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 141 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.
