Physical and Functional Description of Router
The Cisco XR 12404 router supports up to 8 chassis in a one standard 7-foot

• Line cards—The card cage contains 4 hot-swappable card slots. The router
can accommodate up to three OC-192 line cards (or 2 line cards if redundant
route processors are installed). See the “Supported Line Cards” section on
page 1-13 for information.
• Consolidated switch fabric card (CSF)—Switch fabric, alarm, and clock
schedule functions are located on one board. The CSF card has a switching
capacity of 10 Gbps. See the “Consolidated Switch Fabric Card” section on
