Introduction M9506A 5-Slot AXIe Chassis Description
M9506A 5-Slot AXIe Chassis Description
The Keysight M9506A AXIe chassis is a modular instrument chassis fully compatible with the AXIe Wide PCIe specification. It allows multiple application-specific instrument modules to share a common chassis frame, power supply, cooling system, PCI Express (PCIe) x16 Generation 3 (Gen 3) backplane, Gigabit LAN hub, local bus for module-to-module signaling, and host
PC connections. The full rack chassis provides five general purpose peripheral slots that accept 1U AXIe instrument modules.
Additional features include:
– Up to 300 W per slot power
– Five AXIe Wide compliant slots
– PCIe x16 Gen 3 Backplane allows module to module communication
– Default PCIe configuration merges both cable ports to one Gen 3 x16 PCIe
Cable Port.
– Open AXIe Zone 3 for custom use (cable access, analog backplane, etc.)
– Thunderbolt 3 Connection Port *
– Cascaded PCIe for multiple chassis systems
– Parallel and Star Triggering
– Push-pull fan system for quieter operation
The chassis includes a half-height Embedded System Module (ESM) which manages chassis functions. The ESM provides all shelf manager functions, plus these AXIe extensions:
– host PC connectivity (Gen 3 PCIe x8/x16, Thunderbolt 3, Ethernet)
– sources timing signals (CLK100, SYNC and FCLK)
– routes STRIG (Star Trigger) to instruments through the backplane
– two bi-directional trigger front panel access ports route trigger signals through to the backplane parallel trigger bus and Star Triggers to each slot
– provides backplane PCIe and Ethernet communication between modules
Other than a power button/status light (on the ESM), all monitoring, control and communication with the chassis requires a host PC . This can be an embedded PC specifically designed for use in an AXIe chassis (such as the Keysight M9537A
Embedded Controller) or remote (a rackmount, desktop, or laptop) PC.
The Gen 3 PCIe Cable Interface ports provides up to a 8GB/s (theoretical) for Gen
3 x8, and 16 GB/s (theoretical) for Gen 3 x16. The Thunderbolt
Gen 3 x4 link with up to 4 GB/s (theoretical) bandwidth.

M9506A 5-Slot AXIe Chassis Description Introduction
What is Thunderbolt 3?
Thunderbolt 3 provides PCI Express (PCIe) connectivity with data transfer rates at up to 40 Gbps * . There are no Upstream or Downstream ports with Thunderbolt 3.
Thunderbolt 3 uses USB-C and requires Thunderbolt
3 certified cables for correct operation. To quickly check whether the port you have on a host PC is a
USB-C or Thunderbolt 3 version, look next to or just above the port for a Thunderbolt icon (a lightning bolt).
† Your host PC must have a Thunderbolt 3 port. Even though they use the same cables, Thunderbolt 3 is not USB-C compatible. Thunderbolt 3 cables have no polarity and are reversible – connect either end to the PC or chassis.
Plugging a Thunderbolt 3 device into a Thunderbolt 3 port, provides between 20 and 40 Gbps maximum throughput, depending on the type of cable you're using:
Passive Thunderbolt 3 cables are identical to USB-C cables and plug into
Thunderbolt 3 or USB-C ports and achieve data rates up to 20 Gbps.
For maximum data transfer rate over Thunderbolt 3, use active cables. Active
Thunderbolt 3 cables achieve full 40 Gbps throughput. Active optical cables can extend connection length from 6 feet up to approximately 200 feet.
Factory default is PCIe Cable Ports configured as x16 Gen 3. If you want to use the Thunderbolt 3 port, you must set a switch on the
ESM. See “SW56 Switch Positions” on page 143.
Thunderbolt 3 is hot-swappable. However, avoid removing the cable after the system is powered on. Doing so may cause errors in data transmission.
Do not connect USB Type C (USB-C) devices into the Thunderbolt port on the M9506A ESM.
* Thunderbolt 3 provides PCIe connectivity and provides faster data transfer than a standard PCIe interface. It requires short, <0.5 M or active Thunderbolt 3 cables for highest speed. Charging devices such as laptop computers over Thunderbolt 3 is not supported on the M9506A.
† The original Thunderbolt and Thunderbolt 2 interfaces use mini DisplayPort-shaped connectors that are not compatible with Thunderbolt 3.

M9506A AXIe System Block Diagram Introduction
M9506A AXIe System Block Diagram
“M9506A AXIe System Block Diagram (Graphic)” on page 19 shows a block
diagram of a M9506A 5-slot AXIe chassis system, showing the chassis and the host PC. The key points regarding this diagram are:
The diagram shows the host PC interfaces to the chassis: (1) The PCIe Cable ports, (2) Thunderbolt 3 interface, and (3) the LAN interface. The PCIe Cable ports and Thunderbolt links route through the ESM PCIe Switch to the slot x16 PCIe links. The LAN interface links are routed through the LAN Switch to the slot Gb Ethernet signals. The PCIe and Thunderbolt interface links can also be routed to the slot Gb links (through the network interface controller and the LAN Switch). However, the LAN interface links cannot be routed to the slot x16 PCIe signals.
The network interface controller (NIC) is an Intel I210 NIC. The PCIe Switch and the NIC provide an x1 path from the chassis PCIe interface to the LAN
Switch and, ultimately, the Shelf Manager (described further below).
If you’re using the PCIe interface to connect to the chassis, the Intel I210 NIC will appear to Windows as a locally-installed device. Windows 7 and Windows
10 provide the necessary Intel NIC driver.
Install either the M9048B or the M9049A PCIe Desktop Adapter in the host PC to provide a PCIe interface. The PCIe Desktop Adapter is used in desktop or rack-mount computers. A PCIe cable (Y1202A, 2.0 m cable) connects the adapter to the AXIe chassis. For Thunderbolt access, a standard Thunderbolt cable connects the ESM to the host PC. For LAN access, a standard Ethernet cable connects the ESM to the host PC.
The chassis contains a processor called the Shelf Manager that monitors the status of the chassis sensors and the module sensors over the Intelligent
Platform Management Bus (IPMB). The Shelf Manager also controls the fan speeds and provides the chassis Web Interface. The Web Interface allows you to use your browser to monitor the status of the chassis and configure certain aspects of chassis operation, such as the trigger subsystem.
The chassis supports two Soft Front Panel (SFP) utilities. SFP runs on the host
PC and provides the same monitor and control functionality as the chassis

Introduction M9506A AXIe System Block Diagram
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.
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/M9506A .
For general host PC requirements, such as operating system and
RAM requirements, please refer to the M9506A AXIe Chassis
Startup Guide.

Introduction ESD Precautions
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.

The chassis and host PC must be powered up and down in the following sequence. The chassis should be powered up first, which initiates its built-in
Power-on Self Test (POST). During POST, the chassis 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 M9537A handles this sequence automatically.

(High = powered up)
The STATUS LED flashes green at power-on while the chassis performs self test. It will stay green continuously when the
ESM is ready. The ESM then powers up each module slot.
Chassis
STATUS LED module initialization
The PC should be turned on only after all installed modules have performed their initialization. See your module documentation for initialization information.
Host PC
(High = turned on)
The chassis must be powered up before the
PC is turned on to ensure that the PC
BIOS will enumerate the chassis slots as the PC boots.
If, while the chassis was powered down, its configuration was changed in any way, the PC may need to be restarted after
Windows comes up (as indicated by the Windows splash screen).
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.
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 possible 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
100 ms. Consequently, it is possible for some controllers (such as the Keysight M9537A 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.
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 may need to be restarted (after
Windows starts) if the chassis configuration was changed in any way while the chassis and embedded controller were turned off.
Keysight M9506A 5-Slot AXIe Chassis User Guide 23
Introduction Power-Up and Power-Down
To Power Down the Chassis
For routine power-down or to cycle power to the chassis, momentarily (< 5 seconds) press the chassis
ON/STANDBY
switch. The main chassis fans gradually drop in speed to off, and the power supply unit (PSU) fans gradually return to idle speed as the PSU cools. This is normal.
If you are using an embedded AXIe controller such as the Keysight
M9537A, pressing he ESM power switch initiates a Windows OS shutdown.
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 may 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.
Pressing and holding the power ON/STANDBY switch for greater than five (5) seconds shuts down the power supply immediately. If the chassis is in a fault condition, the fault resets and the chassis goes to the OFF state.
24 Keysight M9506A 5-Slot AXIe Chassis User Guide
Power-Up and Power-Down Introduction
The Chassis INHIBIT Switch
The method of powering up the chassis depends on the position of the INHIBIT switch on the chassis rear panel, which can be set to the DEF ( DEF ault) position or to the MAN ( MAN ual) position. These two methods work as follows:
- INHIBIT switch in the DEF position — In this position, the front panel power push button is used to switch the chassis between ON and Standby—hence, this is known as the ON/Standby push button.
- INHIBIT switch in the MAN position — In this position, the Inhibit signal (pin 5 on the DB-9 connector) controls chassis power. The chassis is powered up by applying a logic high signal to the Inhibit signal. When the Inhibit pin (pin 5) is pulled low, the chassis is in Standby. This is the factory default position
Use of the INHIBIT switch in the DEF position and the ON/Standby push button to power up the chassis is assumed unless otherwise noted. For information on using the Inhibit signal on the rear panel DB-9 connector to power the chassis up and down, see “Chassis Inhibit/Voltage Monitoring” on page 98.
Inhibit Switch
Figure 1 Chassis Power Inhibit Switch, DB9 Connector, Power Sync Connectors
Leave the INHIBIT switch in the DEF position when connecting the
AC power cord to the chassis. After inserting the power AC power cord, then move the INHIBIT switch to the MAN position.
The RJ45 connectors are for multiple chassis power-up synchronization. Cables used for multiple chassis power-up synchronization purposes should not exceed
30 m in length. Straight CAT5 or better cables recommended. Refer to
“Multi-Chassis Power Sync” on page 114 for information on these connectors.
The RJ45 connectors are for multiple chassis power-up synchronization. Do not connect LAN cables from your corporate
LAN to these connectors.

Installing and Removing AXIe Modules Chassis Installation
Installing and Removing AXIe Modules
The AXIe chassis accepts modules conforming to the single slot, 1U AXIe standard. These may include:
AXIe embedded controller module
AXIe Filler Modules; chassis are NOT shipped with AXIe Filler Modules. These are order-able separately with Keysight part number Y1221A.
The insertion and removal procedures are the same for all module types except filler modules.
Static Electricity —The components and connectors on modules are sensitive to static electricity. To minimize electrostatic damage, take the necessary anti-static precautions.
Empty Slots —Except for performing initial chassis verification or troubleshooting, do not operate the chassis with empty slots. Always insert a filler 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.

Align the module’s circuit board with the guide rails on both ends of the chassis. If the module has metal plates covering the circuit board, be sure to insert the circuit board and not the metal plates into the rails. Slide the board gently into the two rails. If the fit is tight, slide the board back out and recheck alignment.
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.

Slide the module completely into the chassis. When the module’s backplane connectors contact the chassis backplane, you will feel resistance and the two handles will begin to close toward each other. The module’s faceplate will be about 1 cm from the chassis front panel.
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.
Tighten the captive retaining screws at both sides of the module.

Power down but do not unplug the AXIe chassis from the AC power.
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 Modules) or by using the extraction handles (other modules) with these screws still engaged, damage to the chassis or module could result.
3 For an AXIe Filler 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.

Chassis Installation Setting Up a Host PC
Setting Up a Host PC
Following the M9506A 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 M9506A 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.
Installing Module Soft Front Panel and Device Drivers
Each installed module typically requires device drivers and control software. You do not need to install them to verify basic chassis operation, but would logically install them on the host PC at this time. For Keysight instrument modules, refer to the instrument page at Keysight.com. For others, consult the module provider for software requirements and instructions.
External PC, PCIe x16 Connection to Single M9506A
The following configuration represents the highest throughput (x16) between the
PC and one chassis. Make certain that all switches on the interface modules are set correctly to configure this operation. Make certain the top connector on the
M9049A module connects to the left PCIe connector on the M9506A ESM module and the bottom connector on the M9049A module connects to the right
PCIe connector on the M9506A ESM module.
The default PCIe Cable Port Configuration is x16 as shown in the following figure. This requires using both PCIe Cable Ports on the front of the ESM. To change the configuration to two x8 ports, you
must set a switch on the ESM. Refer to “SW56 Switch Positions” on page 143.

Verifying Operation with Modules Installed Chassis Installation
Verifying Operation with Modules Installed
In the M9506A AXIe Chassis Startup Guide , you should have verified basic power-on operation of the AXIe chassis and communication with the host PC.
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 the PCIe or
Thunderbolt 3 ports to control AXIe modules.
Power up the chassis and wait for the solid green status light on the ESM.
Wait for the modules Status LED to trun green.
Power up 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 the chassis and all 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.
The chassis Shelf Manager (on the ESM) knows whether the power supply is connected to a Low Line or a High Line AC source and the power the installed
AXIe modules are requesting. At power-up, if the modules are requesting more power than is available, then the Shelf Manager prevents one or more modules from powering up.
For example, if a chassis is connected to a Low Line AC source (940 W maximum) but five modules are installed in the chassis and each module attempts to draw
200 VA, then only four of them will power on – the fifth would require more power than is available. In this situation, you would need to connect the chassis to a
High Line AC source.

Chassis Installation Using the M9537A Embedded Controller LAN Ports
Using the M9537A Embedded Controller LAN Ports
If you installed a Keysight M9537A Embedded Controller in the Keysight AXIe chassis, there are a total of three LAN ports accessible on the front panels -- two on the M9537A 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.
40
Note that NIC 3 is not used. NIC numbering on your controller may be different.
Figure 5 Windows Device Manager showing Network Connections
This section provides overall guidance on selecting and using the M9537A 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 (including Thunderbolt 3) 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.

Shut down Windows on the M9537A Embedded Controller.
After Windows shuts down, power down the AXIe chassis using the chassis power button.

Power up the AXIe chassis using the chassis power button.
Run Keysight Connection Expert and verify that the LAN interfaces are operating correctly and that Connection Expert finds the AXIe chassis.
Keysight Connection Expert should automatically identify the AXIe chassis and installed modules.
General Recommendations
As a general rule, connect a network LAN cable to the ESM’s LAN port and connect LXI instruments to the M9537A’s LAN ports. While other configurations are viable, this configuration provides the fastest and most consistent reporting in Keysight Connection Expert. Refer to
.
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 remove a LAN cable while chassis power is applied, Connection Expert may not find all of the instruments available on the network.
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 M9537A 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 M9537A 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 M9537A Embedded Controller installed in the AXIe chassis, the x8 PCIe connection and the Thunderbolt 3 port on the ESM module are disabled. However, the PCIe cable detect mechanism may reset the hardware when attaching a PCIe cable. This hardware reset may change the IP address.

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 M9506A chassis weighs 23.5 kg (51.8 lbs) with ESM but no other installed modules. It weighs significantly more fully loaded with AXIe modules. It is typically used rackmounted, but can also be used on the bench, with proper support and ventilation.
AC Input
The chassis power limits are:
100/120 VAC (Low Line), 50-60 Hz
1380 W maximum
200/240 VAC (High Line), 50-60 Hz
2000 W maximum
The instrument can operate with mains supply voltage fluctuations up to 10% of the nominal voltage.
The main power cord can be used as the system disconnecting device. It disconnects the mains circuitry from the mains supply.
The chassis Shelf Manager (ESM) knows whether the power supply is connected to a Low Line or a High Line AC source and the power requested the installed
AXIe modules. At power-up, if any module requests more power than is available, then the Shelf Manager prevents one or more modules from powering up.
For example, if a chassis is connected to a Low Line AC source (940 VA maximum) but five modules are installed in the chassis and each module attempts to draw 200 VA, then only four of them will power on – the fifth would require more power than is available. In this situation, you would need to connect the chassis to a High Line AC source.
powered on.
Keysight M9506A 5-Slot AXIe Chassis User Guide 45
Chassis Installation Mounting the Chassis
Avoid overloading an electrical circuit. Ensure your AC power line 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 disconnect.
If the chassis is rackmounted, this primary disconnect can be a power system on the rack or the circuit breaker on the chassis.
Ventilation
The chassis is designed to dissipate up to 300 W * 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 at least 2” (5 cm) clearance around both sides of the chassis.
Airflow through the chassis is from right to left; that is fresh air is drawn in from the right side and exhausted from the left side.
Do not block the vent holes on the chassis. This may cause overheating and damage to components. Leave a gap of at least
2” (50mm) around all vent holes and fan exhaust areas.

When installing the instrument(s) into a cabinet consideration shall be given to the convection flow into and out of the cabinet. Consideration shall also be given to the individual instruments to avoid having the heated discharge of one instrument, now becoming the cooling intake air for another instrument.
Another area of concern is verification that the maximum ambient operating temperature of the instrument(s) is not exceeded by cabinet installation.
Keysight recommends forced air convection whenever an instrument(s) are

If there are any concerns or special requirements a Keysight Field Engineer should be consulted to assure instrument(s) temperature compliance and performance."
Rackmounting the Chassis
Keysight’s Y1227A Rack Mount Kit, is required to rack mount the M9506A chassis. The kit includes mounting instructions and parts.
General Rack Mounting Guidelines
To rack mount the chassis, follow these guidelines:
– Always begin installing the chassis and heavy instruments at the bottom of the rack and work up. This maintains a lower center of gravity and reduces the possibility of the rack tipping.
– Anti-tipping feet, if available with the rack, should always be extended.
– For maximum cooling and optimum rack thermal efficiency, place the instrument or chassis with the greatest power consumption towards the top of the rack. This promotes efficient cooling since heat rises when placed nearer to the top of the rack, high power instruments will not unnecessarily heat other instruments. However, in doing this, do not violate the guideline that the heaviest instruments should be placed at the bottom of the rack.
– If instruments or modules in the chassis are consuming maximum power,
1U of rack space is required for ventilation below the chassis.
When removing the bumpers, 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 to ship the chassis.
If you have been using the chassis with modules and bumpers installed, remove all modules (including the ESM) before removing the bumpers. This makes handling the chassis easier and reduces the chance of damaging modules. See
“Removing a Module” on page 34.
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

E-Keying (short for Electronic Keying) is a process in which compatible matches over links between different modules are identified and enabled for use. For more information on the details of E-Keying, refer to
“Electronic Keying (E-Keying)” on page 97.
In general, you do not need to understand how E-Keying works. The E-Keying process is managed by the ESM shelf manager. The following two figures illustrate the Module E-Keying Activity display in the Module Configuration Page.
In the following graphic, 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.

This chapter provides a brief overview of the two M9506A AXIe chassis Soft Front
Panel (SFP) drivers– Monitor SFP and Trigger SFP . While the Web Interface runs in a browser window and accesses the web server built into the chassis, the SFPs are executables which run on a PC and communicates to the chassis using the IVI drivers. SFPs are installed automatically when the chassis IVI drivers are installed.

Two SFP drivers are included with the M9506A – a Monitor SFP and a Trigger SFP . Both drivers are installed automatically when you install the IVI drivers. Make certain that you use the appropriate
SFP for your purposes. Refer to the SFP Help files for detailed information.
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.

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

Configure Fan Control Features and Functions
Configure Fan Control
The minimum chassis fan speed is approximately 600 RPM; the maximum fan speed is approximately 6000 RPM. Using a range of 10 to 100 (percentage of maximum), you can manually set the minimum speed you want the fans to operate at — 10 means the fan speed of approximately 2200 RPM and 100 is the maximum fan speed of approximately 6000 RPM.
Do not attempt to set the fan speed below 10 %.
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 Fan Control page has the following five 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 approximately 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.
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, as are the thresholds for alarm conditions. Typically only high temperatures generate an alarm, although it is possible 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, it may not indicate that the module has failed, only that continued operation is inadvisable until the module cools.
Refer to the Chassis Health page for detailed information about individual modules, temperature alarms, etc.

Features and Functions Configure Fan Control
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 10 to 100, where 10 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 10.
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 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 programmatically. 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.
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 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 happen frequently causing the fan Current Speed Level to change and the
Dynamic Minimum Fan Speed to gradually change.

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.
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.

Features and Functions Configure Fan Control
Controlling Fan Speed
You can set the minimum fan level , over a range from 10 to 100 as a percentage of maximum fan speed, by setting that level in the Adjust Current Speed Level and
Dynamic Minimum Fan Level fields and clicking the Apply button. This specifies the minimum level at which you want the chassis fans to run. The Shelf Manager increases fan speed from that minimum 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 77.
The power supply (PSU) fans are controlled automatically, you cannot manually override them.

Self-Test
Self-Test
Features and Functions
The ESM supports two types of self-test:
– Power-on Self-Test (POST) – This test happens on the Shelf Manager as soon as the chassis powers up. As noted, this type of self-test is referred to as “POST”.
– After-POST self-test – This test is initiated by the user either via the SFP or programmatically using the Self-Test IVI call:
KtMAXIeMon.Utility.SelfTest(“TestResult”,”TestMessage”); .
Unless noted otherwise, references to “self-test” always refers to the self test that is either initiated from the SFP or initiated programmatically. The phrase
“self-test” does not refer to POST.
The front panel Status LED shows the following LED states:
– OFF - standby
– Green (blinking) - ESM/Shelf Manager is booting up and waiting for modules to be ready for enumeration
– Green (solid) - power up complete and ready for enumeration
– Red - failure/service required.
The power on self-test (POST) routines are automatically executed at power on.
If POST passes, the status LED will be solid green. If POST fails, the status LED continues blinking green.
If POST passed (the Status LED is green), and then self-test is subsequently run and fails, the Status LED begins blinking green. Similarly, if POST failed (Status
LED blinking green), but then if self-test is subsequently run and passes, the
Status LED turns solid Green.
Regardless of what causes the Status LED to blink green (a POST failure or a failure during running of self-test), it will turn solid green again if Self-Test is run and passes.
Self-test runs a series of tests and any failure generates an error consisting of an error code ( TestResult ) and error message ( TestMessage ).
A single Self-Test error queue in the ESM holds both the power-on self-test errors and the user-initiated self-test errors. Power-on Self-Test error messages are identified by the “(POST)” prefix; user-initiated self-test messages do not have a prefix.
Running the user-initiated self-test (either from the Soft Front Panel or programmatically) preserves any unread power-on test messages in the queue, but erases any other (user-initiated) unread messages before running the tests.
You can use the Soft Front Panel or the IVI Self-TestErrorQuery call to view the errors.

GPS Synchronization Features and Functions
GPS Synchronization
The M9506A-GPS option adds GPS synchronization ability along with an external antenna port on the front panel. It provides an accurate 1 Pulse Per Second
(PPS) output; the 10/100 MHz reference can be locked to this clock. The PPS signal can be propagated to trigger I/O and trigger events can be timestamped.
Other GPS information is also provided including latitude, longitude, and altitude direction and speed.
– Propagate the 1 PPS output to modules via backplane trigger resources.
– GPS can generate up to 4 future trigger events at a specified time-stamp.
Event can be routed to any trigger resource tied to the crosspoint switch.
– GPS can time-stamp trigger events from any source with the
GPS-synchronized Time of Day (ToD). Trigger Events can be come from any trigger resource tied to the crosspoint switch.

Clocks and Triggering
Keysight’s M9506A AXIe chassis provides several triggering and timing options.
These allow you to achieve time-aligned operation of multiple instrument modules installed in the chassis.
Although the triggering and timing options can be inter-operated, it is easiest to understand them using distinct Clock Bus and Trigger Bus subsystems, 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 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 SMB connector CLOCK OUT , as a 10 MHz external reference clock (3.3V CMOS, 50 )
A separate 100 MHz distributed PCIe fabric reference clock ( FCLK ) is provided from the ESM to all instrument slots.
Clock Sources
There are two sources for the clock bus in a given chassis: the default internal source and the external 10MHz Clock In (SMB connector on ESM front panel). Clock detection logic is automatic, and the input source is chosen in the following priority order, depending on whether the external clock input is sensed:

Features and Functions Clocks and Triggering
Triggering
This section introduces the trigger bus resources and some of the many ways you may use them. Any AXIe instrument module 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
Through the Crosspoint Switch, the AXIe chassis allows you to trigger instruments—singly, in groups, or all instruments in the chassis—from different signal sources. The diagram below shows how the triggering resources are derived .
88
The primary 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:
– External trigger ports TRIG1 and TRIG2 applied at the ESM’s front panel
SMB connectors. Input characteristics: 3.3V CMOS drive, 100 mV minimum swing, 50 output termination.
– Any of the TRIG[0:11] signals. As these 12 lines are bidirectional, any AXIe module can source a trigger via the backplane. TRIG bus resources are allocated through E-Keying on the parallel trigger bus between two adjacent modules if they are designed for E-Keying (see
– Any of the five STRIG signals. As these lines are bidirectional, any AXIe module can source a trigger via the backplane using them.
– Software Trigger. A trigger signal generated on the ESM by driver software can be sourced to any of the trigger lines.
Keysight M9506A 5-Slot AXIe Chassis User Guide
Clocks and Triggering Features and Functions
Trigger Outputs
From the diagram above, note that the Crosspoint Switch can output trigger signals to any of the following:
– External trigger ports TRIG1 and TRIG2 driven from the ESM’s front panel
SMB connectors to external instruments. Drive characteristics: Push-Pull mode: 50 , 3.3 Vdc CMOS drive. Open Drain mode: pull-up to 3.3 Vdc through 318 .
– Any of the TRIG[0:11] signals. As these 12 lines are bi-directional, any AXIe module can source a trigger via the backplane. TRIG bus resources are allocated through E-Keying on the parallel trigger bus between two adjacent modules if they are designed for E-Keying (see
– Any of the five STRIG signals. As these lines are bidirectional, any AXIe module can source a trigger via the backplane using them.
– SYNC provides a trigger signal output at the next rising edge of CLK100 after the source trigger is received. This creates highly synchronous applications by triggering multiple instruments both simultaneously and in sync with the reference clock.The SYNC and CLK100 lines use fan out buffers and are trace length matched.
Each type of trigger output signal is explored in detail, after a closer look at the
Crosspoint Switch.

The Crosspoint Switch Features and Functions
The Crosspoint Switch
The M9506A ESM’s Crosspoint Switch, shown in the block diagram on
, provides the flexibility of routing many trigger signal events from AXIe instrument modules, external trigger, or a software-generated trigger to different destinations. You can enable and assign any of the input sources for any or all of signal destinations (trigger/timing resources). You can also source a logical 0 or
1 to force any destination low or high.
The M9506A Soft Front Panels are a good way to start learning about the
Crosspoint Switch. This utility offers basic switch control and other basic M9506A operations, such as running Self-Test. After the chassis drivers are installed, either SFP can be started from the Start menu as follows:
Start > Keysight > AXIe Chassis Monitor SFP
Start > Keysight > AXIe Chassis Trigger SFP
Outputs
Each of the Crosspoint Switch outputs (see the Trigger Subsystem and block diagram beginning on
page 84 ) can be enabled and driven independently.
An output must be enabled before it can be used as an output.
Inputs
Any of the Crosspoint Switch inputs (see the Trigger Subsystem and
block diagram beginning on page 84
) can be assigned to any output, except that you cannot assign the same input as the output. If multiple input sources are specified for an output line, the sources are logically ORed together to produce the signal on that output line.
The default input for all outputs is “Static 0”. If you don’t specify the input signal for a specific output signal, the input signal will be logic 0 by default for that output signal.

Monitoring Crosspoint Switch Outputs
Each of the Crosspoint Switch outputs (see Figure 26
) can be enabled and driven independently. An output must be enabled before it can be used as an output.
Monitoring Crosspoint Switch Inputs
Any of the Crosspoint Switch inputs (see Figure 26 ) can be assigned to any
output, except that you cannot assign the same input as the output. The X’s on the Crosspoint Switch diagram indicate disallowed connections.
The default input for all outputs is “Static 0”. If you don’t specify the input signal for a specific output signal, the input signal will be logic 0 by default for that output signal.
OR-ing and AND-ing of Input Signals
When multiple Crosspoint Switch input signals are connected to a single output line, the signals are logically ORed together to produce the signal on that output line. That is, when any of the inputs are logic “1”, the output will be logic “1”. The truth table for a two-input OR gate is shown below.
By inverting both inputs and the output of an OR gate, the equivalent of an AND gate is achieved, even though the Crosspoint Switch is still performing an OR function internally. That is, when all inputs are logic “1”, the output will be logic
“1”. The truth table for a two-input AND gate is shown below.

PCIe and LAN Switching (Data Transfer) Features and Functions
PCIe and LAN Switching (Data Transfer)
Data Channels Explained
The AXIe chassis provides four paths for communication and data transfer to and from installed modules:
– Gigabit (Gb) Ethernet
– PCIe
– Thunderbolt 3
Gigabit (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 x16.
– From the PCIe switch in the ESM to two PCIe x8 front panel connections.
Thunderbolt 3
Thunderbolt 3 provides one PCIe interface using a USB-C
Connector. The ESM front panel PCIe ports are disabled when using the
Thunderbolt port .
Maximizing Data Upload Speeds
The maximum data bandwidth to each slot is dictated by the x16 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 one or two x8 cables, the primary data fabric utilizes a x8 or x16 connection between the ESM and the host PC. The ESM’s PCIe switch can achieve Gen3 upload speeds when transferring data to the host from multiple modules simultaneously.
– If an embedded controller is installed in the chassis, the ESM front panel
PCIe x8 connections become downstream facing and can connect to other chassis. The embedded controller uses its backplane PCIe x16 link to link the ESM PCIe switch.
Keysight M9506A 5-Slot AXIe Chassis User Guide 95
Features and Functions PCIe and LAN Switching (Data Transfer)
Thunderbolt, PCIe, or LAN?
You can establish communication between the chassis and host PC over a PCIe,
Thunderbolt, or LAN connection. In practice, the choice is usually driven by the interface(s) on your modules. For example, if you have a module with a PCIe interface, you’ll want to establish a PCIe connection to the chassis.
Thunderbolt
Thunderbolt 3 with USB-C Thunderbolt 3 provides bi-directional, four lanes of PCIe Gen 3 * . The ESM front panel PCIe ports are disabled when using the Thunderbolt port
.
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 than 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. The ESM front panel PCIe ports are disabled when using the Thunderbolt port
.
96
* Thunderbolt 3 also provides eight lanes of DisplayPort 1.2 and native USB 3.1. However, these features are not supported on the M9506A ESM.
Keysight M9506A 5-Slot AXIe Chassis User Guide
Electronic Keying (E-Keying) Features and Functions
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.
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 graphic below.
Keysight M9506A 5-Slot AXIe Chassis User Guide 97
98
Features and Functions Electronic Keying (E-Keying)
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) module.
*
inventory located in non-volatile memory that tracks ATCA and AXIe attributes from each
-- 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.
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.
* 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 M9506A 5-Slot AXIe Chassis User Guide
Electronic Keying (E-Keying) Features and Functions
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
).
Keysight M9506A 5-Slot AXIe Chassis User Guide 99
Features and Functions Chassis Inhibit and Voltage Monitoring
Chassis Inhibit and Voltage Monitoring
The method of powering up the chassis depends on the position of the INHIBIT rear panel switch, which can be set to the DEF (default) position or to the MAN
(manual) position). These two methods work as follows:
– INHIBIT switch in the DEF position — In this position, the ESM front panel power push button switches the chassis between ON and Standby—hence, this push button is known as the ON/Standby push button.
– INHIBIT switch in the MAN position — In this position, the Inhibit signal (pin 5 on the rear panel DB-9 connector) controls chassis power. The chassis is powered up by applying a logic high signal to the Inhibit pin. When the
Inhibit pin (pin 5) is pulled low, the chassis is in Standby.
Chassis Inhibit Switch
DB9 Connector for measuring
PSU voltage rails
100
Figure 27 Chassis Power Inhibit Switch, DB9 Connector, Power Sync Connectors
If you’re using the Inhibit input signal on the rear panel INHIBIT/VOLTAGE MON
DB-9 connector and if this signal doesn’t power up the chassis, check the voltage that is being applied to the Inhibit signal. This signal is active low, meaning that a 0 VDC signal inhibits operation of the PSUs and the chassis is in
Standby mode. A logic high turns on the PSUs. Use a DMM to verify that the signal you’re providing to the Inhibit input on the DB-9 connector is truly switching between logic high and low.
Because there is an internal pull-up resistor on the Inhibit signal, an open circuit
(no signal connected) on the Inhibit signal will also turn on the power supply.
This means that, if the INHIBIT switch is set to the MAN position and if no signal is connected to the Inhibit input signal, the chassis will power up as soon as AC power is applied.
Power Sync and the two connectors are described in
“Multi-Chassis Power Sync” on page 114.

How does a Multi-Chassis System Differ from a MultiFrame System?
Multiple Chassis Operation
Multiple chassis systems require careful consideration of several factors, including:
– Host controller and chassis Power Sync (power-on and power-down considerations). This is the primary subject of this chapter.
– Time base and triggering for each chassis operates independent of the other chassis.
– PCIe connectivity between the host controller (either external or embedded) and the chassis ESM.
The M9506A ESM Thunderbolt 3 port does not support multiple chassis connections.
How does a Multi-Chassis System Differ from a MultiFrame System?
Keysight’s MultiFrame feature is not available on the M9506A
5-Slot AXIe Chassis. MultiFrame is supported on the Keysight
M9502A, M9505A, and M9514A AXIe chassis.
In both multi-chassis and MultiFrame systems, all chassis are controlled by a single controller. The differences between the two system types are:
In a multi-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 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.
Accordingly, there are two aspects of multiple chassis operation that need to be considered separately:
The first is the PCIe connectivity between the chassis and the host controller.
This is handled via PCIe cabling between the ESM modules. In practice, the potential combinations of instruments which can share synchronization and triggering are numerous. The only practical limit to the number of chassis you can connect is determined by the number of PCIe slots your host computer can enumerate.
Keysight M9506A 5-Slot AXIe Chassis User Guide 107
Multiple Chassis Operation How does a Multi-Chassis System Differ from a MultiFrame System?
The second is the synchronization and timing of clock and trigger signals between the AXIe chassis. Use MultiFrame chassis configurations to increase the number of measurement modules which use a common time base or cross triggering to achieve correlation.
Also:
The host PC’s 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 all 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. Please check the Keysight website at: PC Tested Configurations with PXIe/AXIe Chassis - Technical Overview for the latest updates to the product software, guides, data sheet and help files.
Always power up the last chassis in the series (subordinate 2 in the following diagrams), wait for its ESM’s Status light to stop blinking, then turn on the next chassis in the series and wait for its Status light to stop blinking. Finally turn on the Master Chassis. Wait for its Status light to stop blinking before turning on the Host PC.

Connect Multiple AXIe or PXIe Chassis to a Single Controller Multiple Chassis Operation
Connect Multiple AXIe or PXIe Chassis to a Single Controller
The Keysight Multiple PXIe and AXIe Chassis Configuration Tool helps you design a system consisting of up to four AXIe and PXIe chassis. These chassis may be connected to either an embedded controller (installed in the chassis) or an external PC connected by cable(s) to the chassis. The Multiple PXIe and AXIe
Chassis Configuration Tool allows you to interactively specify your system parameters, and then it designs a multi-chassis system according to your specifications. Once the design is presented, optionally select different components to further optimize the design to meet your specific requirements.
General Multi-Chassis Configurations
The following pages present six typical scenarios of multi-chassis operation. The first uses an external host controller with an M9049A Remote PC PCIe Host
Desktop Adapter to two M9506A chassis. The second shows PCIe connectors from the Master chassis ESM to the subordinate chassis ESM. The third configuration demonstrates the highest performance with two M9506A chassis connected to and external controller.The fourth example demonstrates the use of an embedded controller such as the Keysight M9537A. The M9536A Embedded
Controller is not supported for multiple chassis configurations.
All example configurations show multiple M9506A chassis. Other combinations are possible such as one M9506A Master chassis to a Keysight M9505A 5-slot or
M9502A 2-slot AXIe Subordinate chassis. The M9502A and M9505A chassis do not support daisy-chaining the PCIe connections. You can also connect PXIe chassis.
The Thunderbolt 3 connection does not support multiple chassis.

Connect Multiple AXIe or PXIe Chassis to a Single Controller Multiple Chassis Operation
External PC to Two Chassis Configuration
The most simple multi-chassis system consists of an external PC with a PCIe
Host Adapter card (such as the Keysight M9049A) connected to two PXIe or AXIe chassis. A PXIe chassis requires a System Module such as the Keysight M9022A.
An AXIe chassis does not require a system module interface, because a cable port is included in the ESM half height module. The link speed is determined by the chassis; for example, Gen 2 speed with the M9018 PXIe chassis or the
M9502A or M9505A AXIe chassis; Gen 3 speed is available with Gen 3 PXIe chassis such as the M9019A PXIe chassis or the M9506A AXIe chassis.

Multiple Chassis Operation Multi-Chassis Power Sync
Multi-Chassis Power Sync
Power Sync allows multi-chassis configurations to be powered on and off like a single chassis. A single power button push on any chassis turns on or off all chassis in the correct sequence. For example, with an embedded host controller,
Power Sync ensures that all downstream chassis are powered up before the embedded controller chassis is turned on. On power down, it ensures that the embedded controller chassis is turned off before all downstream chassis are turned off.
With an external host PC, Power Sync allows all chassis to be powered on or off by the external host automatically. When an external host is powered on, it prevents power button pushes on any chassis from turning off any chassis.

When multiple chassis are connected together in this way, pressing the power button on any chassis causes all connected chassis to power on. Pushing the power button on any connected chassis turns all other chassis off.
Up to four chassis may be connected together for the power sync feature to work.
Connect the cables only when all chassis are powered off to eliminate power mismatched states. If the chassis become out of sync, power all chassis down by holding the power button down for five seconds minimum. If that doesn’t work, remove AC power form all chassis and then restart the chassis.
These RJ45 connectors are for multi-chassis power-up synchronization only. Do not connect cables to a corporate or local LAN to these connectors.
In a multi-chassis system, the time base and triggering for each chassis operates independent of the other chassis. For more information, refer to Keysight's Multiple PXIe and AXIe Chassis

For Module Developers Module Types
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 to 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 could be designed to function in any two adjacent slots of the
M9506A.
– 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 For Module Developers
ATCA and AXIe Requirements
The Keysight AXIe (ATCA eXtensions for Instrumentation) chassis backplanes used in the M9506A 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 M9506A 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
AXIe modules must meet all ATCA mechanical requirements for modules.
Exception: AXIe 1.0 chassis do not accommodate rear transition modules
(RTM).
Hardware 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 M9506A 5-Slot AXIe Chassis User Guide 121
122
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. The following table provides a brief description of the timing interface signals:
Clock Signal Description
FCLK
CLK100
100 MHz PCIe Reference Clock
Functions as the chassis clock. Slot-to-Slot skew must be less than 100 pS.
SYNC
STRIG
Trigger/Clock synchronization signal. Slot-to-Slot skew must be less than 100 pS.
Direct connection for triggering between the system slot and instrument slots,
Less than 20 pS skew is allowed.
Exceptions:
– AXIe architecture expands the use of the ATCA Synchronization Clock
Interface. The signals and connector pin assignments for AXIe modules differ from ATCA.
Keysight M9506A 5-Slot AXIe Chassis User Guide
ATCA and AXIe Requirements For Module Developers
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.
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
“Clocks and Triggering” on page 84 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 88.
A 62 pair local bus for signaling between adjacent instrument slots.
The data transport fabric , Single Star x16 PCIe Gen 3 fabric:
– Channel 1 connects the ESM slot in a star configuration to provide an x16 link to each instrument slot
– Uses a distributed PCIe fabric reference clock (FCLK) driven from the
ESM
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.

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 For complete backplane photos, see
“M9506A Backplane” on page 124.
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.

The opening of covers or removal of parts is likely to expose dangerous voltages. Disconnect the product from all voltage sources while it is being opened.
If this product is not used as specified, the protection provided by the equipment could be impaired. This product must be used in a normal condition (in which all means for protection are intact) only.
These servicing instructions are for use by qualified personnel only. To avoid electrical shock, do not perform any servicing unless you are qualified to do so.
131
Troubleshooting and Service
To prevent electrical shock, disconnect the Keysight
Technologies Model M9506A from mains before cleaning. Use a dry cloth or one slightly dampened with water to clean the external case parts. Do not attempt to clean internally.
The detachable power cord is the instrument disconnecting device. It disconnects the mains circuits from the mains supply before other parts of the instrument. The front panel switch is only a standby switch and is not a LINE switch (disconnecting device).
The power cord is connected to internal capacitors that may remain live for 5 seconds after disconnecting the plug from its power supply.
If returning the chassis or any component of the chassis (for example, the ESM or a power supply module), use the original
Keysight packaging or compatible.

Updating the Chassis Firmware Troubleshooting and Service
Updating the Chassis Firmware
The current version of your chassis’ firmware is listed on the Home Page of the
web interface (see “Web Interface Home Page” on page 58). 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: www.keysight.com/find/M9506A , 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:
F6AX Identifies an M9506A 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. 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 version example:
F6AX-1.0.09-0007-A009-B0609-C05-UpdateFW
This example shows a chassis with firmware revision 1.0.09. The backplane revision is 0007 and component A is at revision 009, component B is at revision
0609 and component C is at revision 05. Refer to the M9506A AXIe Chassis
Firmware Update Guide for specific details regarding updating the chassis firmware.
Keysight M9506A 5-Slot AXIe Chassis User Guide 133
Troubleshooting and Service ESM and Chassis Self-Test
ESM and Chassis Self-Test
The ESM supports two types of self-test:
– Power-on Self-Test (POST) – This test happens on the Shelf Manager as soon as the chassis powers up. As noted, this type of self-test is referred to as “POST”.
– After-POST self-test – This test is initiated by the user either via the SFP or programmatically using the Self-Test IVI call:
KtMAXIeMon.Utility.SelfTest(“TestResult”,”TestMessage”); .
Unless noted otherwise, references to “self-test” always refers to the self test that is either initiated from the SFP or initiated programmatically. The phrase
“self-test” does not refer to POST.
The front panel Status LED shows the following LED states:
– OFF - standby
– Green (blinking) - ESM/Shelf Manager is booting up and waiting for modules to be ready for enumeration
– Green (solid) - power up complete and ready for enumeration
– Red - failure/service required.
The power on self-test (POST) routines are automatically executed at power on.
If POST passes, the status LED will be solid green. If POST fails, the status LED continues blinking green.
If POST passed (the Status LED is green), and then self-test is subsequently run and fails, the Status LED begins blinking green. Similarly, if POST failed (Status
LED blinking green), but then if self-test is subsequently run and passes, the
Status LED turns solid Green.
Regardless of what causes the Status LED to blink green (a POST failure or a failure during running of self-test), it will turn solid green again if Self-Test is run and passes.
Self-test runs a series of tests and any failure generates an error consisting of an error code ( TestResult ) and error message ( TestMessage ).
A single Self-Test error queue in the ESM holds both the power-on self-test errors and the user-initiated self-test errors. Power-on Self-Test error messages are identified by the “(POST)” prefix; user-initiated self-test messages do not have a prefix.
Running the user-initiated self-test (either from the Soft Front Panel or programmatically) preserves any unread power-on test messages in the queue, but erases any other (user-initiated) unread messages before running the tests.
You can use the Soft Front Panel or the IVI Self-TestErrorQuery call to view the errors.
134 Keysight M9506A 5-Slot AXIe Chassis User Guide
ESM and Chassis Self-Test Troubleshooting and Service
When you open the Soft Front Panel’s Self-Test dialog box, any previous results are automatically displayed. If you then click the Run Self-Test button, the new self-test results are displayed below any previous results.
Refer to
Chapter 8, Troubleshooting and Service on page 131 and
Self-Test Error Codes on page 149 for detailed information.
Refer to
“Self-Test Error Codes” on page 149 for a list of Error Codes.
Self-Test IVI-C Driver Calls
KtMAXIeTRIG.Utility.SelfTest or KtMAXIeMON.Utility.SelfTest performs an instrument self test, waits for it to complete, and queries the instrument for any results.

Troubleshooting and Service Troubleshooting
Troubleshooting
The Keysight M9506A 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 or PXIe 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, the AXIe chassis has three major subsystems that can be replaced:
Fan Trays
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 trays,
PSU, and ESM replacement.

Troubleshooting Troubleshooting and Service
Chassis Inhibit/Voltage Monitoring
The method of powering up the chassis depends on the position of the INHIBIT rear panel switch, which can be set to the DEF (DEFault) position or to the MAN
(MANual) position). These two methods work as follows:
– INHIBIT switch in the DEF position — In this position, the front panel power push button is used to switch the chassis between ON and
Standby—hence, this push button is known as the ON/Standby push button.
– INHIBIT switch in the MAN position — In this position, the Inhibit signal (pin 5 on the rear panel DB-9 connector) controls chassis power. The chassis is powered up by applying a logic high signal to the Inhibit pin. When the
Inhibit pin (pin 5) is pulled low, the chassis is in Standby.
Chassis Inhibit Switch
DB9 Connector for measuring
PSU voltage rails
Figure 42 Chassis Power Inhibit Switch, DB9 Connector, Power Sync Connectors
Keysight recommends leaving the INHIBIT switch in the DEF position when connecting the AC power cord to the chassis. After inserting the power AC power cord, then move the INHIBIT switch to the MAN position.
The RJ45 connectors are for multi-chassis power-up synchronization. Do not connect LAN cables to these connectors and to your corporate LAN. Refer to
“Multi-Chassis Power Sync” on page 114 for detailed information.
If you’re using the Inhibit input signal on the rear panel INHIBIT/VOLTAGE MON
DB-9 connector and if this signal doesn’t power up the chassis, check the voltage that is being applied to the Inhibit signal. This signal is active low, meaning that a 0 VDC signal inhibits operation of the PSUs and the chassis is in
Keysight M9506A 5-Slot AXIe Chassis User Guide 137
138
Troubleshooting and Service Troubleshooting
Standby mode. A logic high turns on the PSUs. Use a DMM to verify that the signal you’re providing to the Inhibit input on the DB-9 connector is truly switching between logic high and low.
Because there is an internal pull-up resistor on the Inhibit signal, an open circuit
(no signal connected) on the Inhibit signal will also turn on the power supply.
This means that, if the INHIBIT switch is set to the MAN position and if no signal is connected to the Inhibit input signal, the chassis will power up as soon as AC power is applied.
Measuring the Voltage Rails
The two power supply voltage rails (3.3V and –48V) can be measured on the
DB-9 connector on the chassis rear panel using a digital multi-meter. Each voltage rail contains a current limiting resistor to prevent accidentally shorting the supplies during measurements.The two power supply rails should be within
±5% of their nominal values. Keysight recommends checking the power rails at least yearly using the chassis soft front panel (SFP) or programmatically. In addition, the power rails are accessible on the rear panel DB-9 connector, and can be checked with a DMM.
The PSUs contain no customer-serviceable parts such as fuses. If a PSU fails, it must be replaced as a complete unit. Replacement of the power supply is described in
No operator serviceable parts inside. Refer servicing to qualified personnel. To prevent electrical shock, do not remove covers.
Servicing instructions are for use by qualified personnel only. To avoid electrical shock, do not perform any servicing unless you are qualified to do so.
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:
Power switch (on the ESM, mechanical feel and status indicator light)
Rear panel circuit breaker (mechanical feel and resulting relay activation)
PSU fan operation
Chassis fan operation

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.
ON: Press the ON/STANDBY switch (turn the chassis ON). You should observe:
– Momentarily press the power switch and status indicator will light.
– The PSU fans will increase to and remain at high speed.
– The ESM front panel STATUS light will cycle as follows:
– Flashing green - ESM is booting; for about 20 seconds
– Flashing green - briefly
4
– Steady green - booted
– Steady red - the ESM has detected failure and requires service.
STANDBY: Press the ON/STANDBY switch again. You should observe:
– Monitor the status light, it should 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.

5 OFF: Open the circuit breaker (OFF). You should observe:
– 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 PSU fans will turn off.
Chassis Hardware Troubleshooting
Chassis Fans
The M9506A AXIe chassis has two fan trays, one on the left and one on the right, of the chassis. The left Fan tray has six fans providing air to the chassis slots and one fan for the Zone 3 area. The right fan tray has six fans. These fans are observable from outside the chassis by looking in the side vents. Additionally, the power supply has one fan. Refer to
Chapter 3, Navigating the Web Interface on page 55 for information on determining the fan speed.
If module loads are kept within the 300 W 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
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.

2
Visually check that all chassis fans are turning. Visually inspect both the PSU and chassis fans through the side of the chassis. 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 146
), and recheck. If any fans still do not turn, replace the fan tray.
Using the Web Interface, access the Fan Control page.
Keysight M9506A 5-Slot AXIe Chassis User Guide

-- All fan speeds should be about the same. Visually identify any that turn more slowly than the group. Any large deviation may indicate reveal early signs of fan failure.
-- You may set a higher fan speed to see if the fans are responsive.
For fan noise problems, identify which fans are noisy or not turning properly by visually inspecting both the PSU and chassis fans through the side of the chassis.
For all routine chassis fan failures, replace the fan tray assembly (see
Replace the Fan Trays” on page 146). For PSU fan failures, replace the PSU
(see
“To Replace the Power Supply Unit” on page 144).
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 shut themselves down (or not power up at all) if they are out of spec.
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 144).
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 148).
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.
All but one of these switches are reserved for factory testing purposes or reserved for future use and should not be changed.
The only exception is SW56 which is used to configure the PCIe settings as shown in the following table.

Self-Test Error Codes
Keysight’s M9506A AXIe chassis can run a series of self-tests to indicate that the hardware is functioning normally. The self-tests are run automatically when the chassis is powered on and may be invoked via IVI function calls (see the IVI-C and IVI .NET help files), the chassis web page, or from the chassis Soft Front
Panel interface).
You should access the appropriate web page and/or the Soft Front Panel interface to get a list of pass/failed error codes.

GbE
Gigabit Ethernet. Ethernet at a rate of 1 gigabit per second.
GUID
globally unique identifier is a unique identifier number used in computer software.The term GUID also is used for Microsoft's implementation of the
Universally Unique IDentifier (UUID). The value of a GUID is represented as a
32-character hexadecimal string, and is usually stored as a 128-bit integer
HPM
Hardware Platform Management. PICMG specification that defines an open mechanism to upgrade the resident management software and firmware.
IPMB
Intelligent Platform Management Bus. Based on the I

KCS
Keyboard Style Controller
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.
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 line at: www.keysight.com/find/pxie-multichassis .
