Replacing 3.3 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 34. 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 3.3-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 27 shows the maximum PCI bus speed achievable on PCI Bus Segment C. Note that only 3.3-V
PCI riser cards are supported in the Segment C PCI Adapter Subsystem. 5-V PCI riser cards are not
supported.
