Set Up the Wiring Closet
Be aware of the following recommendations for your wiring closet:
•
Make sure that your system is easily accessible for installation and service. See
and Recommendations
•
Use appropriate AC or DC power, power distribution, and grounding for your specific installation.
•
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 location, ensuring that only qualified service personnel have
access to the equipment.
•
Provide adequate overhead lighting for easy maintenance.
•
Be sure that each wiring closet has a suitable ground. All equipment racks and equipment installed
in the closet should be grounded.
•
Be sure that all system environmental requirements are met, such as ambient temperature and
humidity.
Note
Consult an electrical contractor for commercial building and wiring specifications.
Control the Temperature
Extreme Networks equipment generates a significant amount of heat. It is essential that you provide a
temperature-controlled environment for both performance and safety.
Install the equipment only in a temperature- and humidity-controlled indoor area that is free of airborne
materials that can conduct electricity. Too much humidity can cause a fire. Too little humidity can
produce electrical shock and fire.
