Line Cards

Line Cards

Cisco 12006 and Cisco 12406 routers come pre-installed with the number and type of line cards that you ordered. Line cards and RPs can be installed in two basic combinations to support RP redundancy and a variety of physical network media:

•Nonredundant RP—One RP and up to five Cisco 12000 Series Router line cards.

•Redundant RPs—Two RPs and up to four Cisco 12000 Series Router line cards.

Line cards can be installed in any slot—zero (0) through five (5)—in the card cage. Slot number 5 is the recommended default RP slot. Single-mode and multimode line cards are shown in Figure 1-10.

Line cards provide the interfaces to the router’s external physical media. External connections are made from the front of the chassis to the connectors on the line card face plates. The line cards communicate with the RP and exchange packet data with each other through the switch fabric cards in the switch fabric and alarm card cage.

Caution Any unoccupied card slot in the line card and RP card cage must have a blank filler panel installed for electromagnetic compatibility (EMC) and to ensure proper air flow through the chassis. When the faceplate of a line card does not completely fill the card slot opening, a narrow card filler panel must be installed.

A cable-management bracket attaches to the faceplate of each line card to manage and organize the network interface cables connected to the individual ports on the line card.

Line cards installed in the router support online insertion and removal (OIR), which means you can remove and replace a line card while the router remains powered up.

Note For detailed instructions on removing, replacing, and configuring the line cards, see the configuration note shipped with each line card when ordered as an FRU.
