Processor Expansion Module

NOTE: After installing a new power supply in a system with two power supplies, allow several seconds for the system to recognize the power supply and determine its status. The power-supply status indicator turns green to signify that the power supply is functioning properly (see Figure 1-4).

There are two types of processor expansion module assemblies used with your system:

•If you have a four-processor system, the processor expansion module (PEM) contains a processor expansion module board with two processor sockets and 16 memory module sockets.

•If you have a two-processor system, the processor expansion module shell (PEM shell) contains an air baffle.

NOTICE: The PEM shell must be installed in a two-processor system to ensure adequate cooling airflow within the system.

Removing the PEM or PEM Shell

CAUTION: Only trained service technicians are authorized to remove the system cover and access any of the components inside the system. See your Product Information Guide for complete information about safety precautions, working inside the computer, and protecting against electrostatic discharge.

1Turn off the system, including any attached peripherals, and disconnect the system from the electrical outlet.

2Open the system. See "Opening the System" on page 65.

3Lift the handle on the PEM until the PEM is fully disengaged from the chassis. See Figure 3-7
