Document Objectives

This publication contains the initial site preparation, installation, configuration, troubleshooting, and selected upgrade and maintenance procedures for the Cisco DistributedDirector 2500 Series (also called "the Director" in this publication).


This publication is for the Director installer, who should be familiar with electronic circuitry and wiring practices and have experience as an electronic or electromechanical technician. The Director documentation is intended primarily for users who configure and maintain the Director, but are not necessarily familiar with tasks, the relationship between tasks, or the commands necessary to perform particular tasks. Familiarity with the concepts and functionality of Domain Name System (DNS) servers is assumed.
