General checkout
The server diagnostic programs are stored in upgradable read-only memory (ROM)
on the system bsoard. 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 12.
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 the “Symptom-to-FRU index”
on page 119.
4. If the computer hangs and no error is displayed, go to “Undetermined
problems” on page 142.
5. Power supply problems, see “Symptom-to-FRU index” on page 119.
6. Safety information, see “Safety information” on page 152.
7. For intermittent problems, check the error log; see “POST error messages” on
page 12.
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.
© Copyright IBM Corp. 1999 1

2. THE SYSTEM IS NOT PART OF A CLUSTER.
vPower-off the computer and all external devices.
vCheck all cables and power cords.
vSet all display controls to the middle position.
vPower-on all external devices.
vPower-on the computer.
vRecord 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 131.
vCheck the information LED panel System Error LED; if on, see “Diagnostic
panel LEDs” on page 122.
vCheck the System Error Log. If an error was recorded by the system, see
“Symptom-to-FRU index” on page 119.
vStart the Diagnostic Programs. See “Diagnostic programs and error
messages” on page 12.
vCheck for the 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 “Symptom-to-FRU index” on page 119.
YES. Run the Diagnostic Programs. If necessary, refer to “Diagnostic programs and
error messages” on page 12.
If you receive an error, go to “Symptom-to-FRU index” on page 119.
If the diagnostics completed successfully and you still suspect a problem, see
“Undetermined problems” on page 142.

Server features
The unique design of the server takes advantage of advancements in symmetric
multiprocessing (SMP), data storage, and memory management. The server
combines:
vImpressive performance using an innovative approach to SMP
The server supports up to four Pentium III Xeon microprocessors. The server
comes with one microprocessor installed; you can install additional
microprocessors to enhance performance and provide SMP capability.
vLarge data-storage and hot-swap capabilities
All models of the server support up to 10 slim-high or 7 half-high hot-swap
hard disk drives. This hot-swap feature enables you to remove and replace hard
disk drives without turning off the server.
vLarge system memory
The memory bus in the server supports up to 16 GB of system memory. The
memory controller provides error correcting code (ECC) support for up to 16
industry-standard, 3.3 V, 168-pin, 8-byte, registered, dual inline memory modules
(DIMMs).
vSystem-management capabilities
The server comes with a Netfinity Advanced System Management Processor on
the system board. This processor, in conjunction with the Netfinity Manager
software provided on the ServerGuide CDs, enables you to manage the functions
of the server locally and remotely. The Netfinity Advanced System Management
Processor also provides system monitoring, event recording, and dial-out alert
capability.
Note: The Netfinity Advanced System Management Processor is sometimes
referred to as the service processor.
vIntegrated network environment support
The server comes with an Ethernet controller. This Ethernet controller on the
system board has an interface for connecting to 10-Mbps or 100-Mbps networks.
The server automatically selects between 10BASE-T and 100BASE-TX. The
controller provides full-duplex (FDX) capability, which enables simultaneous
transmission and reception of data on the Ethernet local area network (LAN).
vRedundant network-interface card
The addition of an optional, redundant network interface card (NIC) provides a
failover capability to a redundant Ethernet connection. If a problem occurs with
the primary Ethernet connection, all Ethernet traffic associated with this primary
connection is automatically switched to the redundant NIC. This switching
occurs without data loss and without user intervention.
vIBM ServerGuide CDs
The ServerGuide CDs included with the Netfinity server provide programs to
help you set up the server and install the network operating system (NOS). The
ServerGuide program detects the hardware options that are installed, and
provides the correct configuration programs and device drivers. In addition, the
ServerGuide CDs include a variety of application programs for the server.
General information 5

Reliability, availability, and serviceability
Three of the most important 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 diagnose and repair the failure with minimal
inconvenience.
