Preface

This document describes how to plan and prepare your site facilities for the installation of a Cisco Carrier Routing System 8-Slot Line Card Chassis (also referred to in this document as the Cisco CRS 8-slot LCC). The guide provides a brief description of the chassis, its components, and basic site facilities requirements.

The guide describes the power, cooling, and environmental specifications to consider before ordering and installing the chassis. It also describes each chassis, its components, site facilities requirements (such as floor space, weight requirements, receiving, and staging), and installation to help you plan the site where the system will be installed. The Cisco product IDs (PIDs) are listed in System Product IDs chapter.


Note

The installation of a Cisco CRS 8-slot LCC may require space, floor loading, power, and cooling modifications to a facility. Therefore, you should plan the site well in advance of the delivery of the system.

Audience

This document is intended for those who must plan the facilities for the site where Cisco CRS 8-slot LCC is to be installed. It should be used with Cisco site planning coordinators and site inspections, well in advance of the delivery of the system.
