Event logs

Check the LEDs on all the power supplies. If the LEDs indicate that the power supplies are working correctly, do the following:

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 failure. Turn on the server and reconfigure it each time.

•Any external devices

•Surge-suppressor device (on the server)

•Modem, printer, mouse, and non-Lenovo devices

•Each adapter

•Hard disk drives

•Memory modules: the minimum configuration requirement is 1 GB DIMM per microprocessor (2 GB in a two-microprocessor configuration)

The following minimum configuration is required for the server to start:

•One microprocessor

•One 1 GB DIMM

•One power supply

•Power cord

•ServeRAID SAS adapter

•System board assembly

4.Turn on the server. If the problem remains, suspect the following components in the following order: a. Power supply

b. Power-supply cage c. Memory

d. Microprocessor e. System board

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.

Error codes and messages are displayed in the following types of event logs:

•POST event log: This log contains the three most recent error codes and messages that were generated during the POST.

•System-event log: This log contains all the POST and system management interrupt (SMI) events. You can view the system-event log through the Setup Utility program and through the 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 the system-event log through the Setup Utility program. When you are troubleshooting, you might have to save and then clear the system-event log to make the most recent events available for analysis.
