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, hard drives,
and parallel port. 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:
•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 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 120.
4. If the computer hangs and no error is displayed, go to “Undetermined problems”
on page 130.
5. Power supply problems, see “Power supply LED errors”on page 119.
6. Safety information, see “Safety information”on page 137.
7. For intermittent problems, check the error log; see “Event/error logs”on page 13.
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. IS THE SYSTEM NOT PART OF A CLUSTER?
•Power-off the computer and all external devices.

2 Hardware Maintenance Manual: xSeries 340 Model 6RY
•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 120.
•Check the information LED panel System Error LED; if on, see “Information
panel system error LED”on page 114.
•Check the System Error Log. If an error was recorded by the system,
see“Chapter . Symptom-to-FRU index,”on page 111.
•Start the Diagnostic Programs. See “Starting the diagnostic programs”on
page 14.
•Check 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“Chapter . Symptom-to-FRU index,”on page 111.
YES. Run the Diagnostic Programs. If necessary, refer to “Starting the diagnostic
programs”on page 14.
If you receive an error, go to“Chapter . Symptom-to-FRU index,”on page 111.
If the diagnostics completed successfully and you still suspect a problem, see
“Undetermined problems”on page 130.

•Impressive performance using an innovative approach to SMP
Your server supports up to two Intel Pentium III microprocessors. Your server
comes with one microprocessor installed; you can install an additional
microprocessor to enhance performance and provide SMP capability.
•Large 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. A 3-Pack hard-disk drive option is available to add an additional
three drive bays.
•Optional PCI adapters
Your server uses peripheral component interconnect (PCI) bus architecture to
provide compatibility with a wide range of existing hardware devices and
software applications. Your server supports up to five PCI adapters in the
expansion slots on the system board.
•Redundant cooling capability
The redundant cooling capability of the hot-swap fans in your server allow
continued operation if one of the fans fails. You can also replace a failing hot-swap
fan without turning off the server.
•Optional redundant power capability
You can install an additional 270-watt power supply in your server to provide
redundant power for your server. The Power Non-Redundant 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.
•Large system memory
The memory bus in your server supports up to 4GB 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) (Intel PC-Registered SDIMM Specifications, Revision 1.0 or later).
•System-management capabilities
Your server comes with an Advanced System Management Processor on the
system board. This processor, in conjunction with the Netfinity Manager™
software provided on your ServerGuide CDs, allows you to manage the functions
of the server locally and remotely. The Advanced System Management Processor
also provides system monitoring, event recording, and dial-out alert capability.
Note: The Advanced System Management Processor is sometimes referred to as
the service processor.
•Integrated network environment support
Your 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).
•Redundant 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

6 Hardware Maintenance Manual: xSeries 340 Model 6RY

Diagnostics
This section provides basic troubleshooting information to help you resolve some
common problems that might occur with your server.
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 messages to indicate
successful test completion or the detection of a problem. See “POST”on page 12
for more information.
•Diagnostic 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 13 for more information.
•Light path diagnostics
Your server has light-emitting diodes (LEDs) to help you identify problems with
server components. These LEDs are part of the light-path diagnostics that are
built into your server. By following the path of lights, you can quickly identify the
type of system error that occurred. See “Light path diagnostics”for more
information.
Identifying problems using LEDs
Your server has LEDs to help you identify problems with some server components.
These LEDs are part of the light path diagnostics built into the server. By following the
path of lights, you can identify the type of system error that occurred. See the following
sections for more information.
Power supply LEDs
The AC and DC Power LEDs on the power supply provide status information about
the power supply. See “Power supply LED errors”on page 119.
Light path diagnostics
You can use the light path diagnostics built into your server to quickly identify the
type of system error that occurred. The diagnostics panel is under the "wind tunnel."
Your server is designed so that any LEDs that are illuminated remain illuminated
when the server shuts down as long as the AC power source is good and the power
supplies can supply +5V dc current to the server. This feature helps you isolate the
problem if an error causes the server to shut down. See “Light path diagnostics table”
on page 12.

12 Hardware Maintenance Manual: xSeries 340 Model 6RY
Diagnostics panel
The following illustration shows the LEDs on the diagnostics panel on the system
board. See “Light path diagnostics table”for information on identifying problems
using these LEDs.
Light path diagnostics table
The System Error LED on the operator information panel is lit when certain system
errors occur. If the System Error LED on your server is lit, use the following table to
help determine the cause of the error and the action you should take. See table in
“Information panel system error LED”on page 114.
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, the first screen
of your operating system or application program appears, and the System POST
Complete (OK) light is illuminated on the operator information panel.
If POST detects a problem, more than one beep sounds and an error message appears
on your screen. See “Beep symptoms”on page 111 and “POST error messages”on
page 13 for more information.
Notes:
1. If you have a power-on password 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
