Option Boards

This section describes how to install and remove PCI option boards. The PCI
I/O board plugs into the system board and has four PCI bus expansion slots. The
PCI I/O board is shown in Figure 4-22. Option boards plugged into PCI slots 1,
2, and 3 may be accessed from the rear of the system in order to connect
external cables. An option board plugged into PCI slot 4 is reserved for boards
that do not require external cable connections. PCI 4 may be used for installing
a RAID controller. Refer to Table 4-1 for recommended PCI option board
locations.
