Installing A Second Processor - HP ProLiant ML150 Operation Manual

Installing a Second Processor

This section provides the instructions for installing a second processor and its heatsink on the
system board. Figure 2-14 indicates the location of the primary and secondary processors.
1. Unpack the processor shipping box and check the contents against its packing list.
2. Log off all users, back up files, and shut down the NOS according to the instructions in
your NOS documentation.
3. Press the power switch on the HP server control panel when prompted by the operating
system.
Normally, this completes the shutdown procedure.
4. Disconnect the AC power cord.
5. Open the side panel and lay the chassis down to gain access to the system board.
NOTE: It is not necessary to remove the system board from the server to install the second processor
(CPU 2).
6. Be sure the processor speed of the second processor (CPU 2) is the same as the primary
processor.
If you are upgrading the second processor to a faster processor speed than the primary
processor, the primary processor must also be changed. Both processors must have the
same product number, which includes the same clock speed, cache size, and FSB speed.
The supported processors only perform at the rated speed indicated on the processor in
the HP server.

CAUTION: Take the following precautions when installing processors:
•
Leave the processor in the anti-static bag until you are ready to install it.
•
Wear an anti-static wrist strap and use a static-dissipating work surface or grounding mat
connected to the chassis when handling components.
•
Before removing a processor from the anti-static bag, touch a grounded, unpainted metal
surface to discharge static electricity.
WARNING: Power supplies continue to provide standby current to the HP server until
the power cord is disconnected.
