Enclosed Equipment Cabinet
The enclosed equipment cabinet, sometime referred to as a “glass front rack,” is
basically a relay rack inside a protective metal frame. The enclosed equipment
cabinet allows networking devices to be secured as though in a relay rack, and
also prevents unauthorized access to the equipment. Keeping the cabinet door
closed and locked helps to ensure that unauthorized personnel will not be able to
modify the current organization of cables and devices.
The enclosed equipment cabinet also presents a more finished appearance, and is
often used in locations where there is no wiring closet to hide cable management
devices in. In these cases, a smoked glass front door allows LEDs and lit
indicators to be examined without having to reveal the array of cabling inside.
