8.
Slide the processor board assembly into the chassis until it begins to seat into the socket located
on the midplane board.
9.
Push the processor board access door upward until it locks into position.
10. Replace the memory carrier assembly. See
“Replacing the Memory Carrier Assembly”
(page 204)
.
11. Replace the memory carrier assembly cover. See
“Replacing the Memory Carrier Assembly
Cover” (page 180)
.
12. Close the top cover release lever.
13. If rack installed, slide the server completely into the rack. See
“Inserting the Server into the
Rack” (page 177)
.
14. Reconnect the power cables and power on the server. See
“Powering On the Server” (page 90)

Removing and Replacing the Processor Board Assembly
The processor board assembly holds one, two, three, or four dual-core Itanium processors. It is
located beneath the disk drives and memory carrier assembly in the bottom service bay. The
processor board is mounted 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 90)
.
2.
If rack installed, slide the server out from the rack until it stops. See
“Extending the Server from
the Rack” (page 176)
.
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 179)
.
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 203)
.
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 72
).
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.
