Up to 15 Cisco 12000 series line cards can be installed in the routers upper and
lower card cages to support a variety of physical network media. Ports and
connectors on the line card front panels provide interfaces for external
connections. Line cards communicate with the RP and exchange packet data with
each other through the switch fabric cards.
Any unoccupied card slot in the upper and lower card cages must have a blank
filler panel installed to meet electromagnetic compatibility (EMC) requirements
and to ensure proper air flow through the chassis. Also, if the front panel of a line
card does not completely fill the card slot opening, a narrow card filler panel must
be installed to meet the EMC requirements.
A cable management bracket on the front panel of each line card helps to organize
the interface cables connected to that line card.
