Upgrading the processor

This section explains the procedures for removing and installing the processor and heat sink fan (HSF) assembly.

Processor configuration guidelines

The mainboard has two LGA771 processor sockets supporting Dual-Core Intel Xeon processors. You have the option to upgrade the default processor or install a second one for a dual-processor configuration.

Observe the following guidelines when replacing or installing a processor.

•The CPU 1 socket must always be populated. If no processor is installed in this socket, the system will fail to boot.

•Before removing a processor, make sure to back up all important system files.

•When installing a second processor, make sure it has same stepping and frequency specifications as the default processor.

•Handle the processor and the HSF assembly carefully. Damage to either may prevent the system from functioning properly.

Note: A long-nosed screwdriver is needed to remove/install the HSF assembly.

To upgrade the default processor:

1Perform the pre-installation instructions described on page 37.

2Lay the server on its side (components showing).

3Disconnect the processor 1 HSF cable from its mainboard connector.
