General checkout
The server diagnostic programs are stored in upgradable read-only memory (ROM)
on the system board. These programs are the primary method of testing the major
components of the server: the system board, Ethernet controller, video controller,
RAM, keyboard, mouse (pointing device), diskette drive, serial ports, hard drives,
and parallel port. You can also use them to test some external devices. See,
“Diagnostic tools overview”on page 11.
Also, if you cannot determine whether a problem is caused by the hardware or by
the software, you can run the diagnostic programs to confirm that the hardware is
working properly.
When you run the diagnostic programs, a single problem might cause several error
messages. When this occurs, work to correct the cause of the first error message.
After the cause of the first error message is corrected, the other error messages
might not occur the next time you run the test.
A failed system might be part of a shared DASD cluster (two or more systems
sharing the same external storage device(s). Prior to running diagnostics, verify
that the failing system is not part of a shared DASD cluster.
A system might be part of a cluster if:
vThe customer identifies the system as part of a cluster.
vOne or more external storage units are attached to the system and at least one of
the attached storage units is additionally attached to another system or
unidentifiable source.
vOne or more systems are located near the failing system.
If the failing system is suspected to be part of a shared DASD cluster, all
diagnostic tests can be run except diagnostic tests which test the storage unit
(DASD residing in the storage unit) or the storage adapter attached to the storage
unit.
Notes:
1. For systems that are part of a shared DASD cluster, run one test at a time in
looped mode. Do not run all tests in looped mode, as this could enable the
DASD diagnostic tests.
2. If multiple error codes are displayed, diagnose the first error code displayed.
3. If the computer hangs with a POST error, go to “System Error logs”on page 14.
4. If the computer hangs and no error is displayed, “Diagnostic programs and
error messages”on page 14.
5. Power supply problems, “Power supply LED errors”on page 112.
6. For intermittent problems, check the error log; “Undetermined Problems”on
page 122.
1. IS THE SYSTEM PART OF A CLUSTER?
YES. Schedule maintenance with the customer. Shut down all systems related to
the cluster. Run storage test.
NO. Go to step 2.
2. THE SYSTEM IS NOT PART OF A CLUSTER
vPower-off the computer and all external devices.

Turning off the server
Turning off the server refers to the act of disconnecting the server from the power
source.
You can turn off the server in any of the following ways:
Statement 5
CAUTION:
The power control button on the device and the power switch on the power supply do
not turn off the electrical current supplied to the device. The device also might have more
than one power cord. To remove all electrical current from the device, ensure that all
power cords are disconnected from the power source.

vYou can press the power-control button on the front of the server. This starts an
orderly shutdown of the operating system, if this feature is supported by your
operating system.
Note: After turning off the server, wait at least five seconds before you press the
power-control button to turn on the server again.
vYou might need to press and hold the power-control button for more than 4
seconds to cause an immediate shutdown of the server and to force the power
off. You can use this feature if the operating system stops functioning.
vIf the system was turned on by the Wake on LAN feature, it can be turned off
by either a software routine on by the fail-safe power-down counter.
vThe Integrated System Management Processor can turn off the server.
vYou can disconnect the server power cords from the electrical outlets to shut off
all power to the server.
Note: After disconnecting the power cords, wait approximately 15 seconds for
your system to stop running. Watch for the power-on light to stop
blinking.

Power-on light: This green LED lights when system power is present in the server.
When this light flashes, the server is in standby mode (the system power supply is
turned off and current is present). If this light is not on, the power cord is not
connected, the power supply has failed, or this LED has failed.
POST complete light: This green LED lights when the server completes the
power-on self-test (POST) without any errors.
SCSI hard disk drive in-use light: This green LED lights when there is activity on
a hard disk drive.
Information light: This amber LED lights when the information log contains
information about certain conditions in your server that might affect performance.
For example, the light will be on if your server has multiple power supplies and
does not have redundant power. An LED on the diagnostic panel on the system
board will also be on.
System error light: This amber LED lights when a system error occurs. An LED on
the diagnostic panel on the system board may also be on to further isolate the
error. See “Identifying problems using status LEDs”on page 19.
Ethernet speed light: This green LED lights when the Ethernet LAN speed is 100
Mbps during typical operation, when the system is powered off the LED remains
green.
Ethernet link status light: This green LED lights when there is an active
connection on the Ethernet port during typical operation, when the system is
powered off the LED remains green.
Ethernet transmit/receive activity light: This green LED lights when there is
transmit or receive activity to or from the server.

Diagnostics
This section provides basic troubleshooting information to help you resolve some
common problems that might occur with your server.
If you cannot locate and correct the problem using the information in this section,
refer to “Diagnostic tools overview”for more information.
Diagnostic tools overview
The following tools are available to help you identify and resolve hardware-related
problems:
vPOST 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 beep code
descriptions”on page 13 for more information.
vLight Path Diagnostics
Your server has light-emitting diodes (LEDs) to help you identify problems with
server components. These LEDs are part of the Light Path Diagnostics feature
that is built into your server. By following the path of lights, you can quickly
identify the type of system error.
vDiagnostic programs and error messages
The server diagnostic programs are stored in upgradable read-only memory
(ROM) on the system board. These programs are the primary method of testing
the major components of your server. See “Diagnostic programs and error
messages”on page 14 for more information.
vCustomized support page
You can create a customized support page that is specific to your hardware,
complete with Frequently Asked Questions, Parts Information, Technical Hints
and Tips, and Downloadable files. In addition, you can choose to receive
electronic mail (e-mail) notifications whenever new information becomes
available about your registered products.
After you register and profile your xSeries products, you can diagnose problems
using the IBM Online Assistant and you can participate in the IBM discussion
forum. For more detailed information about registering and creating a

Post
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, the first
screen of your operating system or application program appears, and the System
POST Complete (OK) light is illuminated on the operator information panel.
If POST detects a problem, more than one beep sounds and an error message
appears on your screen. See “POST beep code descriptions”on page 13 and
“System Error logs”on page 14 for more information.
Notes:
1. If you have a power-on password or administrator password set, you must
type the password and press Enter, when prompted, before POST will continue.
2. 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.
