• 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
processors in the appropriate slot.
WARNING! Ensure that the system is powered off and all power sources have been 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: Ensure that processor speed and cache size are identical for all processors. Failure
to observe this caution results in performance degradation or system failure.
To ensure compatibility, HP recommends that you use dual-core processors with identical part
numbers.
CAUTION: Observe all ESD safety precautions before attempting this procedure. Failure to 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 HP 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: Use the supplied handholds to turn the processor board assembly over if you 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 Table 25.

Required Tools
To install and remove processors, use the processor install tool fastened to the processor board.
Installing a Dual-Core Processor
Prior to installing a dual-core processor into the server, read the following instructions carefully
and refer to the figures in this chapter for a complete understanding of this process. To install a
dual-core processor, follow these steps:
1. Remove the memory carrier assembly cover. See “Removing and Replacing the Memory
Carrier Assembly Cover” (page 47). You do not need to fully remove the top cover to service
this component; however, the top cover release lever must be open.
