Chapter 1: About the Gateway 850 SCSI Storage Enclosure
Cooling fan module
The cooling system consists of two high-performance (80-CFM) cooling fans
mounted in a single fan module which slides into an open bay at the rear of
the enclosure. The design of the fan module provides an easy user-replaceable
component in a live environment without interruption of service.
If any one fan should fail, cooling redundancy and efficiency are degraded. If
a fan fails, the SAF-TE processor communicates status of the cooling fans, which
turns on the Fan Status LED and an alarm. The SAF-TE processor will also
provide the notification data to any monitoring software.
The enclosure temperature sensors are monitored for out-of-tolerance
conditions of the established temperature threshold value of 60°C (140°F). If
a threshold value is exceeded, the Fan Status LED will begin flashing orange.
Warning
The fan module can be replaced during normal operation without turning off
the enclosure or interrupting normal system operations.
8
Do not operate the enclosure for extended periods of time
(greater than 5 minutes) with the cooling fan module
removed. No enclosure cooling is available while the fans
are removed.
