Notes on Cooling Module Maintenance

˙
Redundant cooling modules: The subsystem is equipped
with cooling fans, one (1) within each cooling module. There
are three (3) cooling modules in total. 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 a fan in a single
PSU module for an extended period of time. If the cooling fan in
the only remaining module fails, the subsystem will quickly
overheat.
˙
Detecting a failed cooling module: If a cooling module fails,
the LED located at the rear-facing faceplate, an audible alarm,
the embedded firmware utility, and the SANWatch software
suite can notify you.
˙
Immediate replacement: Once you are notified that a cooling
module has failed, it should be replaced as soon as possible. A
failed module should only be removed from the subsystem
when you have a replacement immediately available.
5-12
saddle notches on the sides of the handle can snap onto
the metal protrusions along the interior walls of the PSU
bay. Push the PSU into chassis. When you feel the
contact resistance, use slightly more force to engage the
back-end connectors. Push the handle upwards to
secure the module.
Secure the PSU to the subsystem by fastening the
retention screw through the PSU extraction handle.
Install the cooling module into the lower level of the
replacement PSU canister. Please refer to Section 5.6.2,
Step 3.
Replace the power cord that connects the PSU to the
main power source.
Power on the PSU by flipping its power switch.
Ensure the replacement PSU is working properly by
checking its LED. The LED should light constant green
when the PSU is powered on.
