ENVIRONMENTAL REQUIREMENTS

This section provides information on floor and wall space requirements for System 25

cabinets and associated peripheral equipment.

Also included are specifications for

temperature,

humidity, air purity, lighting,

electrical noise (RFI) suppression, power,

grounding, and lightning protection.

Floor Plans And Layouts

Floor plan arrangements will vary depending on the available equipment area and anticipated

system growth. A typical floor plan is shown in Figure 6-1.

The floor must be tiled or suitably sealed, level, and free from vibration. Allow for a minimum

unobstructed clearance of 7 feet above the floor throughout the equipment area.

Do not locate the equipment in areas:

● Where it might be subjected to excessive vibrations or disturbed by moving

equipment such as hand trucks and transporters.

● Where noise levels may exceed 90 dB.

● Susceptible to flooding.

Maintain clear access to the equipment area for both installation and maintenance purposes.

The wall behind the system cabinet must be clear of all objects (pictures, shelves, or

windows) that might interfere with system installation.

The entire area behind the cabinet

and to the side as shown on Figure 6-2 must be reserved for the cross-connect field and

cable access. Also, room for system growth should be considered.
