CHAPTER 2 Installation Sites
d) Newly constructed buildings
If a server system is to be installed in a newly constructed building, it is
recommended that loading strength of the floor itself, beam, and column is 4.9 kN/

m (100 lbf/ft
(2) Vibration and earthquake-proofing
Recent years have witnessed the emergence of earthquake-free buildings mounted on
earthquake-free foundations that absorb the effects of earthquakes and computer
rooms with earthquake-free floors as safeguards against earthquakes. Because the
higher floors in an ordinary building are more susceptible to the effects of earthquakes
than the lower floors, it is recommended that server systems be installed on lower
floors.
Regarding the floor on which the server system is to be setup, special consideration
should be given to the following:
 As little vibration as possible in the steady state
 Vibrations during earthquakes not exceeding 2.5m/S
 If vibrations during earthquakes exceed 2.5m/S
safeguards against earthquakes. The safeguards against earthquakes include
earthquake-free method, securing method, or clamping devices in position.
(3) Water damage
a) Drainage
The basement or the first floor of a building should be avoided as a site for installing
a server system because these floors can be flooded during floods. If installing a
server system on such floors is unavoidable, embankments or drainage facilities
should be provided to ensure uninterrupted functionality of the server system.
b) Structure
The building in which a server system is installed must be so structured to protect
the server system from the effects of the following:
 Damage from storms and flooding
 Fire fighting water
 Water leaking from the roof
 Water flowing from stairways
 Water leaking from water facilities in the upper floor(s)
 Water leaking from the water pipelines above the ceiling
