NOTE
Placement of air barriers between the cold aisle/
hot aisle is important. If the supply discharge
is too close to the hot aisle, the conditioned
supply air will be recirculated back to the intake
in the hot aisle side of the cabinet before it has
circulated through the equipment to be cooled.
An air barrier may also be provided to prevent
conditioned air from being drawn over the top of the
row into the hot aisle (See Figure 3).

Once the cabinet is removed from the shipping skid,
it may be rolled into position on the casters which are
mounted to the bottom of the unit. Do not remove
the shipping support brackets unless server racks are
installed on each side of the CyberRow cabinet.
The cabinet is equipped with an adjustable foot at each
corner to raise the cabinet off the casters after the unit is
positioned in its operating location. The adjustable feet
are also used for leveling and overall height correction.
To adjust the height, use a fl at head screwdriver to
turn the screws, located at the top of the four caster
housings (accessed inside the front & rear corners of
the cabinet per Figures 1 and 2), to raise or lower each
foot until the cabinet is level and even with the adjacent
equipment racks (see Figure 3).
2.5 Air Distribution
Air from the hot aisle is drawn into the rear of the
CyberRow cabinet and passes through the fi ns of the
cooling coil. The conditioned supply air discharges
through the front of the cabinet (see Figure 4a).

Figure 4a- Typical Air Distribution
The front discharge panel directs the supply air out of the
CyberRow unit where it will be drawn into the front of
the server racks.
An optional front diverted air discharge panel is also
available. This directs the supply air sideways out of the
CyberRow unit and directly into the front of the server
racks (see Figure 4b).
