Identify and Remove a Faulty Processor
See “Preparing for Service” on page 97 .
2.
Identify the location of the faulty processor by pressing the Fault Remind button
on the CMOD motherboard.
Note -
When you press the Fault Remind button, an LED located next to the Fault Remind
button lights green, indicates that there is sufficient voltage in the fault remind circuit to light
any fault LEDs that were lit due to a failure. If this LED fails to light when you press the Fault
Remind button, it is likely that the capacitor powering the fault remind circuit lost its charge.
This can happen if you press the Fault Remind button for a long time with the fault LED lit, or
if power was removed from the server for more than 15 minutes.
The processor fault LED that is located adjacent to the faulty processor lights:
■
If the processor fault LED is off, then the processor is operating properly.
■
If the processor fault LED is on (amber), then the processor is faulty and must be replaced.
