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.
