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 port s, 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 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 ca use several e rror 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 m ight 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
addit ionally attached to another syste m or unidentifiable source.
• One 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 test s wh ic h t e st th e s to rag e u ni t ( DASD res id in g i n th e
storage unit) or the storage adapter attached to the storage
unit.
Notes:
1. For syst em s tha t are pa r t of a s hare d DASD c lu ster, run
one test at a time in looped mode. Do not run all t ests
in looped mode, as this could enable the DASD diagnostic tests.
2. If multiple error codes are displayed, diag nose the first
error code displayed .
3. If the computer hangs with a POST error, go to the
“Symptom-to-FRU index” on page 129.
4. If the computer hangs and no error is displayed, go to
“Undet ermined problems” on page 147.
5. Power supply problems, see “Symptom-to-FRU index”
on page 129.
6. Safety i nformation, see “Safety information” on page
155.

7. For intermittent problems, check the error log; see
“POST error messages” on page 10.
1. IS THE SYSTEM PART OF A CLUSTER?
YES. Schedule maintenance with the customer. Shut down
all syst ems related to the cluster. Run storage test.
NO. Go to step 2.
2. IF THE SYSTEM IS NOT PART OF A CLUSTER:
• Power-off the computer and all external devices.
• Check all cables and power cords.
• Set all display controls to the middle position.
• Power-on all external 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 141.
• Check the System Error Log. If an error was
recorded by the system, see “Symptom-to-FRU
index” on page 129.
• Start the Diagnostic Programs. See “Diagnostic
programs and error messages” on page 10.
• Check for the followi ng 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 “Symptom-to-FRU index”
on page 129.
YES. Run the Diagnostic Programs. If necessary, refer to
“Diagnostic progr ams and error messages” on page 10.
If you receive an error, go to “Symptom-to-FRU index” on
page 129.
If the diagnostics completed successfully and you still sus-
pect a problem, see “Undetermined problems” on page 147.

Server features
The uni que design of the server takes advantage of
advancem ents in symmetric multiprocessing (SM P), data
storage, and memory management. The server combines:
• Impressive performance using an innovative approach
The server supports up to two Pentium III microprocessors. The server com es with at least one proce s sor
installed; you can install an additional processor to
enhance performance and provide SMP capability.
• Large system memory
The memory bus in the server supports up to
2gigabytes (GB) of system memory. The memory controller provides error correcting code (ECC) support for
up to four industry standard PC133, 3.3 V, 168-pin, 8byte, registe red, syn chro nous- dynam ic-ra ndom ac cess
memory (SDRAM) dual inline memory modules
(DIMMs).
• System-management capabilities
The Netfinity Manager software provided on the Serv-
erGuid e CDs enables you to manage the functions of
the ser ver locally and remotely. See “Netfinity Manager” on page 75 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 c onnecting to 10-Mbps or 100-Mbps networks. T h e
server automatically selects between 10BASE-T and
100BASE-TX environments. The controller provides
full-duplex (FDX) capability, which enables simultaneous transmission and reception of data on the Ethernet loca l ar e a ne tw or k ( LAN ).
• IBM ServerGuide CDs
The ServerGuide CDs included with IBM Netfinity serv-
ers provide programs to help you set up the server and
instal l the network operating system (NOS). The ServerGuid e program detects the hardware optio ns that are
installed, and provides the correct configuration program and device drivers. In addition, the ServerGuide
CDs include a variet y of applicat ion programs for the
server.
Reliability, availability, and serviceability
Three of the most imp ortant features in server design are
reliability, availability, and serviceability (RAS). These factors help to ensure the integrity of the data stored on the
server; that the server is available when you want to use it;
and that should a failure occur, you can easily diagno se and
repair the failure with minimal inconvenience.
The following is an abbreviated list of the RAS features that
the server supports.
• Menu-driven setu p, sy s tem co nfi gu r at io n, R AID co nf iguratio n, and diagnosti c pro gr a m s
• Power-on self-test (POST)
• Er ror co de s and message s
• Upgradable BIOS and diagnostics
• Automatic restart after a power failure

This section provides basic troubleshooting information to
help you resolve some c ommon problems that might occur
with the server.
If you ca nnot locate and correct the problem using the information in this section, refer to “Symptom-to-FRU index” on
page 129 for more information.
Diagnostic tools overview
The following tools are available to help you identify and
resolve hardware-related problems:
• POST beep codes, error messages , and error logs
The power-on self-test (POST) generates beep codes
and mess ag es to i nd ic at e suc ces sf ul t est com pl eti on or
the detection of a problem. See “POST” for more information.
• Diagnostic programs and error messages
The server diagnostic programs are stored in upgrad-
able read-only memory (ROM) on th e system board.
These pr ograms are the primary method of testing the
major components of the server. See “Diagnostic programs and error messages” on page 10 for more information.
POST
When you turn on the se rver, it performs a series of tests to
check th e 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 and
an error mess ag e ap pe ars on th e sc ree n. Se e “P OS T bee p
codes” and “POST error messages” on page 10 for more
information.
Notes:
1. If you have a power-on 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 cor rect the cause of
the first error message. After you correct the cause of
the fi rst error message, the other error messages usually will not occur the next time you run the test .
POST beep codes
POST gene rates beep code s to indicate successful compl etion or the detection of a problem.

• One beep indicates the successful completion of
POST .
• More than one beep in dicates that POST detected a
problem. For more information, see “Beep symptoms”
on page 129.
POST error messages
POST error messages occur during startup when POST
finds a pro bl em wi t h t he ha rd war e or de t ec ts a ch an ge in th e
hardware configur ation. For a list of POST er rors, see
“POST error codes” on page 141.
Error logs
The POST error log contains the three most recent error
codes and messages that the system generated during
POST.
To view th e contents of the error log, start the Configuration/Setup Utility program (see “Starting the Configuration/Setup Utility program” on page 33); then, select Error
Logs from the main menu.

Diagnostic error message tables
For des criptions of the error m essages that might appear
when you run the diagnostic programs, see “Diagnostic error
codes” on page 133. If diagnostic error messages appear
that are not listed in those tables, make sure that the server
has the latest level s of BIOS, Adva nced System Management Processor, ServeRAID, and diagnostics microc ode
installed.
Power checkout
Power problems can be difficult to troubleshoot. For
instance, a short circuit can exist anywhere on any of the
power distribution busses. Usu ally a short circuit will cause
the power subsystem to shut down because of an overcurrent condition.
A general procedure for trou bleshootin g po w er problems is
as follows:
1. Power off the system and disconnect the AC cord(s).
2. Check for loose cables in the power subsystem. Also
check for short circuits, for instance if there is a loose
screw causing a short circuit on a circuit board.
3. Remove adapters and disconnect the cables and
power connectors to all internal and external devices
until sy s tem is at minimum configu r ati on requ ir e d for
power on (see "Minimum operating requirements" on
page 148).
4. Reconnect the AC cord and power on the system. If
the system powers up successfully, replace adapters
and devices one at a time until the problem is isolated.
If system does not power up from minimal configuration, replace FRU s of minimal configuration one at a
time unt il the problem is isolated.
T o use this method it is important to know the minimum configuration required for a system to power up (see page 148).
Recovering BIOS
If the BIOS code in the server has become corrupted, such
as from a power failure during a flash update, you can
recover the BIOS using the Fla s h ROM Page-Swap Jumper
(J38) and a BIOS flash diskette .
Note: You can obtain a BIOS flash diskette from one of the
follo wing sources:
• Use the ServerGuide program to make a BIOS
flash diskette.
• Download a BIOS flash diskette from the World
Wide Web. Go to http://www.pc.ibm.com/support/, select IBM Server Support, and make the
selections for the server.
Diagnostics 13
The flash memory of the server consists of a primary page
and a backup page. The J38 jumper controls which page is
used to start the server. If the BIOS in the primary page is
corrupted, you can use the backup page to start the server;
then bo ot th e B I OS Fl ash D isk ett e t o res to r e th e BI OS to the
prima r y pa ge .
To recover the BIOS:
1. Turn off the serv er and peripheral devices and discon nect all external cables and power cords; then, remove
the cover.
2. Locate jumper J38 on the processor board (see “Sys-
tem board switches and jumpers” on page 42). The
jumper consists of three pins, two of which are cove red
by a jumper.
3. Move the J38 jumper from its current location to connect the center pin and the pin on the opposite end of
the co nnector block, as shown in the following diagram:
4. Insert the BIOS flash diskette into the diskette drive.
5. Restart the server.
6. The system begins the power-on self-test (POST).
Select 1 – Update POST/BIOS from the menu that contains various flash (update) options.
7. When you are asked whether you want to save the current code to a diskette, type N.
8. You will be asked to choose which language you wish
to use. Select your language (0-7) and press Enter to
acce pt yo ur choice.
9. Do not reboot the system at this time.
10. Remove the BIOS Flash Diskette from the diskette
drive.
11. Power-off the server.
12. Move jumper J38 back to its original setting to return to
normal startup mode.
13. Restart the server. The system should start up normally.

If you cannot find the problem there, go to “Starting the diagnostic programs” on page 11 to test the server.
If you have j ust ad ded ne w softw ar e or a ne w optio n an d the
server is not working, do the follow ing before using the error
symptoms table:
• Remove the software or device that you just added.
• Run the diagnostic tests to determine if the server is
runnin g correctly.
• Reins tall the new software or new device.
Troubleshooting the Ethernet controller
This section provides troubleshooting information for problems tha t might occur with the 10/100 Mbps Ethernet controller.
Network connection problems
If the Ethernet controller cannot connect to the net work,
check th e following:
• Make sur e that the cable is instal led 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 controller to operate at 100
Mbps, you must use Category 5 cabling.
If you dir ec tl y con nect t wo w orks ta t ions ( wit ho ut a hu b) ,
or if you are not usin g a hub with X por ts, use a crossover cable.
Note: To determine whether a hub has an X port,
check th e port label. If the label contains an
the hub ha s an X por t.
• Determine if the hub supports auto-negotiation. If not,
try configuring the integrated Ethernet controller manually to match the speed and duplex mode of the hub.
• Check the Ethernet controller lights on the operator
information panel.
These lights indicate whether a problem exists with the
connector, cable, or hub.
— The Ethernet Link Status light illuminates when
the Ethe r net co nt ro ll er rec ei ve s a L INK pu ls e fr om
the hub. If the light is off, there might be a defective co nnector or cable, or a problem with the hub.
— The Ethernet Transmit/Receive Activity light illumi-
nates when the Ethernet controller sends or
receives data over the Ethernet Network. If the
Ethernet Transmit/Receive Activity light is off,

,
make sure that the hub and network are operating
and that the correct device drivers are loaded.
— The Ethernet Speed 100 Mbps light illuminates
when the Ethernet controller LAN speed is
100 Mbps.
• Make sure that you are using the correct device drivers,
suppli ed with the ser v er.
• Check for operating sys tem-specific causes for the
problem.
• Make sur e that the device drivers on the client and
server ar e using the same protocol.
• Test the Ethernet controller.
How you test the Ethernet controller depends on which
operating system you are using (see the Ethernet controller device driver README file).

Suggested Action
The PCI BIOS interrupt settings are
incorrect.
Check the following:
• Determin e if the inte r ru pt (IR Q )
setting assigned to the Ethernet
controller is also assigned to another
device in the Configuration/Setup
Utility program.
Although interrupt sharing is allowed
for PCI devices, some devices do not
function well when they share an
interrupt with a dissimilar PCI device.
Try ch an ging t he I RQ assi gn ed to t he
Ethernet controller or the ot her
device. For exam ple, for NetWare
Versions 3 and 4 it is recommended
that disk controllers not share
interrupts with LAN controllers.
• Make sure that you are using the
most recent device driver available
from the World Wide Web.
• Run the network diagnostic program.

Suggested Action
Check the following:
• Make sure that the hub is turned on.
• Check all connections at the Ethernet
controller and the hub.
• Check the cable. A crossover cable
is required unless the hub has an
designation.
• Use another po rt on the hub.
• If the hub does not support autonegotiation, manually configure the
Ethernet controller to match the hub.
• If you manually configured the duplex
mode, make sure that you also
manually configure the speed.
• Run diagnostics on the LEDs.
Check the following:
Note: The Ethernet Transmit/Receive
Activity LED illuminates only when
data is sent to or by this Ethernet
controller.
• Make sure that you have loaded the
network device drivers.
• The network might be idle. Try
sendin g da ta from this workstat ion.
• Run diagnostics on the LEDs.
• The function of this LED can be
changed by device driver load
parameters. If necessary , remove
any LED parameter settings when
you load the device drivers.
Check the following:
• Make sure that you are using
Categor y 5 cab lin g w he n op erating
the server at 100 Mbps.
• Make sure that the cables do not run
close to noise-inducing sources like
fluo rescent lights.
