Chapter 2: Installation

Figure 2-1. Recommended installation.

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.

Once the cabinet is removed from the shipping skid, roll it into position on the casters that 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 Cold Row 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 flat-head screwdriver to turn the screws, located at the top of the four caster housings (accessed inside the front and rear corners of the cabinet per Figure 1-2). Raise or lower each foot until the cabinet is level and even with the adjacent equipment racks (see Figure 2-1).

2.5 Air Distribution

Air from the hot aisle is drawn into the rear of the Cold Row cabinet and passes through the fins of the cooling coil. The conditioned supply air discharges through the front of the cabinet (see Figure 2-2).
