Removing a Dual Processor Module
WARNING!
Ensure that the system is powered off and all power sources have been disconnected
from the server before removing or replacing a processor.
Voltages are present at various locations within 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.

1. If rack-mounted, slide the server out from the rack until it stops. (See “Accessing a
Rack-Mounted Server” (page 149) .)
2. Remove the front bezel. See “Removing the Front Bezel” (page 152) .
3. Remove the front cover. See “Removing the Front Cover” (page 152) .

6. Using a Torx T15 driver, loosen the four T15 shoulder screws and the two knurled
thumbscrews that attach the sequencer frame on the heatsink, until the sequencer frame is
free.
7. Remove the sequencer frame from the heatsink.
8. Using a CPU Install Tool, unlock the assembly from the socket by rotating the cam on the
socket 180 degrees counterclockwise.
