Removing And Replacing A Dual-Core Processor; Processor Load Order - HP AB464-9003F Service Manual

Removing and Replacing a Dual-Core Processor

The Integrity rx6600 uses dual-core processors. That is, each processor contains two cores that
function as separate processors. Dual-core processors double the processing power of the server
while maintaining the physical dimensions of a single processor.
The server can contain one, two, three, or four dual-core processors that provide the following
configuration options:
1P/2C (One processor/two cores)
2P/4C (Two processors/four cores)
3P/6C (Three processors/six cores)
4P/8C (Four processors/eight cores)
If the server has fewer than the maximum number of dual-core processors installed, install the
additional processors in the appropriate slot.
WARNING!
disconnected from the server prior to performing this procedure.
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 can result in personal injury or damage to equipment.
CAUTION:
to observe this caution results in performance degradation or system failure.
The easiest way to ensure compatibility is to use dual-core processors with identical part numbers.
CAUTION:
follow ESD safety precautions can result in damage to the server.

Processor Load Order

You can install up to four dual-core processors on the processor board. If fewer than the maximum
number of dual-core processors are installed (one, two, or three in the Integrity rx6600 server),
install them in the designated locations on the processor board.
The slots on the processor board are labeled Module 0, Module 1, Module 2, and Module 3. The
Module 0 and Module 1 slots are located on the top of the processor board assembly, and the
Module 2 and Module 3 slots are located on the underside of the processor board assembly.
IMPORTANT:
are servicing the Module 2 or Module 3 slots.
Install the first processor in the Module 0 slot. Install the second dual-core processor in the Module
1 socket, and so on. The load sequence is described in
