Chassis Overview

This chapter provides an overview of the Cisco CRS Carrier Routing System 8-Slot Line Card Chassis
Enhanced router and the basic system configuration. It contains the following topics:

Overview

The Cisco CRS 8-slot Line Card Chassis Enhanced router supports 40 G, 140 G, and 400 G fabric cards and
line cards. The Cisco CRS 8-Slot Line Card Chassis Enhanced router consists of one of the following:
• A single, 8-slot, 40-Gbps-per-slot line-card shelf for a total switching capacity of 640 Gbps
• A single, 8-slot, 140-Gbps-per-slot line-card shelf for a total switching capacity of 2.24 Tbps
• A single, 8-slot, 400-Gbps-per-slot line-card shelf for a total switching capacity of 12.8 Tbps
The 8-slot chassis is a half-height, rack-mounted 8-slot version of the Cisco CRS 16-Slot Line Card Chassis
Enhanced router.
The routing systems are built around a scalable, distributed three-stage switch fabric and a variety of line card
(packet) interfaces. These packet interfaces are located on modular services cards (MSCs), forwarding
processors (FP), or label switch processor (LSP) cards and their associated physical layer interface modules
(PLIMs) which can be referred to as line cards and are effectively cross-connected to each other through the
switch fabric. MSC, FP, and LSP cards are also referred to as line cards.
The routing system consists of a single, rack-mounted Cisco CRS 8-Slot Line Card Chassis Enhanced router
that contains the system components:
• Up to eight MSC, FP, or LSP line cards.
• Up to eight physical layer interface modules or PLIMs (one for each line card).
• Route processor (RP) cards (up to two) or performance route processor (PRP) cards (up to two)
• Switch fabric cards (four required)
