Notes on Cooling Module Maintenance
Redundant cooling modules
: The subsystem is equipped with
four (4) cooling fans, two (2) within each PSU 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 EonStor subsystem with fans in a single PSU
module for an extended period of time. If the cooling fans in the
only remaining PSU module fail, the subsystem will quickly
overheat.
Detecting a failed cooling module:
If a cooling module fails, the
LEDs located at the back of the PSU module, an audible alarm, the
firmware, the RAIDWatch manager software, or the Configuration
Client software 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.
5.7.2
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, follow the steps
below:
WARNING!
The fan replacement process should be completed within five (5)
minutes. If the process takes too long, the accumulated heat can damage
the subsystem.
Step 1.
To remove the cooling module,
remove the PSU
module first. Please follow the PSU removal process
listed in the previous discussion.
