Damaged data in CMOS memory or damaged firmware can cause undetermined
problems. To reset the CMOS data, use the password switch 2 (SW4) to override
the power-on password and clear the CMOS memory; see "System-board switches
and jumpers" on page 27.
Check the LEDs on all the power supplies (see "Power-supply LEDs" on page 31).
If the LEDs indicate that the power supplies are working correctly, complete the
following steps:
1. Turn off the server.
2. Make sure that the server is cabled correctly.
3. Remove or disconnect the following devices, one at a time, until you find the
The following minimum configuration is required for the server to start:
v One microprocessor
v One 1 GB DIMM
v One power supply
v Power cord
v ServeRAID SAS adapter
v System board assembly
4. Turn on the server. If the problem remains, suspect the following components in
If the problem is solved when you remove an adapter from the server but the
problem recurs when you reinstall the same adapter, suspect the adapter; if the
problem recurs when you replace the adapter with a different one, suspect the
system board or extender card.
If you suspect a networking problem and the server passes all the system tests,
suspect a network cabling problem that is external to the server.
Event logs
Error codes and messages are displayed in the following types of event logs:
v POST event log: This log contains the three most recent error codes and
v System-event log: This log contains all IMM, POST, and system management
failure. Turn on the server and reconfigure it each time.
v Any external devices.
v Surge-suppressor device (on the server).
v Modem, printer, mouse, and non-IBM devices.
v Each adapter.
v Hard disk drives.
v Memory modules. The minimum configuration requirement is 1 GB DIMM per
microprocessor (2 GB in a two-microprocessor configuration).
the following order:

b. Power-supply cage
c. Memory
d. Microprocessor
e. System board

interrupt (SMI) events. You can view the system-event log through the Setup
utility and through the Dynamic System Analysis (DSA) program (as the IPMI
event log).
The system-event log is limited in size. When it is full, new entries will not
overwrite existing entries; therefore, you must periodically save and then clear
