Notes on Cooling Module Maintenance
Redundant cooling modules:
The subsystem is equipped
with four (4) cooling blowers, two (2) within each cooling
module. These cooling modules control the operating
temperature within the chassis 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 EonStor 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.
