Requirements
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
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 router 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).
