Identify and Remove a Processor
Caution -
Whenever you remove a processor, replace it with another processor and reinstall the
processor heatsink; otherwise, the server might overheat due to improper airflow. See “Install a
Processor” on page 130 .
1. Prepare the server for service.
a. Power off the server and disconnect the power cords from the power
supplies.
See “Powering Down the Server” on page 53 .
b. Attach an antistatic wrist strap to your wrist, and then to a metal area on the
chassis.
See “Take Antistatic Measures” on page 63 .
c. Extend the server to the maintenance position.
See “Extend the Server to the Maintenance Position” on page 60 .
d. Remove the server top cover.
See “Remove the Server Top Cover” on page 64 .
e. Remove the air baffle.
See “Remove the Air Baffle” on page 95 .
2. Identify the location of the failed processor by pressing the Fault Remind button
on the motherboard.
Note -
When you press the Fault Remind button, an LED located next to the Fault Remind
button lights green, indicating 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 fault LEDs lit, or if
power was removed from the server for more than 15 minutes.
The processor fault LED for the failed processor lights. The processor fault LEDs are located
next to the processors. See “Motherboard Status Indicators” on page 35 .
■
If the processor fault LED is off, the processor is operating properly.
