The minimum amount of clearance space for the front and rear of the VAX
6000 is 1 meter (39 inches) as shown in Figure 1–1.
Air is taken in through the front and rear doors by the two blowers located
in the lower half of the cabinet. The air is circulated up through the card
cages and power regulators as shown in Figure 1–2. If there are in-cabinet
devices such as disk drives, air enters through the bottom grill.
If you are installing a system on a raised floor, ensure that a proper airflow
path is provided. If the floor has perforated tiles, position one or two tiles
in areas where air will enter the cabinet. If the floor has aluminum grills,
position two grills under the area where air enters the cabinet.
