Troubleshooting


Problem

If the system-error LED on your BladeCenter HS20 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 HS20 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 HS20 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 both DIMMs in the bank.
  3. Check for a memory type mismatch in the bank.
  4. Run the diagnostic programs.

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.
IDE bus x error The IDE bus indicated by the error LED has failed.
  1. Reseat/replace the hard disk drive on IDE bus x.
  2. Replace the system 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.
