Chapter 1. Reference Information
This chapter provides reference information for the D10 and D20 I/O subsystems.
D10 Overview
The D10 is a 19-inch, rack-mountable I/O subsystem that is attached to a processor subsystem drawer to
extend the system’s capacity for I/O adapters. The I/O drawer includes redundant concurrently
maintainable power and cooling.
Five PCI-X slots and one PCI slot are available for PCI adapters. PCI adapters are installed through the
rear of the I/O subsystem using PCI adapter cassettes. Because the PCI slots support hot-pluggable
adapters, the I/O subsystem can have adapters installed without turning off power or removing covers. The
D10 is 4 EIA units high. Two D10s can be installed side-by-side in a 19-inch rack enclosure.

D10 Operator Indicators
LEDs are used on the D10 as operator indicators. Tables found in “I/O Subsystem PCI-X Slot LED
Definitions” and “D10 Power” on page 4 describes the LED states and their definitions. For more
information on LEDs and their definitions, see Chapter 5, “Fault and Attention LEDs”, on page 169. LEDs
can be found on or near the following FRUs:
v LED indicators visible on each PCI adapter cassette
v LED indicators on the I/O subsystem backplane
v Attention/Identify LEDs for power supplies and fans
D10 PCI-X Slots
The D10 has five PCI-X slots and one PCI slot. Adapters are installed and removed using a PCI adapter
cassette, which allows adapters to be installed without turning off the power or opening the I/O subsystem
covers.
PCI adapters are installed using an adapter cassette, each adapter cassette shows two LEDs for each
adapter. There is a green power indicator LED (upper) and an amber fault/identify LED (lower). The slots
are numbered on the rear of the chassis from left to right 1 through 6. Slot 1 is a 5V PCI slot. Slots 2
through 6 are 3.3V PCI-X.
I/O Subsystem PCI-X Slot LED Definitions
The green and amber LEDs (viewed on the rear of the PCI adapter cassette when installed) are used to
indicate the state of the PCI slot during removal and replacement of an adapter. The following table

D10 Power
The following figure shows the front view of the pocessor subsystem and two I/O subsystems. Each unit
has two power supplies and two power cords for redundancy. Connect the power cords from one side of
the system to one power distribution bus in the rack. Connect the power cords from the other side of the
system to a different power distribution bus in the rack. To ensure that the systems in a rack keep running
if power is interrupted, a separate branch power line for each side of the rack must be used.

Subsystem Positioning and Cabling
I/O subsystems can be installed in a standard 19-inch EIA rack in any location. The cables that connect
the subsystems allow some flexibility in drawer placement, but the I/O subsystems should be located
above the processor subsystem to which they are connected in the same rack.
Up to eight I/O subsystems can be connected to a processor subsystem. Use the following guidelines:
v Each I/O subsystem connects to the processor subsystem using one system power control network
(SPCN) cable loop.
v Each I/O subsystem connects to the processor subsystem using one or more remote I/O (RIO) cable
loops.
v Lowest cost configurations allow up to four I/O subsystems connected to the processor subsystem using
a single RIO loop.
v Optimum performance is achieved when each I/O drawer is connected to the processor subsystem
through its own RIO loop.
SPCN Cabling
I/O subsystem SPCN cables are connected to the processor subsystem unit in a loop configuration. The
SPCN cables are connected in a loop so that the system has two paths to each I/O subsystem. Up to
eight I/O subsystems are supported on one SPCN loop.
One I/O Subsystem, Two I/O Subsystems: The illustrations on the left show one I/O subsystem
connected to the processor subsystem. The illustrations on the right show two I/O subsystems connected
to the processor subsystem using one SPCN loop.

subsystems connected to the processor subsystem using one SPCN loop.
Processor Subsystem Connected to Four or Eight D10 I/O Subsystems:
1 Processor Subsystem
2 I/O Subsystem
RIO Cabling
I/O subsystems are connected to the processor subsystem through remote I/O (RIO) cable loops. The
cable loops are connected to ports that are on the rear of the processor subsystem. The RIO cables are
connected in loops so that the system has two paths to each I/O subsystem when more than one I/O
drawer is in a loop.
If only one I/O subsystem is in a RIO loop and both the processor subsystem and the I/O subsystem are
RIO-2 capable, the RIO-2 cables are used as one two-cable path to the I/O subsystem. In this cable
configuration, the data rate is increased by a factor of 2.
v A maximum of eight D10 drawers are supported on one processor subsystem.
v If both D10 I/O drawers are connected to the same processor subsystem, the total number of I/O
subsystems supported is eight.
v The maximum number of I/O subsystems supported on one RIO loop is four.
v The D10 I/O drawers must be on separate RIO loops.
v The D10 with RIO cabling and D10 with RIO-2 cabling can share one RIO loop.
The system can have up to four RIO loops. A total of eight I/O drawers can be connected to the processor
subsystem in a variety of cabling configurations. For optimum performance, connect the RIO loops in a
configuration that distributes multiple I/O drawers among as many RIO loops as possible. A dedicated RIO
loop for each I/O drawer can provide optimum performance. Some examples of valid cabling examples
follow.

D10 Location Codes
This system (processor subsystem and attached I/O subsystems) use physical location codes in
conjunction with AIX location codes to provide mapping of failing field replaceable units (FRUs). The
location codes are produced by the processor subsystem’s firmware and AIX. For information about how to
read a location code, see the service guide for the processor subsystem to which your I/O subsystem is
connected.
AIX and Physical Location Code Table
This section covers the AIX and Physical Location Code tables for the D10.
The tables in this section contain the location codes for I/O subsystems when they are attached to the
system unit. In the tables, the location code for the I/O subsystem number is represented by dd. The first
time that an installed system is powered on, the I/O subsystems are numbered. For example, if a system
is first powered on with eight I/O subsystems connected, the dd value for the subsystems should be
numbered from 2 through 9.
Note: If the system was powered on with I/O subsystems connected before delivery to the customer, the
I/O subsystem location codes for the connected I/O subsystems are permanently set.
If at a later time, an I/O subsystem is removed from the system and a different I/O subsystem is
substituted, the substitute is assigned the next higher number available for its value of dd, which in the
earlier example, is 10. If the original I/O subsystem is reinstalled in the system configuration, the system
uses the original dd value for the I/O subsystem.
To keep the system from renumbering the I/O drawer when an I/O backplane is replaced, the VPD module
from the old I/O backplane must be moved over to the new I/O backplane.
The following diagram defines each part of a location code.
Ux.dd-xx-yy
| | | |
| | | |
| | | yy This code is used for the next component (yy, yy, yy, ...)
| | xx This code is used for the next component (Px, Fx, Vx, ...)
| dd This code is the location code for the I/O drawer (2 to 63)
Ux This code normally identifies the rack in which a drawer is installed.
The x will always be zero (0) for this system.

D20 Overview
The D20 is a 19-inch, rack-mountable I/O subsystem that is attached to a processor subsystem to extend
the system’s capacity for I/O adapters and disk drives. The I/O subsystem includes redundant concurrently
maintainable power and cooling.
Seven PCI slots are available for PCI adapters. Because the PCI slots support hot-pluggable adapters, the
I/O subsystem can have adapters installed without turning off power. The D20 is 4 EIA units high and is
compatible with 19-inch EIA rack enclosures.
D20 I/O Subsystem Features
The features of the D20 enable this I/O subsystem to extend the input and output capabilities of the
processor subsystem. Features such as PCI-X adapters and internal SCSI disk drives are supported.
D20 Operator Indicators
LEDs are used on the D20 as operator indicators. Tables found in “D20 PCI-X Slots” and “D20 Power” on
page 18 describes the LED states and their definitions. For more information on LEDs and their definitions,
see Chapter 5, “Fault and Attention LEDs”, on page 169. LEDs can be found on or near the following

D20 Power
The D20 is standard with one power supply. If the customer wants redundant power in their I/O
subsystem, an optional power supply can be ordered. Either power supply, in a D20 that is configured with
two power supplies, can provide the necessary voltages and currents, independent of the other power
supply. The left and right power-supply output voltages are connected and monitored by the power
distribution board contained in the I/O subsystem.
The left and right power supplies are hot-pluggable and may be changed one at a time while the system is
operational. Each power supply is capable of converting available 110/220 V ac to the proper internal
voltages used by the system components. The internal voltage range is 5 volts system standby, 3.3 volts,
5 volts, 12 volts and -12 volts. When operating correctly, each supply will share the current load when
powered on. When in a fault state, the operating power supply will supply standby current to the faulted
supply for the DEVROS module. The following table describes power-related LED indicators that are
available on the D20. The operator panel LED referred to in the following table is on the front of the
processor subsystem to which the I/O subsystem is attached.

D20 Cooling
Four blowers are mounted on the top of the I/O subsystem to provide cooling.
Attention: The four cooling blowers mounted on top of the D20 are hot-plug. The one exception is when
your subsystem has only one power supply either installed or functioning, in which case you must shut
down the system and subsystem. Failure to do so will automatically shut down the system.
D20 Input/Output Ports
The connector ports on the rear of the D20 I/O subsystem are used to connect the RIO-2 cables, the
SPCN cables, and the rack-beacon LED.

D10 and D20 Service Guide
Cabling the D20 to a 286/C4
The D20 subsystem can be installed in any location in a standard 19-inch EIA rack. The cables that
connect the subsystems allow some flexibility in drawer placement. Up to two D20s can be connected to a
286/C4. Each I/O subsystem is connected to the processor subsystem using a system power control
network (SPCN) cable loop and a remote I/O (RIO) cable loop. One SPCN cable loop is needed to
connect the I/O subsystems to one processor subsystem.
Before connecting the RIO-2 and SPCN cables to the D20, do the following:
1. Ensure that your 286/C4 is running the latest level firmware. Refer to the ″Firmware Updates″ section
of the ″Using the Service Processor″ chapter in the 286/C4 and 286/E4 Service Guide, order number
SA23-1277. For information about checking or upgrading the firmware level of your 286/C4.
2. After ensuring that your firmware is at the latest level, turn off the power and disconnect the 286/C4
power cables from the power source.
3. Attach the RIO-2 and SPCN cables. For cabling diagrams, see “RIO-2 (Remote Input Output) Cabling”
on page 26.
4. After connecting the RIO-2 and SPCN cables from the D20 to your system, reconnect the system’s
power cables to the power source and refer to “Stopping and Starting the System” on page 42.
5. Run system verification. Refer to the ″Verifying the Hardware″ chapter in the 286/C4 and 286/E4
Installation Guide, order number SA23-1277.
Your 286/C4 is expandable when connected up to two D20 I/O drawers. Each D20 can contain up to 7 I/O
PCI adapter slots, and two 6-pack disk drive (DASD) bays.
Chapter 1. Reference Information
25
RIO-2 (Remote Input Output) Cabling
The following rules apply to RIO-2 cable connections:
Notes:
1. To connect to a D20, you will be using the RIO-2 (Remote Input Output) and SPCN (System Power
Control Network) connectors and cables. The RIO-2 and SPCN cables provide two functions, remote
data bus connection, and power control.
2. The I/O drawers must be connected in a loop for both the RIO-2 and SPCN cables. The loop
connection provides redundant paths so that if a failure occurs in part of a cable, the system will
continue to operate. If a failure does occur, a message is displayed on the system console; however,
the system does continue to operate. See the following illustrations for possible cabling configurations.
To connect the RIO-2 cables to the rear of the 286/C4, do the following:
1. Locate the RIO-2 cable-support bracket.
2. Using two M3 x 6 retaining screws, secure the RIO-2 cable-support bracket to the rear of the 286/C4
chassis. See the following illustration.
1 286/C4
2 RIO-2 Cable-Support Bracket
3 M3 x 6 Retaining Screws (Quantity 2)
3. Pull the sliding portion of the RIO-2 cable-support bracket back from the 286/C4 chassis. The sliding
portion of the cable support bracket will stop before being fully separated.
4. Align the RIO-2 cable connector with the bottom of the sliding portion of the RIO-2 cable support
bracket.

D20 Location Codes
This system (processor subsystem and attached I/O subsystems) uses physical location codes in
conjunction with AIX location codes to provide mapping of a failing field replaceable units (FRUs). The
location codes are produced by the processor subsystem’s firmware and AIX. For information about how to
read a location code, see the service guide for the processor subsystem to which your I/O subsystem is
connected.
AIX and Physical Location Code Table
This section covers the AIX and Physical Location Code tables for the D20 I/O subsystem.
The tables in this section contain the location codes for I/O subsystems when they are attached to the
system unit. In the tables, the location code for the I/O subsystem number is represented by dd. The first
time that an installed system is powered on, the I/O subsystems are numbered. For example, if a system
is first powered on with two I/O subsystems connected, then the dd value for the connected I/O
subsystems should be numbered from 2 and 3.
Note: If the system was powered on with I/O subsystems connected before delivery to the customer, the
I/O subsystem location codes for the drawers connected at that time are already assigned.
If at a later time, an I/O subsystem is removed from the system and a different I/O subsystem is
substituted, the substitute is assigned the next higher number available for its value of dd, which, in the
earlier example, is 4. If the original I/O subsystem is reinstalled in the system configuration, the system
uses the original dd value for the I/O subsystem.
To keep the system from renumbering the I/O drawer when an I/O backplane is replaced, the VPD module
from the old I/O backplane must be moved over to the new I/O backplane.
The following diagram defines each part of a location code.
Ux.dd-xx-yy
| | | |
| | | |
| | | yy This code is used for the next component (yy, yy, yy, ...)
| | xx This code is used for the next component (Px, Fx, Vx, ...)
| dd This code is the location code for the I/O drawer (2 to 63)
Ux This code normally identifies the rack in which a drawer is installed.
The x will always be zero (0) for this system.

Powering the System On and Off
Power for the I/O subsystems is controlled by the attached processor subsystem and the System Power
Control Network (SPCN).
For information about procedures to power the system on and off, refer to the service guide of the
processor subsystem to which the I/O subsystem is attached.
Power-On Self-Test
After power is turned on and before the operating system is loaded, the system does a power-on self-test
(POST). The RIO loop that connects the I/O subsystems to the system unit is tested. Tests are also
performed on the installed adapters and devices in the I/O subsystems. If an error occurs during the
POST, an error code is displayed on the system operator panel LCD that indicates which part is failing and
which subsystem contains the error.

D10 and D20 Service Guide
Chapter 2. Diagnostics and Maintenance Procedures
The system uses an integrated set of software diagnostic procedures to help isolate failing components
and system maintenance. This book, along with the Diagnostic Information for Multiple Bus Systems, is the
basis of the diagnostic procedures. Refer to the system service guide when running diagnostics on your
I/O subsystem.
Power and Attention LEDs
The Power and Attention LEDs provide a means to identify failing components in your subsystem. When a
failing component is detected in your system, the system’s Attention LED is turned on.
Component LEDs
To further help you identify the failing component, all system components have individual LEDs that
indicate a failure when lit. The LEDs are either on the component itself or on the carrier of the component
(memory card, fan, memory module, or CPU).
The LEDs are either green or amber in color. A lit green LED indicates that the system or component is
receiving power. A lit amber LED identifies a system or component on the system. The amber LED can
also indicate when a system or component on a system has a problem or fault. For more information on
LEDs and their definitions, see Chapter 5, “Fault and Attention LEDs”, on page 169.
Resetting the LEDs
To reset the LEDs, do the following:
1. Replace the failing component with the new component.
2. Log in as root user.
3. At the command line, type diag.
4. Select Task Selection.
5. Select Log Repair Action.
6. Select the device that was repaired. (If the device is not listed, select sysplanar0.)
Checkpoints
The system uses various types of checkpoints, error codes, and SRNs, which are referred to throughout
your system’s service guide. These codes can appear in the service processor boot progress log, the AIX
error log, and the operator panel display. Understanding the definition and relationships of these codes is
important to the service personnel who are installing or maintaining the system.
Service Request Numbers (SRNs) are listed in the Diagnostic Information for Multiple Bus Systems, order
number SA23-2769.
FRU Isolation
For a list of error codes and recommended actions for each code, see your system’s service guide. These
actions can refer to Chapter 4, “Parts Information”, on page 157, “Maintenance Analysis Procedures
(MAPs)” on page 40, or provide informational message and directions. If a replacement part is indicated,
direct reference is made to the part name. The respective AIX and physical location codes are listed for
each occurrence as required. For a list of locations codes, see your system’s service guide.
39
Maintenance Analysis Procedures (MAPs)
The maintenance analysis procedures (MAPs) provide the service representative a step-by-step procedure
to analyze a problem with the system and I/O subsystem hardware. Be prepared to record code numbers
and other data while using the MAPs.
Because the D10 and D20 are subsystems, refer to your system’s service guide. The system’s service
guide contains all of the MAPs needed for servicing the D10 and D20 I/O subsystems.
Checkpoints
Checkpoints display on the system operator panel and the virtual terminal while the system unit is
powering on and going through the initial program load (IPL). See the system’s service guide for
descriptive information and a complete listing of all checkpoints used by the D10 and D20 I/O subsystems.
Error Code to FRU Index
The Error Code to FRU Index lists fault symptoms and possible causes. The most likely cause is listed
first. Use this index to help you decide which FRUs to replace when servicing the D10 or D20 I/O
subsystem. See your system’s service guide for more information and a complete listing of all error codes
and FRUs used by the D10 and D20 I/O subsystem.
Using the Service Processor
The service processor is in the processor subsystem to which your I/O subsystem is connected and runs
on its own power boundary. The service processor continually monitors hardware attributes and the
environmental conditions within the system and connected I/O subsystems. The service processor is
controlled by firmware and does not require the operating system to be operational to perform its tasks.
The service processor menus allow you to configure service processor options, as well as enable and
disable functions.
Service processor menus are available using an ASCII terminal or an HMC virtual terminal window when
OK is displayed on the operator panel or when the service processor has detected a system problem (such
as a surveillance failure).
For more information about the service processor for the system to which your I/O subsystem is
connected, see the system’s service guide.
Using System Management Services
Use the system management services menus to view information about the processor subsystem to which
the I/O subsystem is connected. For more information about the service processor, see the service guide
for the attached system.

D10 and D20 Service Guide
Chapter 3. Removal and Replacement Procedures
Before performing any of the removal or replacement procedures in this chapter, read the following danger
and caution notices.
Safety Considerations
Observe the following safety precautions anytime you work with these I/O subsystems.
For the I/O subsystem you are about to setup or service:
v The ac power interface connector is considered the main power disconnect device.
v The I/O subsystems have independent redundant power supply capabilities, meaning that each unit
might be configured to have two power supplies running simultaneously in the same I/O subsystem.
When instructed to disconnect the power source, ensure that all power cables that run to each serviced
subsystem are disconnected from the power distribution bus.
DANGER
An electrical outlet that is not correctly wired could place hazardous voltage on metal parts of
the system or the devices that attach to the system. It is the responsibility of the customer to
ensure that the outlet is correctly wired and grounded to prevent an electrical shock.
Before installing or removing signal cables, ensure that the power cables for the system unit
and all attached devices are unplugged.
When adding or removing any additional devices to or from the system, ensure that the power
cables for those devices are unplugged before the signal cables are connected. If possible,
disconnect all power cables from the existing system before you add a device.
Use one hand, when possible, to connect or disconnect signal cables to prevent a possible
shock from touching two surfaces with different electrical potentials.
During an electrical storm, do not connect cables for display stations, printers, telephones, or
station protectors for communications lines.
D05
CAUTION:
This product is equipped with a three-wire power cable and plug for the user’s safety. Use this
power cable with a properly grounded electrical outlet to avoid electrical shock.
C01
CAUTION:
This unit has more than one power supply cord. To reduce the risk of electrical shock, disconnect
two power supply cords before servicing.
C21
41
Handling Static-Sensitive Devices
Attention: Electronic boards and disk drives are sensitive to static electricity discharge. These devices
are wrapped in antistatic bags to prevent this damage.
Take the following precautions:
v If you have an antistatic wrist strap available, use it while handling the device.
v Do not remove the device from the antistatic bag until you are ready to install the device in the system.
v With the device still in its antistatic bag, touch it to a metal frame of the system.
v Grasp cards and boards by the edges. Hold drives by the frame. Avoid touching the solder joints or
pins.
v If you need to lay the device down while it is out of the antistatic bag, lay it on the antistatic bag. Before
picking it up again, touch the antistatic bag and the metal frame of the system at the same time.
v Handle the devices carefully to prevent permanent damage.
Stopping and Starting the System
For procedures to power the system on and off, refer to the service guide of the processor subsystem to
which the I/O subsystem is attached.

PCI Hot-Plug Manager Access
Attention: The Linux operating system does not support these hot-plug procedures. Also, Linux does not
support hot-plugging any hot-pluggable PCI adapters. Systems with Linux installed on one or more
partitions must be shut down and powered off before replacing any PCI adapter assigned to a Linux
partition. Follow the non-hot-pluggable adapter procedures when replacing a PCI adapter in any partition
with Linux installed.
The installation instructions for hot-pluggable PCI adapters refer you to these procedures when it is
appropriate to perform them.
Note: A PCI adapter is only hot-pluggable if the PCI adapter supports hot-plug applications. See the PCI
Adapter Placement Reference, order number SA23-2504.
Accessing Hot-Plug Management Functions
Note: Removing or installing a Hot-Pluggable PCI adapter requires the system administrator to take the
PCI adapter offline prior to performing the operation. Before taking an adapter offline, the devices
attached to the adapter must be taken offline as well. This action prevents a service representative
or user from causing an unexpected outage for system users.
For additional information about taking an adapter offline or removing it from the system
configuration, see the AIX System Management Guide: Operating System and Devices.
To access the hot-plug menus, do the following:
1. Log in as root user. If the system is a partitioned system, log in as root user on the partition that has
the adapter assigned to it.
2. At the command line, type smitty.
3. Select Devices.
4. Select PCI Hot Plug Manager and press Enter.
5. The PCI Hot-Plug Manager menu displays. Return to the procedure that directed you here. For a
description of the menu options, see below.

adapter in that slot.
Add a PCI Hot-Plug Adapter
Allows the user to add a new PCI hot-plug-capable adapter to the slot with the system turned on. You will
be asked to identify the PCI slot that you have selected prior to the actual operation. The selected PCI slot
will go into the Action state and finally into the On state.
Note: The system will indicate the slot holds an “Unknown” device until you perform the Install/Configure
Devices Added After IPL option to configure the adapter.
Replace/Remove a PCI Hot-Plug Adapter
Allows the user to remove an existing adapter, or replace an existing adapter with an identical one. For
this option to work, the adapter must be in the Defined state (see “Unconfigure a Device” option below).
You will be asked to identify the PCI slot prior to the actual operation. The selected PCI slot will go into the
Action state.
Identify a PCI Hot-Plug Slot
Allows the user to identify a PCI slot. The selected PCI slot will go into the Identify state. See “I/O
Subsystem PCI-X Slot LED Definitions” on page 2.
Unconfigure a Device
Allows the user to put an existing PCI adapter into the Defined state if the device is no longer in use.
This step must be completed successfully before starting any removal or replacement operation. If this
step fails, the customer must take action to release the device.

D10 and D20 Service Guide
Install/Configure Devices Added After IPL
The system attempts to configure any new devices and tries to find and install any required software from
a user-selected source.
The add, remove, and replace functions return information to the user indicating whether the operation
was successful. If additional instructions are provided on the screen, complete the recommended actions.
If the instructions do not resolve the problem, see the following:
v If the adapter is listed as Unknown, perform the Install/Configure Devices Added After IPL option to
configure the adapter.
v If you receive a warning indicating that needed device packages are not installed, the system
administrator must install the specified packages before you can configure or diagnose the adapter.
v If you receive a failure message indicating a hardware error, the problem might be either the adapter or
the PCI slot. Isolate the problem by retrying the operation in a different PCI slot, or trying a different
adapter in the slot. If you determine that you have failing hardware, call your service representative.

Hot-Swap Blower Replacement
Note: If a blower assembly is being replaced for a redundant failure, after the service repair action is
completed, ask the customer to check the crontab file for any power/cooling warning messages.
When a power or cooling error is encountered, AIX adds an entry to the crontab file to ″wall″ a
warning message every 12 hours, to alert or remind the customer of the problem. Replacing the
faulty part does not clear this crontab entry, so unless the crontab file is edited to remove this
entry, the customer continues to be reminded of the failure despite its having been repaired. The
crontab -l command reads the crontab file to determine if an entry exists. The crontab -e
command edits the file.
To replace a hot-swap blower, do the following:
1. Grasp the blower by its snap button, and ensure that the snap button is in the unlocked position.
Note: Snap buttons are in the unlocked position when the button component is pulled back as far as

Note: A PCI adapter is only hot-pluggable if the PCI adapter is supported for hot-plug applications. For
complete information regarding your PCI adapter, see the PCI Adapter Placement Reference, order
number SA23-2504.
Accessing Hot-Plug Management Functions:
Note: Removing or installing a hot-pluggable PCI adapter requires the system administrator to take the
PCI adapter offline prior to performing the operation. Before taking an adapter offline, the devices
attached to the adapter must be taken offline as well. This action prevents a service representative
or user from causing an unexpected outage for system users.
For additional information about taking an adapter offline or removing it from the system
configuration, see the AIX System Management Guide: Operating System and Devices.
This publication is also contained on the AIX Documentation CD. The documentation is made

Unconfigure a Device
Allows the user to put an existing PCI adapter into the Defined state if the device is no longer in use.
This step must be completed successfully before starting any removal or replacement operation. If this
step fails, the customer must take action to release the device.
Configure a Defined Device
Allows a new PCI adapter to be configured into the system if software support is already available for the
adapter. The selected PCI slot will go into the On state.
Install/Configure Devices Added After IPL
The system attempts to configure any new devices and tries to find and install any required software from
a user-selected source.
The add, remove, and replace functions return information to the user indicating whether the operation
was successful. If additional instructions are provided on the screen, complete the recommended actions.
If the instructions do not resolve the problem, do the following:
v If the adapter is listed as Unknown, perform the Install/Configure Devices Added After IPL option to
configure the adapter.
v If you receive a warning indicating that needed device packages are not installed, the system
administrator must install the specified packages before you can configure or diagnose the adapter.
v If you receive a failure message indicating a hardware error, the problem might be either the adapter or
the PCI slot. Isolate the problem by retrying the operation in a different PCI slot, or trying a different
adapter in the slot. If you determine that you have failing hardware, call your service representative.
v Do not use Install/Configure Devices Added After IPL if your system is set up to run HACMP
clustering. Consult with your system administrator or software support to determine the correct method
to configure the replacement device.

D20 Power Supplies
DANGER
Do not attempt to open the covers of the power supply. Power supplies are not serviceable and
are to be replaced as a unit.
D02
The D20 subsystem has power supplies that have hot-swap capabilities. To use this feature, you must
have two power supplies in place.
Power Supply Removal
D20 subsystems configured at the factory with one power supply have a power supply filler panel. The
filler panel protects the vacant power supply connector from dust or damage. If you plan to remove one of
the power supplies from a subsystem configured with two power supplies, obtain the power supply filler
panel. The part number for the power supply filler panel is 53P0233.
Note: You need not shut down the system to change a subsystem power supply.
Before performing any of the following procedure, read and understand all of the safety notices beginning
with “Safety Considerations” on page 41.
To remove a power supply from your subsystem, do the following:
1. Put the subsystem into the service position as described in “D20 Service Position” on page 109.
2. Open the service access cover as described in “D20 Service Access Cover” on page 111.
3. If your subsystem is configured with two power supplies, visually check the power supply LEDs. If one
of the power supplies has an amber LED that is lit or blinking, suspect that power supply to be faulty.
4. Remove the power cable from the rear of the power supply. Wait at least 10 seconds before
performing the next step.
5. Release, and then lift the power supply handles.
6. Lift the handles until they are perpendicular (90 degrees) to the top of the power supply. By placing the
handles perpendicular to the top of the power supply, the base or hinged portion of each handle acts
as a cam and will gently pry the power supply from its docking connector located on the subsystem
system board.

Chapter 5. Fault and Attention LEDs
This chapter contains information about fault and attention LEDs, which assist in identifying failing
components in your system.
Component LEDs
Individual LEDs are located on or near the failing components. The LEDs are located either on the
component itself or on the carrier of the component (for example, PCI adapters and disk drives). LEDs are
either green or amber.
Green LEDs indicate one of two things:
v Electrical power is present.
v Activity is occuring on a link. (The system could be sending or receiving information.)
Amber-colored LEDs indicate a fault or identify condition. If your system or one of the components on your
system has an amber-colored LED turned on or blinking, identify the problem and take the appropriate
action to restore the system to normal.
The following table identifies the location, color and status of your system component LEDs.
