Determine Which Processor Module Is Faulty
The following LEDs are lit when a processor module fault is detected:
Front and rear System Fault (Service Required) LEDs
Service Required LED on the faulty processor module
Note - A faulty processor module at PM0 results in server shutdown and failure to reboot. If your server experiences a fault at PM0 and you do not have a replacement processor module available, you can move one of the other processor modules to PM0 and then boot the server in a degraded state.
 | Caution - In order to maintain system cooling, all four processor module slots must be occupied either with a processor module or a processor filler module. |
- Determine
if the Service Required LEDs are lit on the front panel or the rear
I/O module.
See Interpreting LEDs.
- From the front of the server, check the processor module LEDs to identify which processor module needs to be replaced.
- Remove the faulty processor module.
