processor board is mounted onto a removable carrier tray, which is retained in the service bay
by a hinged access door.
WARNING! Ensure that the system is powered off and all power sources have been disconnected
from the server prior to performing this procedure.
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.
CAUTION: Observe all ESD safety precautions before attempting this procedure. Failure to follow
ESD safety precautions can result in damage to the server.
Removing the Processor Board Assembly
To remove the processor board assembly, follow these steps:
1. Unlatch the cover release lever on the top cover and remove the memory carrier assembly
cover. See “Removing and Replacing the Top Cover” (page 46). You do not need to fully
remove the top cover to service this component; however, the top cover release lever must be
open.
2. Remove the memory carrier assembly. See “Removing and Replacing the Memory Carrier
Assembly Cover” (page 47).
NOTE: You must remove the memory carrier because it attaches directly to the processor
board.
3. Press the button located on top of the bezel, directly in front of the memory carrier assembly
to release the processor board access door (Figure 29).
CAUTION: The processor board access door opens at a 30 degree angle. Do not force the
door to open to a greater angle. Failure to observe this warning results in damage to server
components.
4. Use the processor board assembly access door as a handle and gently slide the assembly out
of the chassis approximately six inches.
5. Grasp the handholds on the assembly carrier tray with both hands and carefully slide the
assembly out of the chassis (Figure 29).
