What's Illumination Requirements

5

The TR should be equipped with the following illumination systems:

Active illumination system, which is powered by the mains supply.

Backup illumination system, which is powered by the backup power supply (such as the diesel electric generator) in an office.

Emergency illumination system, which is powered by storage batteries when the mains supply has been interrupted but the backup power supply has not yet started to supply power.

What's Construction Requirements
Area The TR should be able to house all the planned equipment. Indoor height The indoor height indicates the distance between the floor and the beam or ventilation pipe of the TR. The height cannot be less than 3 meters. Floor It is recommended that the TR also have a movable raised floor properly. The horizontal tolerance in each square meter must be less than 2 meters. If a movable raised floor is not available, static electricity conductive floor materials with the volume resistivity of 1.0 x 107 ohms to 1.0 x 1010 ohms should be used instead. The static electricity conductive floor materials or the movable raised floor must be connected to a ground point through a current limiting resistor and a connection line. The resistance of the current limiting resistor should be 1 megohm. Load-bearing capacity The load-bearing capacity should be greater than 450 kg/m2. Doors and windows The doors and windows must be sealed with dust-proof plastic tapes. It is recommended that windows be constructed with double-layer glass and be sealed properly. Wall surface The walls can be pasted with wallpapers or daubed with flat paint. Note that the paint that can be easily pulverized must not be used. Water pipe It is recommended that water supply pipes, drainpipes, and storm sewers should not be routed across the TR. Fire hydrants must be installed in a corridor or near a staircase where convenient access is possible. Internal partition wall The area where the server is installed should be isolated from the door of the TR by an internal partition wall, because an internal partition wall can prevent dust from entering. Installation position of air conditioners Air conditioners should be installed in a proper position where the air does not blow directly at the server. Other requirements Measures should be taken to prevent micro-organisms such as fungi and molds and rodents such as rats from entering the TR.
