It should reduce the cabling distance, which facilitates cable maintenance, reduces
potential communication faults, and maximizes efficiency.
describes the construction requirements for the equipment room.
Requirements
The smallest area of the equipment room can accommodate the
equipment with the largest capacity.
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.
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.
The floor must bear loads larger than 150 kg/m
