Installing the Processor Extender Board
To install the processor extender board, perform the following steps:
Step 1. Ensure the extraction levers are positioned in the outward, unlocked position.
Step 2. Align the processor extender board with the front and rear card guides.
Step 3. Slide the processor extender board down until it begins to seat in the socket located on the 
midplane riser board.
Step 4. Push the extraction levers inward to the locked position in order to fully seat the processor 
extender board into the socket on the midplane riser board.
Step 5. Replace the front cover. 
Step 6. Replace the front bezel. 
Step 7. If rack mounted, slide the hp Server into the rack until it stops. 
Hot-Swap Chassis Fan Unit
There are three hot-swap chassis fan units in the hp Server. Fan units 0, 1, and 2 are in the center of the 
chassis spanning the full chassis width. Fan units 0 and 1 are interchangeable and are in the left and center 
positions. Fan unit 2 is smaller and only fits into the right-most position (behind the power supply).
CAUTION Observe all ESD safety precautions before attempting this procedure. Failure to follow ESD 
safety precautions could result in damage to the server.
NOTE A hot-swap device does not require interaction with the operating system before the device is 
removed from or installed into the server.
The AC power to the server does not have to be off to remove or replace a hot-swap chassis fan 
unit.
