MGX 8950 Card Sets

Note Cisco Systems recommends you use all four XM-60 modules for full redundancy.

A card set consists of a front card with its attached daughter card and one or two back cards (or line cards). The front card contains the processing intelligence and, on the daughter card, the firmware that distinguishes the interface (OC-48, OC-12, OC-3, T3, E3, and so on). The back cards on the AXSM simply provide the electrical or optical interface for one or more lines of a particular type. See Table 2-1for a list of front and back cards.

Note The daughter card is not a field-replaceable module, so this manual does not describe it.
