Replacing a Processor

To install a processor on the extender board, perform the following steps:
Prior to installing a processor into your system, read the following instructions carefully and refer to Figure 7-15, "Installing
Processor on Extender Board," for a complete understanding of this process.
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.
Step 3. Remove the front cover. See "Front and Top Covers" on page 145.
Step 4. Remove the memory extender board. See "Memory Extender Board" on page 151.
Step 5. Using an antistatic wrist strap place the extender board ona grounding mat (Electrically Conductive Field Service
Grounding Kit-HP 9300-1155).
Step 6. Ensure the cam on the processor socket lock is in the unlocked, counterclockwise position.
Step 7. Carefully lower the processor, without the sequencer clamp, onto the processor socket. Align the pins on the
bottom of the heatsink to the slots in the retention frame on the extender board.

Step 8. Lock the assembly to the socket by rotating the cam on the socket 180 degrees clockwise, using a 2.5 mm driver
(Allen wrench).
Chapter 7
Test the alignment of the assembly to the socket by gently moving the assembly back and forth
with the palm of your hand—you should feel little or no sideplay. However, because the assembly
is not yet tightened, it may tilt slightly towards the center of the extender board—this is
acceptable.
Before locking the processor assembly into its socket, ensure that the power cable is not pinched
between the heatsink and sheetmetal frame of the extender board. Also, ensure that the two power
supply cable ends attached to the CPU assembly do not come unplugged from their sockets when
you move the cable into place under the heatsink. See Figure 7-13, "Processor Cable Placed
Correctly," and Figure 7-14, "Processor Cable Placed Incorrectly."
