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:
1 Perform the pre-installation instructions described on page 37.
2 Lay the server on its side (components showing).
3 Disconnect the processor 1 HSF cable from its mainboard
connector.
