WARNING!
Ensure that the system is powered off and all power sources are disconnected
from the server prior to performing this procedure.
Voltages are present at various locations in the server whenever an ac power source is connected.
This voltage is present even when the main power switch is in the off position.
Failure to observe this warning can result in personal injury or damage to equipment.
CAUTION:
Ensure that processor speeds and cache sizes are identical for all processors. Failure
to observe this caution causes performance degradation or system failure.
The easiest way to ensure processor compatibility is to use processors with identical part numbers.
CAUTION:
Observe all ESD safety precautions before attempting this procedure. Failure to
follow ESD safety precautions can result in damage to the server.
Processor Load Order
The server supports up to two processors on the processor board. The slots on the processor
board are labeled CPU 0 and CPU 1. In single-processor servers, you must install the processor
in the CPU 0 slot. In dual-processor servers, you must install the second processor in the CPU 1
slot.
Table 6-3
lists the processor load sequence.

Required Tools
To install and remove processors, use the processor install tool fastened to the airflow guide.
Removing a Processor
To remove a processor, follow these steps:
1.
Power off the server and disconnect the power cables. See
“Powering On and Powering Off
the Server” (page 78)
.
2.
If rack mounted, slide the server out from the rack until it stops. See
“Extending the Server
from the Rack” (page 143)
.
3.
Remove the top cover. See
“Removing the Top Cover” (page 144)
.
4.
Remove the airflow guide. See
“Removing the Airflow Guide” (page 146)
.
5.
Open the processor cage.
a.
Grasp the processor cage handle and apply adequate force to rotate the handle upward.
See
Figure 6-28
.
b.
Use the handle to rotate the cage closure approximately 90 degrees toward the front of
the server until it stops. See
Figure 6-29
.
IMPORTANT:
Ensure the processors are entirely exposed and can clear the cage
enclosure for removal.
6.
Disconnect the processor power cable from the connector cable attached to the system board.
See
Figure 6-30
.
7.
Unlock the processor from the socket on the processor board. See
Figure 6-31
.
