2Hardware Maintenance Manual: xSeries 330 Type 8675

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 a server. Major components that can be tested include the system
board, Ethernet controller, video controller, RAM, keyboard, mouse (pointing
device), diskette drive, serial ports, hard drives, and parallel ports. Not all servers
include all these items; your hardware may differ. You can also use them to test
some external devices. See “Diagnostic programs and error messages”on page 18.
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. Safety information, see “Safety information”on page 135.
2. 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.
3. If multiple error codes are displayed, diagnose the first error code displayed.
4. If the computer hangs with a POST error, go to “POST error codes”on
page 121.
5. For intermittent problems, check the error log; see “Error logs”on page 16.
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. IF THE SYSTEM IS NOT PART OF A CLUSTER:
vPower-off the computer and all external devices.
vCheck all cables and power cords.
© Copyright IBM Corp. 2001 3

vSet all display controls to the middle position.
vPower-on all external devices.
vPower-on the computer.
vIf the computer hangs and no error is displayed, go to “Undetermined
problems”on page 128.
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 121.
vCheck the information LED panel System Error LED; if on, see “Information
panel system error LED”on page 115.
vCheck the System Error Log. If an error was recorded by the system, see
“Symptom-to-FRU index”on page 113.
vStart the Diagnostic Programs. See “Diagnostic programs and error
messages”on page 18.
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 113.
YES. Run the Diagnostic Programs. If necessary, refer to “Starting the diagnostic
programs”on page 20.
If you receive an error, go to “Symptom-to-FRU index”on page 113.
If the diagnostics completed successfully and you still suspect a problem, see
“Undetermined problems”on page 128.
4Hardware Maintenance Manual: xSeries 330 Type 8675

General information
The IBM
®
xSeries 330 Type 8675 is a one U-high
1
rack model server for
high-volume network transaction processing. This high-performance, symmetric
multiprocessing (SMP) server is ideally suited for networking environments that
require superior microprocessor performance, flexibility, reliable data storage, and
efficient memory management.
The xSeries 330 contains several IBM X-Architecture
™
technologies, which help
increase server performance and reliability. The X-Architecture technologies
provided in your server model include two of the most recent advancements in
memory management technologies.
vIBM Memory eXpansion Technology (MXT) on the xSeries 330 Type 8675
effectively expands the memory capacity of the server when an MXT-aware
operating system is running on the server.
Note: An MXT device driver supporting your operating system might be
required before MXT can be used.
vIBM Chipkill
™
Memory technology protects the system from a single chip failure
on a dual inline memory module (DIMM).
If you have access to the World Wide Web, you can obtain up-to-date information
about the server and other IBM server products at
http://www.ibm.com/eserver/xseries.

What the xSeries 330 offers
The unique design of this server takes advantage of advancements in symmetric
multiprocessing (SMP), data storage, and memory management. The server
combines:
vIBM X-Architecture
™
6Hardware Maintenance Manual: xSeries 330 Type 8675

IBM’s X-Architecture leverages proven innovative IBM technologies to build the
most powerful, scalable, reliable Intel-processor-based servers in the world.
X-Architecture includes features such as Light Path Diagnostics
™
, Predictive
Failure Analysis
®
, and the Advanced System Management processor.
vImpressive performance using an innovative approach to SMP
The server supports up to two Pentium III microprocessors. The server comes
with one microprocessor installed; you can install an additional microprocessor
to enhance performance and provide SMP capability.
vLarge system memory
The memory bus in the server supports up to 4 GB. The memory controller
provides error correcting code (ECC) support for up to four industry standard
PC133, 3.3 V, 168-pin, 8-byte, registered, synchronous-dynamic-random access
memory (SDRAM) dual inline memory modules (DIMMs). The memory
controller also provides Chipkill Memory protection. Chipkill Memory protection
is a technology that protects the system from a single chip failure on a DIMM.
The IBM Memory eXpansion Technology (MXT) chip on your server enables you
to store up to nearly twice the amount of data in system memory as was
previously possible. The MXT technology enables increased system performance
(through more available memory) without increasing system memory, or
comparable performance with half the memory. The level of increase
performance can depend on the number of applications running on the system
and the load on the system.
Notes:
1. An MXT device driver supporting the operating system might be required.
The IBM MXT device driver for Microsoft
®
Windows
®
2000 is available on
the ServerGuide
™
CD. Use the ServerGuide CDs to install the MXT device
driver, or download and install the latest device driver from
http://www.ibm.com/pc/support/ on the World Wide Web. The Red Hat
Linux
®
7.2 operating system includes MXT support natively, and does not
need a separate device driver.
2. With non-MXT-aware operating systems, the system memory is limited to the
sum of the DIMMs installed.
3. On an MXT-aware Microsoft Windows operating system, MXT support
software limits Windows Address Windowing Extensions (AWE) allocations
to approximately one-half the physical memory size (one-fourth the MXT
memory). Because Windows AWE pages are nonpageable, this restriction
prevents user applications from running out of MXT memory. This is not a
problem for most applications.
4. Device drivers must limit the locked pages count to less than the physical
memory size. Most device drivers will operate with this restriction.
vSystem-management capabilities
The server comes with an Advanced System Management (ASM) processor on
the system board. This processor, in conjunction with the system-management
software that is provided with the server, enables you to manage the functions
of the server locally and remotely. The ASM processor also provides system
monitoring, event recording, and dial-out alert capability.
Note: The ASM processor is sometimes referred to as the service processor.
The optional IBM Remote Supervisor Adapter works in conjunction with the
integrated service processor to give you a World Wide Web interface to the
system-management functions. You can manage your server over the Internet or
intranet.
General information 7

Refer to the documentation provided with the system-management software for
more information.
vIntegrated network environment support
The server comes with two Ethernet controllers on the system board. Each
Ethernet controller has an interface for connecting to 10-Mbps or 100-Mbps
networks. The server automatically selects between 10BASE-T and 100BASE-TX.
Each controller provides full-duplex (FDX) capability, which allows simultaneous
transmission and reception of data on the Ethernet local area network (LAN).
vIBM ServerGuide CDs
The ServerGuide CDs that are included with the server provide programs to
help you set up your 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 your server.
For more information about the ServerGuide CDs, see the documentation
provided with the ServerGuide software.
Reliability, availability, and serviceability features
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 your server; that your 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.
The following is an abbreviated list of the RAS features that your server supports.
vMenu-driven setup, system configuration, RAID configuration, and diagnostic
programs
vPower-on self-test (POST)

Running remote diagnostics
To run diagnostics on the server from a remote terminal, do the following:
1. Make sure the server is turned on and running.
2. Establish the connection from the remote computer to the server (see
“Connecting to the onboard service processor”on page 12) and log in.
3. When the server processor menu appears, enter 7 (boot), then enter the number
for your choice to restart the server, then enter 0(write the command to the
server).
4. Return to the main menu and immediately enter Z (Start remote video), then
enter 0 (zero). The server monitor contents are displayed on the remote
monitor.
5. When the message F2 for Diagnostics appears, press F2 on the remote
computer keyboard. The diagnostic programs screen appears. Run the
diagnostics you need. See “Diagnostic programs and error messages”on
page 18 for more information about running the diagnostics program.
Important: You cannot run the following tests remotely:
vKeyboard
vVideo
vMouse
vUSB
General information 13

vSerial ports
vASM restart (under System Management)
Also, the following tests require user interaction at the server:
vDiskette
vCDROM/DVD
vCDRW
vParallel port external loopback
vEthernet external loopback
vModem
6. When you have completed the diagnostics tests, exit the diagnostics programs.
To return to the service processor main menu, enter Ctrl-R + Ctrl-E + Ctrl-T.
Special keystrokes
When running the diagnostics programs remotely through a terminal emulation
program, some function keys might not work. Use the following key combinations
for the function keys that do not work.
To transmit: Type:
F1 Ctrl-A
F2 Ctrl-O
F3 Ctrl-L
F5 Ctrl-D
Enter Ctrl-N
Page Up Ctrl-Q
Page Down Ctrl-Z
Considerations when using IBM Remote Supervisor Adapter
To connect a remote terminal, follow the instructions in the documentation that
comes with the IBM Remote Supervisor Adapter.
When using the remote terminal to Redirect Text Console mode, keyboard control
is limited to ASCII characters and arrow keys. You can simulate some special keys
by using certain key combinations. The key combinations consist of a prefix (Ctrl-]
or Ctrl-Z) followed by designated keystrokes:
To transmit: Type:
F1-F9, F10 Prefix followed by 1-9, 0
F11 Prefix followed by -
F12 Prefix followed by =
Page Up Prefix followed by Ctrl-u
Page Down Prefix followed by Ctrl-d
Alt-F1 Prefix followed by F1
Ctrl-Alt-Del Prefix followed by Ctrl-r
Note: If one prefix does not work, use the other instead.

Diagnostics
This section provides basic troubleshooting information to help you resolve some
common problems that might occur with the server.
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”on page 16
for more information.
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 18 for more information.
vLight Path Diagnostic
The Light Path Diagnostic is used to quickly identify system errors.

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 and the
first screen of your operating system or application program appears.
If POST detects a problem, more than one beep sounds and an error message
appears on your screen. See “POST error messages”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 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.
POST error messages
The table “POST error codes”on page 121 provides information about the POST
error messages that can appear during startup.
Error logs
The POST error log contains the three most recent error codes and messages that
the system generated during POST. The System Error log contains all messages
issued during POST and all system status messages from the service processor.
You can view the contents of this error log from the Configuration/Setup Utility
program or from the diagnostics programs.
vStart the Configuration/Setup Utility program; then, select Error Logs from the
main menu. See “Starting the Configuration/Setup Utility program”on page 32
for more information.
vStart the diagnostics programs,; select Hardware Info from the top of the
diagnostics programs screen; select System Error Log from the list that appears;
then, follow the instructions on the screen. See “Starting the diagnostic
programs”on page 20 for more information.
Small computer system interface (SCSI) messages
The following table lists actions to take if you receive a SCSI error message.
Note: If the server does not have a hard disk drive, ignore any message that
indicates that the drive is not installed.
You will get these messages only when running the SCSISelect Utility. See “SCSI
error codes”on page 125.
