Front Cards
The following module configurations are supported for the PXM45:
•Standalone.
•Card set redundancy (Y-cable).
Note For module configuration information, refer to Chapter4, “Planning for Card Redunda ncy, Line
Redundancy, and Bulk Distribution”.
RPM-PR

Supported models: MGX 8850 (PXM1E/PXM45), MGX 8850/B (PXM1E/PXM45), MGX 8950, MGX 8830, MGX 8830/B, MGX8880

The RPM-PR is a double-height service module that provi des integrated IP on an ATM platform,
enabling services such as integrated Point-to-Point protocol (PPP).
The RPM-PR:
•Provides an ATM interface to the switch and supports up to two port adapters, a four-port Ethernet
(10BASE-T), and a one-port Fast Ethernet (unshielded twisted pair [UTP], MMF)
•Has a QED RM7000 processor subsystem that provides over 350 kilo packets per second (kpps) of
throughput for IP packet forwarding
•Provides integrated IP in an ATM platform
•Has an attached daughter card that contains the processing intelligence and contains the firmware
that determines the interface type (OC-3c, OC-12c, T3, E3, and so forth)
When the RPM-PR is combined with one or two back cards, a card set is created. Table 2-2 6 provides
information about each RPM-PR card, interface, and corresponding back card.
