5.6.1 Notes on Cooling Module Maintenance
Redundant cooling modules:
The subsystem is equipped with four
(4) cooling fans, two (2) within each cooling module. These
cooling modules control the internal operating temperature of the
subsystem and therefore their working integrity should be
maintained at all times.
Although the cooling modules are fully redundant, it is not
advisable to run the Galaxy subsystem with fans in a single PSU
module for an extended period of time. If the cooling fans in the
only remaining module fail, the subsystem will quickly overheat.
Detecting a failed cooling module:
If a cooling module fails, the
LEDs located at the rear-facing faceplate of the PSU module, an
audible alarm, the firmware utility, the RAIDWatch manager
software, or the Configuration Client utility can notify you.
