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 3.3Volt 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. Figure 11-17.

Any slower PCI adapter installed in the PCI adapter subsystem will gate the speed. Table 11-6.
