Installation Guide

To run your equipment safely, you must meet the specific power requirements for each switch and
external power supply unit installed in the system.
For power specifications of the switches, see the specific switch listings in Technical Specifications
on page 315.
Operating Environment Requirements
Verify that your site meets all environmental and safety requirements.
Virtually all areas of the United States are regulated by building codes and standards. During the early
planning stages of installing or modifying your network, it is important that you develop a thorough
understanding of the regulations that pertain to your location and industry.
