Raised floor requirements
You can install the system on either a raised or nonraised floor.
Note: A raised floor provides both better cabling support and helps to ensure
more efficient cooling to the units.
When the system is placed on a raised floor with 60 cm

the back tile, as shown in Figure 2 and Table 11.
Note: Place the opening under the system, centered on the back edge of the tile
along the rear of the rack.
v
To allow for ventilation for airflow and support system cooling requirements,
have at least two tiles (and preferably more) in front of the system These tiles
must have a minimum of 40% perforation.
