Troubleshooting light path diagnostics table - IBM BladeCenter HS40

Troubleshooting


Problem

If the system-error LED on your BladeCenter HS40 unit is lit, use the following table to help determine the cause of the error and the action you should take.

Resolving The Problem

The system-error LED on the system LED panel is lit when certain system errors occur. If the system-error LED on your BladeCenter HS40 unit is lit, use the following table to help determine the cause of the error and the action you should take.

Lit LED
Cause
Action
BladeCenter HS40 system LED panel
None
An error has occurred and cannot be isolated, or the service processor has failed.
An error has occurred that is not represented by a Light Path Diagnostics LED. Check the system error log for more information about the error.
Processor x error
The microprocessor has failed.
  1. Verify that the microprocessor indicated by the lit LED is installed correctly.
  2. Replace the microprocessor.
Memory/DIMM error
A memory error occurred.
  1. If a memory problem occurs, take the following actions before replacing a DIMM.
  2. Reseat the DIMM indicated by the lit DIMM failure LED.
  3. Replace the DIMM.

Note: Multiple DIMM LEDs do not necessarily indicate multiple DIMM failures. If more than one DIMM LED is on, reseat/replace one DIMM at a time until error goes away. Refer to the BladeCenter management module system error log for further isolation.
Temperature error
The system temperature has exceeded a threshold level.
  1. Check to see if a blower on the BladeCenter unit has failed. If it has, replace the fan.
  2. Make sure the room temperature is not too high.

Note: Air temperature:

  • Blade server on: 10° to 35°C (50° to 95°F). Altitude: 0 to 914 m (2998.69 ft)
  • Blade server on: 10° to 32°C (50° to 95°F). Altitude: 914 m to 2134 m (2998.69 ft to 7000 ft)
  • Blade server off: -40° to 60°C (-40° to 140°F)
System board error
The system board has failed
  1. Replace the blade server cover, reinsert the blade server in the BladeCenter unit, and then restart the server.
  2. Replace the system board.
I/O board fault
The integrated VRM on the blade server I/O board has failed.
  1. Replace the blade server cover, reinsert the blade server in the system chassis, and then restart the blade server..
  2. Replace the I/O board.
BMC fault
The BMC self-test has detected a failure.
  1. Reset and initialize the blade server and I/O board.
  2. Replace the I/O board.
NMI error
The system board has failed.
  1. Replace the blade server cover, reinsert the blade server in the BladeCenter unit, and then restart the blade server.
  2. Check the system error log for information about the error.If the problem remains, replace the system board.
Processor mismatch
The processors do not match.
Verify that microprocessors 1 and 2 have the same cache size and type and the same clock speed. Internal and external clock frequencies must be identical.
