6.4 Expanding the Server Unit
6.4.5 Adding PCI cards
There are three types of PCI card: a PCI card designed to operate in 3.3V slots, a PCI card designed to operate in
5V slots, and a PCI (universal) card design to operate in both 3.3V and 5V slots. Though most PCI cards operate
at a 33MHz clock, some cards operate at a 66MHz clock.
Refer to Table 6.5 and Figure 6.9 below for details of the PCI slot positions when installing PCI cards.
