Dust on devices may cause electrostatic discharge and result in poor contact for connectors or
metal connection points. This problem can shorten the life span of devices and cause faults.

Requirements
The door of the equipment room should be 2 m (6.56 ft) high and 1 m
(3.28 ft) wide. One door is enough. Seal the doors and windows with
dustproof plastic tape. Use double-pane glass in the windows and seal
them tightly.
Paste wallpaper on the wall or apply flat paint. Do not use pulverized
paint.
Use cable trays to arrange cables. The inner faces of the cable trays must
be smooth. The reserved length and width of the cable trays, and the
number, position and dimensions of the holes must comply with the
requirements of device arrangement.
Do not pass service pipes, drainpipes, and storm sewers through the
equipment room. Do not place a fire hydrant in the equipment room, but
place it in the corridor or near the staircase.
Separate the area where the equipment is installed from the equipment
room door. The partition wall can block some outside dust.
Install air conditioner vents so that the air does not blow directly on
equipment.
Avoid the proliferation of mildew, and keep out rodents (like mice).
