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, and hard
drives. You can also use them to test some external devices. See “Diagnostic
programs and error messages” on page 13.
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 “POST error codes” on page 93.
4. If the computer hangs and no error is displayed, go to “Undetermined problems”
on page 102.
5. Power supply problems, see “Power supply LED errors” on page 92.
6. Safety information, see “Safety information” on page 109.
7. For intermittent problems, check the error log; see “Error logs” on page 12.

4Hardware Maintenance Manual: xSeries 342 Type 8669

Server features
The xSeries 342 is designed to be cost-effective, powerful, and flexible. The server
offers:
vImpressive performance using an innovative approach to SMP
The server supports up to two Intel Pentium III microprocessors. The server
comes with one microprocessor installed; you can install an additional
microprocessor to enhance performance and provide SMP capability.
vLarge data-storage and hot-swap capabilities
All models of the server support up to three hot-swap hard disk drives. This
hot-swap feature enables you to remove and replace hard disk drives without
turning off the server. The xSeries 3-Pack Ultra 160 Hot-Swap Expansion Kit
option is available to add three additional drives.
vOptional PCI adapters
The server uses peripheral component interconnect (PCI) bus architecture to
provide compatibility with a wide range of existing hardware devices and software
applications. The server supports up to five PCI adapters in the expansion slots
on the system board.
vRedundant cooling capability
The redundant cooling capability of the hot-swap fans in the server allow
continued operation if one of the fans fails. You can also replace a failing
hot-swap fan without turning off the server.
vOptional redundant power capability
You can install an additional 270-watt power supply in the server to provide
redundant power for the server. The Power Non-Redundant (NON) light emitting
diode (LED) in the group of diagnostic LEDs on the system board is lit when the
power load is 270 watts or greater with two power supplies installed.
vLarge system memory
The memory bus in the server supports up to 4 GB (GB equals approximately
1000000000 bytes) of system memory. 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).
vIBM integrated system management processor (ISMP)
The integrated system management processor provides environmental monitoring
for the server. When environmental conditions exceed thresholds or when system
components fail, the ISMP lights the Light Path Diagnostics
™
LEDs to indicate
the location of the problem. Critical errors, as well as environmental and
configuration information, are also included in the error log.
If an optional Remote Supervisor Adapter is installed on the Advanced System
Management (ASM) interconnect network, you can view the system health;
update the ISMP code; power on, power off, and restart the server; view the error
log; view the vital product data; and send alerts over the ASM interconnect
network.
vIntegrated 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 networks. The
server automatically selects between 10BASE-T and 100BASE-TX. The controller
provides full-duplex (FDX) capability, which allows simultaneous transmission and
reception of data on the Ethernet local area network (LAN).
vRedundant network-interface card
General information 5

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.
vOptional digital linear tape drive
The addition of an optional digital linear tape drive (DLT) allows quick backup of
large amounts of data.
vIBM ServerGuide
™
CDs
The ServerGuide CDs included with the server provide programs to help you set
up the server and install the network operating system (NOS). The ServerGuide
program detects the hardware options installed, and provides the correct
configuration programs and device drivers. In addition, the ServerGuide CDs
include a variety of application programs for the server.
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
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.
The following is an abbreviated list of the RAS features that the server supports.
vMenu-driven setup, system configuration, RAID configuration, and diagnostic
programs
vPower-on self-test (POST)
