maintenance and management, place the equipment in different rooms. Figure 9-79 shows the
layout of the equipment room.

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.
9.3.1.3 Construction Requirements for the Equipment Room
Table 9-15 describes the 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.
