Event logs, System event log | Lenovo TD230 instruction

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 2 GB DIMM

•One power supply

•Power cord

•Server RAID 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.

Event logs

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.

System event log

The BMC implements the system event log (SEL) as specified in the Intelligent Platform Management Interface Specification, Version 2.0. The SEL is accessible regardless of the system power state via the BMC's in-band and out-of-band interfaces.

Diagnostic programs and messages

Whenever possible, the BIOS outputs the current boot progress codes on the video screen. Progress codes are 32-bit quantities plus optional data. The 32-bit numbers include class, subclass, and operation information. The class and subclass fields point to the type of hardware being initialized. The operation field represents the specific initialization activity. Based on the data bit availability to display progress codes, a
