There are five fans in the fan tray. If an individual fan fails, the other fans continue
to run. Sensors monitor the internal air temperatures. The number of fans in
operation and their speed varies according to the internal temperature for the
quietest operation possible. If the air temperature exceeds a desired threshold, the
environmental monitor displays warning messages.
