ESM does not boot to a steady green STATUS light,
replace the ESM (see “To Replace the Embedded System Module” on page 124).
If replacing the PSU or ESM does not correct an operating problem, and the ESM
still fails to boot to a steady green STATUS light, the problem is in the remainder
of the chassis; replace it.
To Reset ESM DIP Switches The ESM has several sets of dual in-line
package (dip) switches. Should you believe any of these may have been
changed, you may verify and reset them to their correct positions; see photo and
table below.
Most of these switches are reserved for factory testing purposes or reserved for
future use and should not be changed.

Troubleshooting and Service
To Replace the Power Supply Unit
To Replace the Power Supply Unit
PSU replacement should be performed at a static-safe work station (see“ESD
Precautions” on page 11), preferably on the bench. While it is possible—given
adequate room for access—to perform this job with the chassis rackmounted,
extra caution must be taken to avoid damage to the chassis’ back panel wiring or
loss of small parts.
To remove the PSU from the M9502A
Tools needed: #8 and #10 Torx drivers.
1 Power down and disconnect the power cord from the chassis.
2 If the chassis is rack-mounted, remove it from the rack.
3 If installed, remove the carry handle and rear bumper (see “To Remove the
Carry Handle and Bumpers from the M9502A” on page 30).
4 Position the chassis top panel down. Remove the three #8 Torx flat head
screws from rear edge of the bottom panel.

To Replace the Fan Tray
To Replace the Fan Tray
The illustrations below show the M9502A; the procedure is identical for the
5-slot chassis.
1 Power down and unplug the AXIe chassis.
2 Fully loosen the two captive retaining screws on the front panel of the fan tray.
Ensure you fully loosened the captive retaining screws before trying to extract
the fan tray. If you attempt to pull the fan tray out by the screws with these
screws still engaged, damage could result.
3 Grasp the fan tray by the two captive retaining screws, and slide it out of the
chassis.
4 To install the fan tray, reverse these steps.
To Replace the Embedded System Module
Remove and reinstall the ESM exactly like an application module, except that it
can only fit in the bottom half-height slot. See “Installing Modules” on page 23
for instructions.

LPC Low Pin count. An interface specification for legacy I/O. Allows legacy I/O
of motherboard components, such a Super I/O chip, to migrate from the ISA/X
bus to the new LPC interface while retaining software compatibility. It runs at the
PCI 33MhZ clock making LPC much faster than the older ISA running with an
8MHz clock.
MultiFrame MultiFrame is a Keysight feature in which multiple measurement
instruments in two or more chassis are interconnected to appear as one integral
instrument to the user. In a MultiFrame system, special daisy-chain cabling
connects the time base and triggering of the master chassis to all slave chassis.
These cables extend trigger and timing features to instruments not connected to
the master chassis’s backplane. You can use the MultiFrame configuration to
increase the number of measurement modules utilizing a common time base or
cross triggering. Refer to “MultiFrame Operation” on page 89 for more
information.
Multiple Chassis In a multiple chassis system, multiple chassis are controlled
by a single controller, and the time base and triggering for each chassis operates
independently from the other chassis. You can use the multiple chassis
configuration to increase the number of chassis/modules that do not require a
common time base or cross triggering between chassis. For more information,
refer to Keysight's Multiple PXIe and AXIe Chassis Configuration tool. This tool is
available on the M9018A Product information CD as well as on line at:
www.keysight.com/find/pxie-multichassis.
