Transferring RP and Line Cards
You must remove the line cards and RP(s) from the RP and line card cage, then install them in the card
cage in the replacement chassis. To maintain proper air flow and for EMI performance, card slot blanks
must be installed in slots without cards. RP and line card captive screws must be tightened on the
replacement chassis to ensure electromagnetic compliance (EMC).
Caution One edge of the card carrier faceplate is lined with an EMI-preventive gasket consisting of many raised,
conductive contacts. Be careful not to damage the gasket contacts, because a damaged card carrier gasket
can reduce EMI performance.
Cisco 12000 Series line cards are OIR (hot-swappable) FRUs. RPs also support OIR, but are
hot-swappable only when the system is equipped with two RPs.
To remove an RP or line card from the RP and line card cage, see
