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.
1.
Determine if the Service Required LEDs are lit on the front panel or the rear I/O
module.
See “Interpreting LEDs” on page 29 .
2. From the front of the server, check the processor module LEDs to identify which
processor module needs to be replaced.
See “Processor Module LEDs” on page 61 .
3. Remove the faulty processor module.
See “Remove a Processor Module or Processor Filler Module” on page 63 .
