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 port. Not all servers
include all of these items; your hardware might differ. You can also use the
diagnostic programs to test some external devices. See “Diagnostic programs and
error messages” on page 15.
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 server might be part of a shared DASD cluster (two or more servers
sharing the same external storage device(s)). Prior to running diagnostics, verify
that the failing server is not part of a shared DASD cluster.
A server might be part of a cluster if:
v The customer identifies the server as part of a cluster.
v One or more external storage units are attached to the server and at least one of
the attached storage units is additionally attached to another server or
unidentifiable source.
v One or more servers are located near the failing server.
If the failing server 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 servers 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 server stops working with a POST error, go to “Symptom-to-FRU index”
on page 115.
4. If the server stops working and no error is displayed, go to “Undetermined
problems” on page 143.
5. For information about power supply problems, see “Power supply LED errors”
on page 133.
6. For safety information, see “Safety information” on page 145.
7. For intermittent problems, check the error log; see “Error logs” on page 14.

001 IS THE SERVER PART OF A CLUSTER?
YES. Schedule maintenance with the customer. Shut down all servers
related to the cluster. Run storage test.
NO. Go to step 002.
002 IF THE SERVER IS NOT PART OF A CLUSTER:
v Turn off the server and all external devices.
v Check all cables and power cords.
v Set all display controls to the middle position.
v Turn on all external devices.
v Turn on the server.
v 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 134.
v Check the diagnostic LED panel system error LED; if on, see “Level 2
Light Path Diagnostics” on page 19.
v Check the System Error Log. If the server recorded an error, see
“Symptom-to-FRU index” on page 115.
v Start the diagnostic programs. See “Diagnostic programs and error
messages” on page 15.
v Check for the following responses:
1. One beep.
2. Readable instructions or the Main Menu.
003
DID YOU RECEIVE BOTH OF THE CORRECT RESPONSES?
NO. Find the failure symptom in “Symptom-to-FRU index” on page 115.
YES. Run the diagnostic programs. If necessary, see “Diagnostic programs
and error messages” on page 15.
If you receive an error, go to “Symptom-to-FRU index” on page 115.
If the diagnostics completed successfully and you still suspect a problem,
see “Undetermined problems” on page 143.

What the xSeries 360 offers
The design of the server takes advantage of advancements in symmetric
multiprocessing (SMP), data storage, disk-array technologies, and memory
management. The server combines:
v X-Architecture technology
X-Architecture technology is an IBM design blueprint that takes full advantage of
existing IBM technologies to build powerful, scalable, and reliable Intel
processor-based servers.
For more information about X-Architecture technology, go to the Web at
http://www.pc.ibm.com/us/eserver/xseries/xarchitecture/index.html.
v Impressive performance using an innovative approach to SMP
The server supports up to four Intel Xeon Processor MP
™
microprocessors. The
server comes with at least one microprocessor installed; you can install additional
processors to enhance performance and provide SMP capability.
v Large data-storage and hot-swap capabilities
The xSeries 360 server supports up to three 26 mm (1-inch) slim-high 3.5-inch
hot-swap hard disk drives in the hot-swap bays. This hot-swap feature enables
you to remove and replace hard disk drives without turning off the server.
v Active PCI-X (hot-plug) adapter capabilities
The server has six hot-plug PCI-X slots for PCI or PCI-X adapters. With
operating-system support, you can replace failing hot-plug PCI/PCI-X adapters
without turning off the server. If the hot-add feature is supported by both the
operating system and a PCI/PCI-X adapter, you can also add such PCI/PCI-X
adapters in these slots without turning off the server.
v Redundant hot-swap cooling and redundant hot-swap power capabilities
The fans in the server can operate at variable speeds so that if one fan fails, the
remaining fans increase in speed to enable continued operation until the failing
fan is replaced. You can replace a failing fan without turning off the server.
The server supports up to three 370-watt power supplies. Multiple hot-swap
370-watt power supplies ensure redundancy and hot-swap capability for a typical
configuration.
v Large system memory
The memory bus in the server supports up to 8 GB of system memory. The
memory controller provides error correcting code (ECC) support for up to eight
industry-standard, 2.5 V, 168-pin, 16-byte, PC1600 registered DDR SDRAM dual
inline memory modules (DIMMs). The memory controller also provides Chipkill

server from a single chip failure on a DIMM.
Features overview 5

v Light Path Diagnostics
Light Path Diagnostics provide LEDs to assist in isolating problems with the
server. An LED on the operator information panel is lit if an unusual condition or
a problem occurs. If this happens, you can look at the LEDs visible through a
special cutout in the cover and isolate the cause. Under some circumstances,
you might need to remove the cover and view LEDs on the system board to
pinpoint the source of a problem.
v Systems-management capabilities
The server comes with a Remote Supervisor Adapter installed. This adapter, in
conjunction with the systems-management software provided with the server,
enables you to manage the functions of the server both locally and remotely. The
Remote Supervisor Adapter also provides system monitoring, event recording,
and dial-out alert capability.
v Integrated network environment support
The server comes with an Ethernet controller integrated into 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 enables
simultaneous transmission and reception of data on the Ethernet local area
network (LAN).
v Remote expansion enclosure
The addition of an optional, IBM RXE-100 Remote Expansion Enclosure provides
up to twelve additional hot-plug PCI/PCI-X slots for PCI or PCI-X adapters. The
enclosure can be managed through the Remote Supervisor Adapter, enabling
remote operation over a network or a modem.
v Redundant network adapter
The addition of an optional, redundant network adapter provides a failover
capability to a secondary 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 network adapter. If the
appropriate device drivers are installed, this switching occurs without data loss
and without user intervention.
v IBM ServerGuide
™
CDs
The ServerGuide
™
CDs that are 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 installed hardware options and provides the
correct configuration programs and device drivers. In addition, the ServerGuide
CDs include a variety of application programs for the server.
Note: The latest level of basic input/output system (BIOS) code for the server is
available through the World Wide Web. See “Recovering the BIOS code”
on page 18 for more information.

Note: If this LED is off, it does not mean that there is no electrical power present in
the server. The LED might be burned out. To remove all electrical current
from the server, you must unplug the server power cords from the electrical
outlets.
Turning on the server
Turning on the server refers to the act of plugging the server power cords into the
power source and pressing the power-control button. After you install the network
operating system in the server, this typically causes the operating system to start.
Complete the following steps to turn on the server.
1. Turn on all external devices, such as the monitor.
Note: After you plug the power cords into the power source, wait 30 seconds
before pressing the power-control button on the operator information
panel. During this time, the Remote Supervisor Adapter is initializing and
the power-control button does not respond. The power LED on the
information panel blinks, indicating that ac power is present in the server.
2. Plug the server power cords into the power source.
Note: Plugging the power cords into the power source might cause the server
to start automatically. This is an acceptable action.
3. Wait 30 seconds; then, press the power-control button on the operator
information panel. The power LED comes on and the power-on self-test (POST)
begins.
