5.6. Cooling Module Maintenance
5.6.1 Cooling Module Overview
♦ Redundant cooling modules: The subsystem is equipped with two (2)
redundant, dual-fan cooling modules. 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 EonStor subsystem with fans in a single PSU module for a long
period of time. If the fan in a second PSU module fails, the system is at
risk of sustaining irreparable damage.
•
Detecting a failed cooling module: If a cooling module fails, the LED
located at the back of the module, an audible alarm, the firmware, the
RAIDWatch panel view, or the Configuration Client can notify you.
•
Replacing a cooling module: Once you are notified that a cooling
module has failed, it should be replaced as soon as possible. A failed
cooling module should only be removed from the subsystem when you
have a replacement module immediately available that can be installed
as soon as the failed cooling module has been removed.
The fan replacement process should be completed within ten minutes. If
the process takes too long, the accumulated heat can damage the
subsystem.
5.6.2 Replacing a Cooling Module
If one of the cooling modules fails, it must be replaced as soon as possible.
The cooling module is secured to the PSU module with the six (6) screws
from the top. To replace the cooling module, please follow these steps:

WARNING!
WARNING!
Although the cooling modules are fully redundant, it is not
advisable to run the AR3016G with a single cooling module for an
extended period of time. If the remaining cooling module fails, the
system is at risk of sustaining irreparable damage.
Keep a failed module in its enclosure bay until a replacement unit is
in hand.
