Product Overview

The heart of the Cisco 12404 Internet Router is the consolidated switch fabric
(CSF) card circuity, which provides synchronized interconnections for the line
cards and the route processor (RP). The CSF card also contains alarm functions
to alert you to conditions in the router through LEDs.
This Cisco 12404 Internet router overview is presented in the following sections.
The 12404 series routers described in this guide are:
The original Cisco 12404 Internet router.
