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
1.
Determine if the Service Required LEDs are illuminated on the front panel or the
rear I/O module.
See “Interpreting LEDs” on page 28.
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 60. The amber Service Required LED is lit on the
processor module that needs to be replaced.
3.
Remove the faulty processor module.
See “Remove a Processor Module or Processor Filler Module” on page 61.

Remove a Processor Module or Processor Filler Module
Processor modules and processor filler modules are cold-service components that can be
replaced only after you power off the system. For the location of the modules, see “Processor
Module Locations” on page 59.
Caution - The server can overheat if you leave the server running with the empty processor
module slot open for longer than one minute. To ensure proper airflow, leave the faulty
processor module installed if a replacement processor module or processor filler module is
currently unavailable.
Processor modules are cold-service components that can be replaced only by qualified service
personnel.
