System Cooling
When many pieces of equipment are mounted in an equipment rack, a considerable
amount of heat may be produced, which must be removed efficiently. Further, a lower operating
temperature will make equipment operate more reliably, and it will last longer. In the extreme
case, excessive temperatures cause rapid equipment failure, and damage which can be difficult to
repair.
Heat in an equipment rack should be removed by forced air. This is often accomplished by
blowers installed in the top of the rack, venting into the room. An alternative is to draw hot air
from the top of the rack into an air-conditioning return duct, and not vent it into the equipment
room; cold air should be ducted into the bottom of the rack.
The optimum air temperature for cooling electronic equipment is 25° C (72° F). When
many pieces of equipment are contributing to the heat load, a substantial air-flow will be needed,
and the inlet temperature may need to be lower.
Check These Points
•
Are all ventilation holes in the Image Server free of obstruction?
•
Can blowers or HVAC system adequately remove heat from the equipment rack?
•
Have you measured the actual temperature inside the rack? Do this near the top.
•
Verify that the HVAC system is not on a timer that can shut off on weekends or holidays.
•
What procedures are in place to protect the equipment when the HVAC system fails?
