There may be up to four fansin each power supply/fan module. This configuration provides N+1 fan redundancy, meaning that theenclosure can be sufficiently cooled for normal operation even if one fan fails.Firmware shall continuously monitor the temperature sensors within the enclosure and take properactions to throttle the fans in order to maintain optimal operating temperature.Over-Temperature ShutdownIn order to prevent potential damage to the drives and subsequent loss of data, the power supply hasthe capability to shut itself down or be shut down by the RAID controller in the event of an over-temperature condition. When the power supply incorporates its internal thermal shutdown feature, itwill automatically restart when the over temperature condition no longer exists. Hysteresis of at least5 degrees is employed to prevent a frequent toggling on and off of the outputs.
