The general layout principles of the equipment room are as follows:

l It should meet requirements for laying out and maintaining communication cables and

power cables.

l It should reduce the cabling distance, which facilitates cable maintenance, reduces

potential communication faults, and maximizes efficiency.

Construction Requirements for the Equipment Room

Table 5-10 describes the construction requirements for the equipment room.

Table 5-10 Construction requirements for the equipment room

Item

Requirements

Area The smallest area of the equipment room can accommodate the

equipment with the largest capacity.

Net height The minimum height of the equipment room should not be less than 3 m

(9.84 ft). The minimum height of the equipment room is the net height

below overhead beams or ventilation pipes.

Floor The floor in the equipment room should be semi-conductive and

dustproof. A raised floor with an ESD covering is recommended. Cover

the raised floor tightly and solidly. The horizontal tolerance of each

square meter should be less than 2 mm (0.08 in.). If raised floors are

unavailable, use a static-electricity-conductive floor material, with a

volume resistivity of 1.0 x 107 ohms to 1.0 x 1010 ohms. Ground this

floor material or raised floor. You can connect them to ground using a

one megohm current-limiting resistor and connection line.

Load-bearing

capacity

The floor must bear loads larger than 150 kg/m

(0.21 bf/in.
