Wiring Closet Considerations
Be aware of the following recommendations for your wiring closet:
Be sure that your system is easily accessible for installation and service. See
●
Recommendations" on page 70
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 distribution 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
Extreme Networks recommends that you consult an electrical contractor for commercial building and wiring
specifications.
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.
Follow these general thermal recommendations for your wiring closet:
Be sure that the ventilation in the wiring closet is adequate to maintain a temperature below 104° F
●
(40° C).
Install a reliable air conditioning and ventilation system.
●
Keep the ventilation in the wiring closet running during non-business hours; otherwise, the
●
equipment can overheat.
Maintain an ambient operating temperature of 32° to 104° F (0° to 40° C).
●
Maintain a storage temperature of -40° to 158° F (-40° to 70° C).
●
NOTE
As with all electrical equipment, Extreme Networks product lifetimes degrade with increased temperature. If
possible, temperatures should be kept at approximately 78° F (25° C) or lower.
