The server diagnostic prog rams 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 programs and error messages” on page 10.
Also, if you cannot determine whether a problem is caused by the hardware or by the
softw a re, you ca n run the diagnostic programs t o confirm that the hard wa re 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 par t of a shared DASD cluster (two or mor e 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:
•The customer identifies the system as part of a cluster.
•One 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.
•One or more sy stems are loca te d 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 clus ter, 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, diagno se the firs t error code dis pla yed.
3. If the computer hangs with a POST error, go to the “Chapter . Symptom-to - FRU
index,” on page 85.
4. If the computer hangs and no error is displayed, go to “Undetermined problems”
on page 100.
5. Po wer supply problems, see “Chapter . Symptom-to-FRU index,” on page 85.
6. Safety information, see “Safety information” on page 105.
7. Fo r intermittent problems, check the error log; see “POST error mess ages” on
page 9.
YES. Schedule maintenance with the customer. Shut down all systems related to the
cluster. Run storage test.
NO. Go to step 2.
2. IF THE SY STEM IS NOT PART OF A CLUSTER:
•Power-off the computer and all external devices.
•Chec k al l cables an d power cords.
•Set all display controls to the middle position.
•Power-o n all ext e rna l devices.
•Power-on the computer.
•Record any POST error messages displayed on the screen. If an error is displayed, look up the first error in the “POST error codes” on page 94.
•Check the System Error Log. If an error was recorded by the system, see
“Chapter . Symptom-to-FRU index,” on page 85.
•Start the Diagnostic Programs. See “Diagnostic p rograms and error messages” on page 10.
•Check for th e following responses:
a. One beep.
b. Readable instructions or the Main Menu.
3. DID YOU RECEIVE BOTH OF THE CORRECT RESPONSES?
NO. Find the failure symptom in “Chapter . Symptom-to-FRU index,” on page 85.
YES. Run the Diagnostic Programs. If necessary, refer to “Diagnostic programs and
error messages” on page 10.
If you receive an error, go to “Chap te r . Sy m p to m-to-F R U i nd e x ,” on page 85.
If the diagnostics completed successfully and you still suspect a problem, see
“Undetermined problems” on page 100.

See the documentation provided with the systems-management software for
more information.
•Integrated network environment support
The server comes with an Ethernet controller on the system board. This Ethernet
controller has an interface for connecting to 10-Mbps or 100-Mbps netwo rks. The
server automatically selects between 10BASE-T and 100BASE-TX environments.
The controller provides full-duplex (FDX) capability, which allows simultaneous
transmission and recep tion of data on the Ethernet local area network ( LA N).
•IBM ServerGuide™ CDs
The ServerGuide CDs included with IBM servers provide programs to help set up
the server and install the network operating system (NOS). The ServerGuide
program detects the hardware options installed, and provides the correct
configuration program and device drivers. In addition, the ServerGuide CDs
include a variety of application programs for the server.
Note: The latest level of BIOS for the server is also available through the World
Wide Web. Refer to “Recovering BIOS ” on page 14 for the appro priate
World Wide Web addresses.

Diagnostics
This section provides basic troubleshooting information to help you resolve some
common pr oblems that might occur wi th the server.
If you cannot locate and correct the problem using the information in this sec tion,
refer to “Symptom-to-F RU index” on page 85 for more information.
Diagnostic tools overview
The following tools are available to help you identify and resolve hardware-related
problems:
•POST bee p cod es
The power-on self-test (POST) generates beep codes and messages to indicate
successful test completion or the det e ction of a probl e m. See “POST” for more
information.
•Diagnostic programs and error messages
The server diagnostic programs are provided on the IBM Enhanced Diagnostics
CD. These programs test the major components of the server . See “Diagnostic
programs and error messages” on page 10 for more information.
POST
When you turn on the server, it performs a series of tests to check the operation of
server components an d some of the options installed in th e se rver. This se ries of tests
is called the power-on self-test or POST.
If POST finishes without detecting any problems, the first window of the operating
system or application program appears.
Note:
1. If you have a power-on passw ord 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 usuall y will no t
occur the next ti m e y ou ru n th e tes t .
POST beep code descriptions
POST generates beep codes to indicate successful completion or the detection of a
problem.
•One short beep indicates the successful completion of POST.
•More than one beep indicates that POST detected a problem. For more information, see “Beep symptoms” on page 85“.
POST error messages
The possible types of beep codes that your system might emit are:
Indicates th at a memory error has occurred. Ensure that all DIMM s are
correctly installed.
One long beep and two short beeps
Indicates that a video err or has occurred and the BIOS cannot initialize the
video screen to display any additional i nformation. Ensure that the video
adapter is correctly installed.
For a list of POST errors, see “POST error co de s” on page 94.
Small computer system interface messages (some models)
The following table lists actions to take if you receive a SCSI error message.
Note: If the server does not have a har d disk drive, i gnore any mess age that indicates
that the BIOS is not installed.
You will get these messages only when running the SCSI Select Utility.
SCSI MessagesDescription
AllOne or more of the following might be causing the problem.
•A failing SCSI device (adapter or drive)
•An improper SCSI configuration
•Duplicate SCSI IDs in the sam e SCSI chain
•A n improperly installed SCSI terminator
•A defectiv e SCSI terminator
•A n improperly installed cable
•A defectiv e cable
Action:
Verify th a t :
•The external SCSI devices are turned on. External SCSI devices must
be turned on before the server.
•The cables for all external SCSI devices are connected correctly.
•The last d e vice in each SCSI ch ai n i s terminated p r operly.
•The SCSI devices are configured correctly.
If the above items are correct, run the diagnostic programs to obtain
additional information about the failing device.
Table 2. SCSI messages.
Diagnostic programs and error messages
The server diagnost ic p rograms are stored on the IBM Enhanced Diagnostics CD. These
programs provide the primary methods of tes ting the major components of the server.
Diagnostic error messages indicate that a problem exists; they ar e not inten ded to be
used to identify a failing part. Troubleshooting and servicing of complex problems
that are indicated by error messages should be performed by trained service
personnel.

installed.
Te st Spec i fi c Stri ng
This is additional informa tion th at is used to analyz e the problem.
Diagnostics 11
Starting the diagnostic programs
The IBM Enhanced Diagnostics programs will isolate your server hardware from
software that you have installed on your hard disk drive. The programs run
independently of the operating system, and must be run either from the CD or diskette.
This method of testing is generally used when other methods are not accessible or
have not been successful in isolating a problem suspected to be hardware related.
An IBM Enhanced Diagnostics CD comes with the server. You can also download the
latest image of the diagnostics from the World Wide Web at
http://www.ibm.com/pc/support.
Using the diagnostics CD

load. Follow the instructions on the screen to run the diagnosti cs.
When the tests have completed, you can view the Test Log by selectin g Utility from
the top of the screen.
If the hardware checks out OK but the problem persists during normal server
operations, a software error might be the cause. If you suspect a software problem,
refer to the information that comes with the software package.
Viewing the test log
The test log records data about syste m f a ilures and othe r pertinent i nformation. Th e
test log will not contain any information until after the diagnostic program has run.
Note: If you already are running the diagnostic programs, begin with step 4.
1. Insert the IBM Enhanced Diagnostics CD.
2. Turn on the system and watch the screen.
If the syst e m is on, shut down your operating system and restart the system.

Note: The syst e m mai ntains the test -log data while th e system is power e d on.
When you turn off the power to the server, the test log is cleared.
Diagnostic error message tables
For descriptions of the error messages that might appear when you run the diagnostic
programs, see “Diagnost ic error codes” on page 89. If diagnostic error messages
appear that are not listed in those tables, make sure that the server has the latest levels
of BIOS, Advance d System Managemen t P rocessor, ServeRAID, and diagnostics
microcode installed.
Power checkout
Power problems can b e difficu lt to trou bleshoot. For instance, a short circui t can exist
anywhere on any of the power distributio n busses. Usually a short circuit will cause
the power su b s ystem to shut d own because of an overcurrent conditi o n.
A general procedure for troubleshooting power problems is as follows:
Diagnostics 13
1. Power off the server and disconnect the AC cord(s).
2.Check for loose cables in the power subsystem. Also check for short circuits, for
3. Remove adapters and disconnect the cables and power connector s to al l internal
4. R econnect the AC cord and power on the server. If the server powers up
To use this method it is important to know the minimum configuration required for a
server to power up (see page 100).
Recovering BIOS
If the BI O S has bec ome c orr up t ed, su ch as fr om a pow er f ai lu r e du ri n g a fl ash up dat e,
you can recover the BIOS using the boot block jumper and a BIOS flash diskette. The
boot block jumper selects which of two BIOS images to use. In the normal position,
the jumper will be installed on pins 2 and 3. In the alternate block position, the jumper
will be installed on pins 1 and 2.
Note: You can obtain a BIOS flash diskette fr om one of the following sources:
instance if there is a loose screw causing a short circuit on a circuit board.
and external devices until server is at minimum configuration required for power
on (see "Minimum operating requirements" on page 100).

Clearing CMOS
If you need to erase configuration information, you must move the CMOS jumper. See
the illustration in “Recovering BIOS” on page 14 for the location of the CMOS jumper.
The default position is a jumper installed on pins 1 and 2. Before you change the
position of this jumper , you must turn off the server and peripheral devices, and
disconnect all external cables and power cords . Remove the cover and then move the
jumper to pins 2 and 3.
After moving the jumper, wait at least 5 minutes for the CMOS information to clear.
Changing the position of this jumper erases all configuration and setup information,
including the power-on and administrator passwords. Therefore, you must
reconfigure the server after clearing CMOS memory (see “Ch apter . Configuring th e
server,” on page 29). If possible, record your server configuration information before
moving the CMOS jumper.
After you clear the CMOS information, move the jumper back to its normal position
(pins 1 and 2). Reconnect the external cables and power cords; then, turn on the
peripheral devices and the server.

Temperat ur e checkou t
Proper cooling of the server is important for proper operation and server reliability.
For a typical xSeries ser ve r, you should make sure:
•Each of the drive bays has either a drive or a filler panel installed
•Each of the power supply bays has either a power supply or a filler panel installed
•The server cover is in place during normal operation
•There is at l east 50 mm (2 inches) of ventilated space at the sides of t he se rv er and
100 mm (4 inches) at the rear of the server
•The server cover is removed for no longer than 30 minutes while the server is
operating
•The processor housing cover covering the proc essor and memory area is r emoved
for no longer that ten minutes while the server is operating
•A removed hot-swap drive is replaced within two minutes of removal
•Cables for optional adapters are routed according to the instructions provided
with the adapters (ensure that cables are not restricting air flow)
•The fans are operati ng correctly and the air flow is good
•A failed fan is replaced within 48 hours
In addition, ensure that the environmental specifi cat i on s for the server are met. See
“Features and specifications” on page 3“Features and specifications” on page 3.
Note: The speed of the fans will increase if:
•One fan fails.
•Ambient temperature gets too high.

Troubleshooting the Ethernet controller
This section provides troubleshooting information for problems that might occur with
the 10/100 Mbps Ethernet controller.
Network connection problems
If the Ethernet controller ca nnot connec t to the network, check the following:
•Make sure that the cable is installed correctly.
The network cable must be securely attached at all connections. If the cable is
attached but the problem persists, try a different cable.
If you set the Ethernet contr oll er to operate at 100 Mbps, you must use Cate gory 5
cabling.
If you directly connect two workstations (without a hub), or if you are not using a
hub with X ports, use a crossover cable.
Note: To determine whether a hub has an X port, check the port label. If the label
contains an X, the hub has an X port.
•Determine if the hub suppo rts auto-negotiation. If not, try configuring the
integrated Ethernet controller manually to match the speed and duplex mode of
the hub.
•Check the LAN activity light (if available) on the front of the server. The LAN
activity light illuminates when the Ethernet controller sends or receives data over
the Ethernet network. If the LAN activity light is off, make sure that the hub and
network are operating and that the correct device drivers are loaded.
•Make sure that you are using the correct device drivers, supplied with your
server.
•Check for operating server-specific causes for the problem.
•Make sure that the device drivers on the client and server are using the same
protocol.
•Test the Ethernet controller.
The way you test the Ethernet controller depends on which operating system you
are using (see the Ethernet controller device driver README file).
