This guide is written for network administrators and technicians responsible for
hardware installation.
Chapter Organization
The contents of this guide are organized as follows:
Chapter 1 Provides an overview of the repeater and describes the repeater's
features and components.
Chapter 2 Helps you plan the installation of the repeater. It includes all
repeater installation requirements as well as charts for planning the repeater
setup and rack inventory.
Chapter 3 Provides instructions for installing the repeater, installing a
Smart Uplink Module (SUM), interconnecting repeaters, and powering up the
repeater.
Chapter 4 Provides information about in-band and out-of-band repeater
management, including SNMP, RMON, Telnet, and the VT100 console
interface.
Appendix A Includes the repeater's physical, electrical, and environmental
specifications.
