6. Ensure 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 Netserver.
CAUTION Always wear a wrist strap and use a static-dissipating work
surface connected to the chassis when handling components.
Ensure the metal of the wrist strap contacts your skin.
7. Open the ZIF (Zero Insertion Force) lever. Then lift the terminator out of the
socket and place it on anti-static surface or container. See Figure 6-2.
To open the ZIF lever, pull the lever out away from the ZIF socket and raise
it 90
° to the system board.
