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 “Rack Specifications and
Recommendations” on page 36 for information.
● 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
Extreme Networks recommends that you consult an electrical contractor for commercial building and wiring
specifications.
Electrostatic Discharge
Your system must be protected from static electricity or electrostatic discharge (ESD). Take the following
measures to ensure optimum system performance:
● Remove materials that can cause electrostatic generation (such as synthetic resins) from the wiring
closet. Check the appropriateness of floor mats and flooring.
● Connect metal chassis, conduit, and other metals to ground using dedicated grounding lines.
● Use electrostatically safe equipment and the ESD-preventive wrist strap that is provided with your
equipment. All BlackDiamond switches have ESD-preventive wrist strap connectors and are shipped
with an ESD-preventive wrist strap.
Humidity
To maximize equipment life, keep operating humidity between 50% and 70% relative humidity
(non-condensing) during typical operation. The equipment can operate between 10% and 95% relative
humidity (non-condensing) for short intervals.
