Remove a Processor
Remove a Processor
Caution -
The green color-coded processor removal and replacement tool (part number
G29477-002 or later) must be used to remove the 8-core processor; otherwise, the processor or
the processor socket might be damaged.
Caution - Be careful not to touch the processor socket pins. The processor socket pins are
very fragile. A light touch can bend the processor socket pins beyond repair. Always use the
processor removal/replacement tool to remove and replace the processor.
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 51 .
b. Attach an antistatic wrist strap to your wrist, and then to a metal area on the
chassis.
See “Take Antistatic Measures” on page 57 .
c.
Extend the server to the maintenance position.
See “Extend the Server to the Maintenance Position” on page 55
d. Remove the server top cover.
See “Remove the Server Top Cover” on page 58 .
e. Swivel the air baffle into the upright position to allow access to the
processors.
2. Identify the location of the faulty processor by pressing the Fault Remind button
on the motherboard I/O card.
Note -
When the Fault Remind button is pressed, an 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.
