Cisco XR 12404 Router Overview

This chapter provides an overview of the Cisco XR 12404 router. It contains
physical descriptions of the router hardware and major components, and
functional descriptions of hardware-related features.

Router Overview

The Cisco XR 12404 router scales the Internet Service Provider edge from speeds
of T3/E3 (44.7/34.4 Mbps) up to OC-192/STM-64 or 10GE (10 Gbps).

Figure 1-1

shows the PRP-2, consolidated switch fabric (CSF) card, and line card

locations of the Cisco XR 12404 router. Network interfaces reside on the line
cards that provide the connection between the router’s CSF and the external
networks. The bottom slot (labeled Fabric Alarm) is a dedicated slot for the
combined CSF card.
