SECTION 6—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 growrth. 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 seven 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.
