Figure 2.2 Floor Panels With An Airflow Control Damper; Figure 2.3 Air Flow Control Panel - Fujitsu M10 Series Installation Planning Manual

The number of floor panels with an airflow control damper or number of airflow
control panels required should be determined by the air conditioning facility or the
free-access floor construction designer on the basis of the concerned heat load in the
room.

b) When underfloor ventilation and room air conditioning are combined
When underfloor ventilation is used to cool the equipment, with room air
conditioning available to air condition the building in which the server system is
housed, floor panels for the building's air conditioning system are not required.
(5) Slopes and stairways
If there is a difference in levels between the base floor and the free-access floor, either
a slope or stairway must be built at the entrance of the computer room to facilitate
traffic or physical transportation.
