Processors
Processors are located on the top and bottom surfaces of the processor extender board.
WARNING Ensure that the system is powered down and all power sources have been disconnected from the server
prior to removing or replacing a processor.
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 could result in personal injury or damage to equipment.
Installing Processors
CAUTION Ensure that the cache size is identical for all processors. Failure to observe this caution will result in system
failure.
Ensure that all processors are rated for use at the same speed. Failure to observe this caution will result in
performance degradation.
Processor Load Order
Processor moduless are housed on the processor extender board located under the top cover in the top service bay. The
processor extender board can hold between one and four processor modules. CPU 0 and CPU 1 are located on the top of the
processor extender board and CPU 2 and CPU 3 are located on the bottom. Processors must be installed in a specific order.
CAUTION Do not modify the settings of the DIP switches located on the processor extender board. These switches are
for factory use. Failure to observe this caution will result in system failure.
Removing a Processor
To remove a processor on the processor extender board, perform the following steps:
Step 1. If rack mounted, slide the HP Server out from the rack until it stops. See “Accessing a Rack Mounted Server” on
page 141.
Step 2. Remove the front bezel. See “Front Bezel” on page 144.
