Single-Core to Dual-Core Processor Upgrade Guide. First Edition - HP Integrity rx2620 (September 2006)

Upgrading the Processors in the Server

Upgrading the Server to Dual-Core Processors

Chapter 1

CAUTION Ensure that the cache size is identical for all processors. Failure to observe this caution will

result in server failure.

Ensure that all processors are rated for use at the same speed. Failure to observe this caution

will result in performance degradation.

Valid processors are identified in the Parts Information chapter of the HP Integrity rx2620

Maintenance Guide.

Step 11. Ensure the ZIF socket processor locking mechanism is unlocked using the CPU install tool, or

equivalent 2.5 mm hex tool. Insert the tool into the lock and rotate the special processor tool 180

degrees counterclockwise. Verify that the ZIF socket is rotated into the unlocked position.

Figure 1-17 shows how to unlock the ZIF socket.

CAUTION The ZIF socket for the processor is locked and unlocked by 1/2 of a full turn of the

CPU install tool. The counterclockwise 180 degree rotation (1/2 turn) unlocks the

socket. A clockwise 180 degree rotation locks the socket. Attempting to turn the

locking mechanism more that 180 degrees will severely damage the socket.

Step 12. Use the two alignment pins on the processor to properly align the processor on the system board.

The two alignment pins fit in the alignment holes on the system board processor mount. The turbo

fan power cable must be positioned so that it is located on the side of the heatsink that faces the

front of the server. Figure 1-18 shows the alignment pins on the processor.

NOTE For the dual-core processors, the power pod and processor are a single assembly.
