Characteristic
Description
Cooling System
Positive pressurization forced air circulation system utilizing a single low-noise squirrel cage
centripetal blower configuration with no removable filters.
Blower Speed Control
Rear panel switch selects between full speed and variable speed. Slot exhaust temperature and
ambient air temperature are monitored so that a constant delta temperature is maintained
across the module with the highest exit air temperature at the minimum operational blower
speed.
Slot Activation
Installing a module activates the cooling for the corresponding occupied slots by opening the air flow
shutter mechanism.
