Cooling Fan Module
The enclosure has temperature sensors in three different areas, the drive bay, the RAID
Controller, and the power supplies. There are several steps the storage system performs to
prevent component damage due to over temperature conditions.
If the drive bay area reaches a temperature of 50°C (122°F) an audible alarm will sound, the
front panel Fan Status LED will flash alternately amber then green, and the monitoring
software will post a warning message. These events are interpreted by SAF-TE and report in
the form of notifications which give the user a warning that a condition is causing the
enclosure temperature to exceed the preset maximum allowable value, and an action is
required by the user to determine the cause and take corrective measures. It may be due to a
blockage of air flow or a low fan speed.
If the RAID Controller reaches a temperature of 65°C (149°F) an audible alarm will sound,
the front panel Fan Status LED will flash alternately amber and green, and the monitoring
software will post a warning message. If the temperature on any RAID Controller continues
to rise and reaches 71°C (159°F) the controller will flush its cache and shutdown. The
controller will also spin down the disk drives at this temperature.
If a power supply reaches 85°C (185°F), it will shut down.
