Replacing 3.3-Volt and 5-Volt Add-in Cards in Low Profile, Half-

Length PCI Adapter Subsystem

A three-slot PCI adapter assembly that supports only low-profile, half-length PCI adapters is installed in the

Segment C PCI riser slot located on the right side of the server baseboard. This PCI adapter assembly is

configured and installed as shown in Figure 11-17. After the PCI adapter assembly is removed from the

server, it is configured with PCI adapters by plugging the PCI adapters into the PCI connectors on the 3.3-

Volt riser card that is part of the PCI adapter assembly. The PCI adapter assembly is then installed into the

server by plugging the riser card into the riser card connector on the server baseboard. In addition, it is

necessary to make sure that the interlocking metal tabs on the back of the PCI adapter assembly are

correctly inserted into the slots in the back of the chassis.

Table 11-6 shows the maximum PCI bus speed achievable on PCI Bus Segment C. Any slower PCI adapter

installed in the PCI adapter subsystem will gate the speed.
