Cooling Fan Module
The cooling system consists of two high-performance (80-CFM) cooling fans
mounted in a single fan module which slides into a bay at the rear of the
enclosure. The design of the fan module provides for an easy-to-install user-
replaceable component in a live environment without interruption of service.
If any one fan should fail, cooling redundancy and efficiency are degraded. The
cooling fans and enclosure temperature are constantly monitored by the SES
processor for fault conditions. In the event of a fault condition the front panel Fan
Status LED will change from a green state to a solid amber state in the case of a fan
failure, or to a blinking amber green state in the case of an over-temperature
condition. In both cases an audible alarm sounds. The SES processor will also
provide notification data to monitoring software, such as StorView.
WARNING:
Do not operate the enclosure for extended periods of time (greater
than 5 minutes) with the cooling fan module removed.
The enclosure has temperature sensors in three different areas, the drive bay, the
RAID controllers, and the power supplies. There are several steps the storage
system performs to prevent component damage due to over temperature
conditions.
