Cisco CRS Carrier Routing System 8-Slot Line Card Chassis Site Planning Guide



This site planning guide describes how to plan and prepare your site facilities for the installation of a
Cisco CRS 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 and its components, and
basic site facilities requirements.

This guide describes all power, cooling, and environmental specifications to consider before ordering
and installing the Cisco CRS 8-slot LCC. This guide also describes site facilities requirements, such as
floor space, weight requirements, receiving and staging, and installation information to help you plan
the site where the routing system will be installed.


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 scheduled delivery
of the system.


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