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 4-17, "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. (Refer to the hp9000 rp4440
Installation Guide for additional information.)
Step 2. Remove the front bezel. (Refer to "Front Bezel" on page 38.)
Step 3. Remove the front cover. (Refer to "Front and Top Covers" on page 39.)
Step 4. Remove the processor extender board and place on anti-static mat. (Refer to "Processor Extender
Board" on page 53.)
Step 5. Ensure the cam on the processor socket lock is in the unlocked, counterclockwise position.
Step 6. 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.

Chapter 4
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 sheet metal frame of the extender board. Also,
ensure that the two power 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 4-15 on page 60and Figure 4-16 on page 60.
