Document Organization

This cabling guide contains the following chapters and appendixes:

Chapter 1 "Introduction to Multishelf System Cabling," provides a brief overview of interconnection cabling requirements for the Cisco CRS Multishelf System.

Chapter 2 "Cabling for System Management, Alarms, and Network Clocking," provides information about how to provide cabling for basic system management.

Chapter 3 "Cabling the Control Network Using 22-Port Shelf Controller Gigabit Ethernet Cards," describes how to attach data and optical cables between the 22-port shelf controller Gigabit Ethernet cards, two line card chassis, and one or more fabric card chassis.


Note The multishelf system control network is configured with 22-port shelf controller Gigabit Ethernet (22-port SCGE) cards. Follow the steps in the chapter that applies to your configuration.


Chapter 4 "Cabling the Fabric," describes how to interconnect the switch fabric cards between two line card chassis and one, two, or four fabric card chassis.

"Multimodule Horizontal Cabling Plans" describes cabling plans that you might use for expanded Cisco CRS Multishelf installation.

"Vertical Cabling Plans" shows the multimodule fabric cabling connection plan for eight planes in a 9+1 multishelf installation.

Document Conventions
