2. Identify the location of the faulty processor by pressing the Fault Remind
button on the motherboard.
Note – When the Fault Remind button is pressed, a LED located next to the Fault
Remind button lights green to indicate that there is sufficient voltage present 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 has lost its charge. This can happen if the Fault
Remind button is pressed for a long time with fault LEDs lit or if power has been
removed from the server for more than 15 minutes.
The processor fault LEDs are located next to the processor(s).
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 should
■
be replaced.
Note – Processor 0 (P0) is on the left side when viewing the server from the front.
