Cisco CRS Carrier
Routing System Fabric Card Chassis Unpacking, Moving, and Securing Guide
. The companion document to this guide is
Carrier Routing System Multishelf System Site Planning Guide , which
describes how to plan and prepare your site facilities for the installation of
a switch fabric card chassis
The Cisco CRS Fabric
Card Chassis is part of the Cisco CRS carrier routing system multishelf system,
The CRS multishelf system consists of LCC and FCC combinations:
Chassis (commonly referred to as FCC)-the mechanical enclosure that contains
the second stage (S2) of the switch fabric in multishelf systems, system
controllers, fiber modules to interconnect to the LCC, and its own power and
The FCC supports
either 40 GB switch fabric cards (CRS-FCC-SFC), 140 GB switch fabric cards
(CRS-FCC-SFC-140), or 400 GB switch fabric cards (CRS-FCC-SFC-400). An FCC with
a mix of 40 GB,140 GB and 400 GB SFCs is not a supported mode of operation.
Such a mode is temporarily allowed only during the upgrade process.
16-Slot Line Card
Chassis (commonly referred to as LCC)-the mechanical enclosure that contains
the line cards, line card interfaces on the PLIMs, route processors (RPs) or
forwarding processors (FPs), distributed route processors (DRPs), stages one
and three of the three-stage switch fabric (S13), and its own power and cooling
document, the generic term Cisco CRS Carrier Routing system refers to the Cisco
CRS-1, Cisco CRS-3, and Cisco CRS-X Carrier Routing Systems, unless otherwise
This document provides
instructions for unpacking the Cisco CRS Fabric Card Chassis and its
components, attaching the dolly, moving the chassis safely, and securing the
chassis to the floor. This document does not provide background information and
basic theory-of-operation for anyone wanting to understand the Cisco CRS
Carrier Routing System.
This document is
intended for those who unpack the Cisco CRS Fabric Card Chassis and Cisco
installation partners who are responsible for moving and securing the LCC. No
additional knowledge of routing or the Cisco IOS XR software is assumed.
