3.5.1 Floor Space Requirements
The equipment room floor space must meet the needs of:
Future capacity expansion
Feeder window installation and feeder routing inside the equipment room
Easy installation and maintenance
Opening and closing of cabinet doors
3.5.2 Height Requirements
The desired height of the equipment room, that is, the distance from the beam or the
ventilation pipe to the floor, shall be no less than 3 m. This makes it easy to install the
cabling rack and route cables and feeder pipes.
3.5.3 Load Bearing Requirements
The load bearing capability of the equipment room depends on:
Equipment weight
Equipment floor space
Selected installation position
Equipment room structure
Ask an architectural engineer to verify the bearing capacity of the equipment room. If
the capacity fails to satisfy the need, reinforce the building.
3.5.4 Floor Requirements
An antistatic floor inside the equipment room must meet the following needs:
The resistance of an antistatic raised floor must comply with the specifications for
those in computer equipment rooms.
The floor is firm and tight, with a horizontal error no greater than 2 mm.
If antistatic raised floor is not available, you can use a static-conductive floor with
volume resistivity from 1.0 × 10
Be sure to connect the floor to the grounding device through a current-limiting
resistor and connecting cables. The resistance of the resistor shall be 1 MΩ.
Tests show that a terrazzo floor or cement floor can reach this standard.
Be sure to cover all the cabling holes on the floor with cover plates. Make sure
the holes are accurate in position and size for future installation ease.
