Chapter 3. Installing options
This chapter provides detailed instructions for installing hardware options in the
server.
Installation guidelines
Before you begin installing options in the server, read the following information:
v For a list of supported options for the server, go to http://www.ibm.com/us/
compat/.
v Read the safety information beginning on page v and the guidelines in “Handling
static-sensitive devices” on page 12. This information will help you work safely
with the server and options.
v Make sure that you have an adequate number of properly grounded electrical
outlets for the server, monitor, and other devices.
v Back up all important data before you make changes to disk drives.
v Have a small flat-blade screwdriver available.
v Yo u do not have to turn off the server to install or replace hot-swap power
supplies, hot-swap fans, or hot-plug Universal Serial Bus (USB) devices.
v Blue on a component indicates touch points, where you can grip the component
to remove it from or install it in the server, open or close a latch, and so on.
v Orange on a component or an orange label on or near a component indicates
that the component can be hot-swapped, which means that if the server and
operating system support hot-swap capability, you can remove or install the
component while the server is running. (Orange can also indicate touch points on
hot-swap components.) See the instructions for removing or installing a specific
hot-swap component for any additional procedures that you might have to
perform before you remove or install the component.
v When you need to access the inside of the server, you might find it easier to lay
the server on its side.
System reliability guidelines
To help ensure proper cooling and system reliability, make sure that:
v Each of the drive bays has a drive or a filler panel and electromagnetic
compatibility (EMC) shield installed in it.
v There is adequate space around the server to allow the server cooling system to
work properly. Leave approximately 50 mm (2.0 in.) of open space around the
front and rear of the server. Do not place objects in front of the fans. For proper
cooling and airflow, replace the left-side cover before turning on the server.
Operating the server for extended periods of time (more than 30 minutes) with
the left-side cover removed might damage server components.
v Yo u have followed the cabling instructions that come with optional adapters.
v Yo u have replaced a failed fan within 48 hours.
v Yo u have replaced a hot-swap drive within 2 minutes of removal.
v Yo u do not remove the air baffle while the server is running. Operating the server
without the air baffle might cause the microprocessor to overheat.
v Microprocessor socket 2 always contains either a microprocessor baffle or a
microprocessor and heat sink.
© Copyright IBM Corp. 2004, 2007 11
Working inside the server with the power on
The server supports hot-swap devices and is designed to operate safely while it is
turned on and the cover is removed. Follow these guidelines when you work inside
a server that is turned on:
v Avoid wearing loose-fitting clothing on your forearms. Button long-sleeved shirts
before working inside the server; do not wear cuff links while you are working
inside the server.
v Do not allow your necktie or scarf to hang inside the server.
v Remove jewelry, such as bracelets, necklaces, rings, and loose-fitting wrist
watches.
v Remove items from your shirt pocket, such as pens and pencils, that could fall
into the server as you lean over it.
v Avoid dropping any metallic objects, such as paper clips, hairpins, and screws,
into the server.
Handling static-sensitive devices
Attention: Static electricity can damage electronic devices, including the server.
To avoid damage, keep static-sensitive devices in their static-protective packages
until you are ready to install them.
To reduce the possibility of damage from electrostatic discharge, observe the
following precautions:
v Limit your movement. Movement can cause static electricity to build up around
you.
v Handle the device carefully, holding it by its edges or its frame.
v Do not touch solder joints, pins, or exposed circuitry.
v Do not leave the device where others can handle and damage it.
v While the device is still in its static-protective package, touch it to an unpainted
metal part of the server for at least 2 seconds. This drains static electricity from
the package and from your body.
v Remove the device from its package and install it directly into the server without
setting down the device. If it is necessary to set down the device, put it back into
its static-protective package. Do not place the device on the server cover or on a
metal surface.
v Take additional care when handling devices during cold weather. Heating reduces
indoor humidity and increases static electricity.

Updating the server configuration
When you start the server for the first time after you add or remove an internal
option or external SCSI device, you might receive a message that the configuration
has changed. The Configuration/Setup Utility program starts automatically so that
you can save the new configuration settings. For more information, see the section
about configuring the server in the User’s Guide on the IBM xSeries Documentation
CD.
Some options have device drivers that you must install. See the documentation that
comes with each option for information about installing device drivers.
The server comes with at least one microprocessor. If more than one
microprocessor is installed, the server can operate as a symmetric multiprocessing
(SMP) server. You might have to upgrade the operating system to support SMP. For
more information, see the section about using the ServerGuide™ Setup and
Installation CD in the User’s Guide and the operating-system documentation.
If the server has an optional RAID adapter and you have installed or removed a
hard disk drive, see the documentation that comes with the RAID adapter for
information about reconfiguring the disk arrays.
If you have installed a Remote Supervisor Adapter II SlimLine to manage the server
remotely, see the Remote Supervisor Adapter II SlimLine and Remote Supervisor
Adapter II User’s Guide, which comes with the adapter, for information about setting
up, configuring, and using the adapter.
For information about configuring the integrated Gigabit Ethernet controller, see the
User’s Guide.

Universal Serial Bus connectors
The server has one Universal Serial Bus (USB) version 2.0 connector on the front
of the server and two USB version 2.0 connectors on the rear of the server.
USB is a serial interface standard for telephony and multimedia devices. It uses
Plug and Play technology to determine the type of device that is attached to the
connector.
Notes:
1. If you attach a standard (non-USB) keyboard to the keyboard connector, the
USB ports and devices will be disabled during the power-on self-test (POST).
2. If you install a USB keyboard that has a mouse port, the USB keyboard
emulates a mouse, and you will not be able to disable the mouse settings in the
Configuration/Setup Utility program.
3. Check to make sure that your NOS supports USB devices.
4. For additional information about USB version 1.1 or 2.0 devices, go to
http://www.usb.org/.

Chapter 5. Diagnostics
This section provides basic troubleshooting information to help solve some common
problems that might occur with the server.
If you cannot locate and correct the problem using the information in this section,
see Appendix A, “Getting help and technical assistance,” on page 151 for more
information.
General checkout
Follow the checkout procedure for diagnosing hardware problems. Review the
following information before performing the checkout procedure:
v Read Appendix B, “Safety information,” on page 153.
v The server diagnostic programs are stored in electrically erasable programmable
read-only memory (EEPROM) on the system board that is shared with the BIOS
code. These programs provide the primary methods of testing the major
components of the server. If you are not sure whether a problem is caused by
the hardware or by the software, you can run the diagnostic programs (see
“Diagnostic programs, error codes and messages” on page 91) to confirm that
the hardware is working correctly.
v When you run the diagnostic programs, a single problem might cause several
error messages. If you receive several error messages, correct the cause of the
first error message. The other error messages might not occur the next time you
run the diagnostic programs.
v Before running the diagnostic programs, you must determine whether the failing
server is part of a shared hard disk drive cluster (two or more servers sharing
external storage devices). If you suspect that it is part of a cluster, you can run
all diagnostic programs except the ones that test the storage unit (that is, a hard
disk drive in the storage unit) or the storage adapter that is attached to the
storage unit. The failing server might be part of a cluster if any of the following
conditions is true:
– The customer identifies the failing server as part of a cluster.
– One or more external storage units are attached to the failing server and at
least one of the attached storage units is also attached to another server or
unidentifiable device.
– One or more servers are located near the failing server.
Important:
v
1. For servers that are part of a shared hard disk drive cluster, run one test at a
time. Do not run any suite of tests, such as “quick” or “normal” tests, because
this could enable the hard disk drive diagnostic tests.
2. If more than one error code is displayed, correct the first error. The other
error codes might not occur the next time you run the diagnostic programs.
3. If the server is suspended and no beep or more than one beep sounds, see
“Beep symptoms” on page 104 or “No-beep symptoms” on page 108.
4. If the server is suspended and a POST error code is displayed, see “POST
error codes” on page 108.
5. If the server is suspended and no error message is displayed, see “Error
symptoms” on page 122 and “Undetermined problems” on page 140.

Diagnostic tools overview
The following tools are available to help you identify and resolve hardware-related
problems:
v POST beep codes, error messages, and error logs
The power-on self-test (POST) generates beep codes and messages to indicate
successful test completion or the detection of a problem (see “POST error logs”
on page 90).
The POST error log contains the three most recent error codes and messages
that the system has generated during POST.
The system-error log contains all the error messages that were issued during
POST.
Note: The system-error log is available only with the Remote Supervisor Adapter
II SlimLine.
v Diagnostic programs and error messages
The server diagnostic programs, stored in upgradable read-only memory (ROM)
on the system board, are the primary method of testing the major components of
the server (see “Diagnostic programs, error codes and messages” on page 91).
v ServerGuide error symptoms
ServerGuide error symptoms are described at “ServerGuide error symptoms” on
page 131.
v SCSI error messages
For information on SCSI errors, see “Small computer system interface messages”
on page 97 and “SCSI error codes” on page 132
v Light path diagnostics
The server has light-emitting diodes (LEDs) to help you identify problems with
server components. By following the light path, you can identify the type of
problem that occurred. The light path begins with the LEDs on the operator
information panel (see “Light path diagnostics” on page 93).
v Error symptom tables
These tables list problem symptoms, along with suggested steps to correct the
problems (see the “Error symptoms” on page 122).
Chapter 5. Diagnostics 89
POST error logs
When you turn on the server, it performs a series of tests to check the operation of
server components and some of the options installed in the server. This series of
tests is called the power-on self-test, or POST.
If POST finishes without detecting any problems, a single beep sounds, and the first
screen of the operating system or application program appears.
If POST detects a problem, more than one beep sounds, an error message appears
on the screen, or both (see “Beep symptoms” on page 104 and “POST error codes”
on page 108).
Note: A single problem might cause several error messages. When this occurs,
work to correct the cause of the first error message. After you correct the
cause of the first error message, the other error messages usually will not
occur the next time you run the test.
The POST error log contains the three most recent error codes and messages that
the system generated during POST.
The system-error log or the BMC log contains all messages that were issued during
POST and all system status messages from the service processor.
Note: The system-error log is available only with the Remote Supervisor Adapter II
SlimLine.
Viewing error logs from the Configuration/Setup Utility program
To view the POST error log, the system-error log, or the BMC log from the
