This preface explains the objectives, intended audience, and organization of this Cisco CRS-1 Carrier Routing System 16-Slot Line Card Chassis Site Planning Guide, referred to in this document as the site planning guide, and describes the conventions used in the document.

Objective

This guide describes the basic facilities requirements, such as floor space, power requirements, environmental requirements, and so on, for the Cisco CRS-1 16-slot line card chassis. The guide is intended to help you plan the sites where the chassis will be installed. It should be used with
Cisco Systems site planning coordinators and site inspectors, well in advance of the delivery of the chassis.

Audience

This guide is intended for anyone who plans the facilities, including space, floor weighting, power, cooling, cabling, delivery, and storage, for the installation of a Cisco CRS-1 16-slot line card chassis.

Document Organization

This guide contains the following chapters and appendixes:

•Chapter 1, "Cisco CRS-1 Carrier Routing System," describes the Cisco CRS-1 routing system and presents an overview of the steps required to prepare the site for the installation of a line card chassis.

•Chapter 2, "Space Planning," provides information about chassis space requirements and other site preparation details (for example, floor loading and securing the chassis to the floor).

•Chapter 3, "Power and Cooling Requirements," describes the power and cooling requirements for the chassis.

•Chapter 4, "Shipping and Receiving," describes the things to consider as you plan for the shipment of the chassis and transport to the installation site.

•Chapter 5, "System Planning Considerations," provides information about system planning considerations, such as high availability.

•Appendix A, "Product IDs," provides the product identifiers (IDs) for orderable chassis components.

•Appendix B, "Preliminary Site Survey," contains a sample preliminary site survey in which you can enter information about the installation site and site-preparation process.

•Appendix C, "System Specifications," lists the chassis specifications and provides information about wire gauges and resistances for DC power cabling.
