Preface

This preface explains the objectives, intended audience, and organization of Cisco CRS Carrier Routing System Fabric Card Chassis Installation Guide and describes the conventions that convey instructions and other information.


Note
Throughout the remainder of this installation guide, abbreviated terms are used to identify the formal names of the components that make up the multishelf system.

Objective

This installation guide describes how to install components into and remove them from an FCC. This installation guide does not provide background information and basic theory-of-operation for anyone wanting to understand the Cisco CRS Carrier Routing System.

Audience

This guide is intended for FCC installers and Cisco installation partners who are responsible for installing the FCC components. The chassis installers are expected to have installed networking hardware in the past. No additional knowledge of routing or the Cisco IOS XR software is assumed.
