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 eases cable maintenance, reduces potential

communication faults, and maximizes efficiency.

Construction Requirements for the Equipment Room

Table 5-10 shows 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.
