System Board Configuration
Refer to the following sections for instructions on how to remove or replace the processors,
the memory modules, the expansion boards, and the system battery.
Processor
The server’s two 940-pin processor sockets support single- and dual-core AMD Opteron
processors. The location of the server’s two processor sockets (U11 and U22) is shown in
Figure 2-31.

Guidelines for Installing a Processor
When installing a processor in the server, observe the following important guidelines:
•
Processor socket 1 (U22) must always be populated. If no processor is installed in this
socket, the system will fail to boot and halt during POST. This error prevents the system
from functioning properly.
The default system comes with a single processor installed in the processor socket 1. The
empty processor socket 2 is protected by an air baffle.
