5.6 Cooling Module Maintenance
5.6.1 Cooling Module Overview
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 Galaxy subsystem with fans in a single PSU module for a long
period of time. If the fans 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 LEDs
located at the back of the PSU module, an audible alarm, the firmware,
the RAIDWatch manager software, 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.
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!
The fan replacement process should be completed within ten 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.
Step 2.
Use a medium-size Phillips screwdriver to remove the six screws
from the top of the PSU module.
