Chapter 6
Refer to Chapter 2, "Opening and Closing the HP Netserver," to gain
access to the system board.
NOTE It is not necessary to remove the system board from the
Netserver to install the second processor (CPU 2).
6. Loosen the two captive screws holding the air duct over the DIMM slots
and remove the air duct. See Figure 6-2.
7. Ensure the processor speed of the second processor (CPU 2) is the same as
the existing processor before installing the second processor.
NOTE
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 Netserver.
