Replacing 3.3 Volt And 5 Volt Pci Add-In Cards In Full-Length Pci Adapter Subsystem; Figure 33. Segment B Full-Height, Full-Length Pci Adapter Subsystem; Table 26. Segment B Full-Height, Full-Length Pci Adapter Maximum Speed - IBM @server xSeries 343 Product Manual

Replacing 3.3 Volt and 5 Volt PCI Add-in Cards in Full-
Length PCI Adapter Subsystem
This PCI adapter assembly is configured and installed as shown in Figure 33. After the PCI adapter
assembly is removed from the system, it is configured with PCI adapters by plugging the PCI adapters
into the PCI connectors on the riser card (either a 3.3-Volt riser card or a 5-Volt riser card) that is part
of the PCI adapter assembly. The PCI adapter assembly is then installed into the system 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 26 shows the maximum PCI bus speed achievable on PCI Bus Segment B. Any slower PCI
adapter installed in the PCI Adapter Subsystem will gate the speed.
