44 Extreme Networks Consolidated Hardware Guide

Site Preparation

• Use appropriate DC power for your switch, as described in Table 16.

• Use a vinyl floor covering in your wiring closet. (Concrete floors accumulate dust, and carpets can

cause static electricity.)

• Prevent unauthorized access to wiring closets by providing door locks. Install the equipment in a

secured, enclosed, and restricted-access area, ensuring that only qualified service personnel have

access to the equipment.

• Provide adequate overhead lighting for easy maintenance.

• Ensure that each wiring closet has a suitable ground. All distribution racks and equipment installed

in the closet should be grounded.

• Ensure that all system environmental requirements are met, such as ambient temperature and

humidity.

NOTE

Extreme Networks recommends that you consult an electrical contractor for commercial building and

wiring specifications.
