HP Integrity rx3600 Server User Service Guide

Removing and Replacing the Processor Board Assembly
The processor board assembly holds one or two dual-core Itanium processors, it is located beneath
the disk drives and memory carrier assembly in the bottom service bay. The processor board is
installed onto a removable carrier tray that 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. Power off the server and disconnect the power cables. See “Powering Off the Server”
(page 82).
2. If rack installed, slide the server out from the rack until it stops. See “Extending the Server from
the Rack” (page 164).
3. Unlatch the cover release lever on the top cover and remove the memory carrier assembly
cover. See “Removing the Memory Carrier Assembly Cover” (page 167).
NOTE: You do not need to fully remove the top cover to service this component; however,
the top cover release lever must be open. You must remove the memory carrier because it
attaches directly to the processor board.
4. Remove the memory carrier assembly. See “Removing the Memory Carrier Assembly”
(page 186).
5. Press the button located on top of the bezel and directly in front of the memory carrier assembly
to release the processor board access door (Figure 69).
CAUTION: The processor board access door opens to approximately 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.
6. Use the processor board assembly access door as a handle and gently slide the assembly out
of the chassis approximately six inches.
7. Grasp the handholds on the assembly carrier tray with both hands and carefully slide the
assembly out of the chassis (Figure 69).
