PCI riser card
The peripheral component interface (PCI) riser card extends upward, and at a right angle, from the
main card. The PCI riser card provides a PCI for the MSC and field-installed WAN cards.

Figure 15 shows the PCI connectors without the MSC or WAN cards. Two screws at the top of the
PCI riser card attach the card to the side of the base function tray.
