System Board Features

The system board functions as the main interface between the processor,
memory, and peripherals.

Table 1 lists the features of the system board. Figure 3 on page 11 shows the
components on the system board and their locations.

System Board Connectors

Figure 3 shows the connectors on the system board. Some of these
connectors may not be used, depending on the configuration of the server.
The table below provides the key to Figure 3.
