5.6. Replacing a Failed Cooling Module

5.6.1 Notes on Cooling Module Maintenance

♦ Two redundant cooling modules: The subsystem is equipped with two (2, GHDX-

2422S-8F4D) or three (3, GHDX-2422S-12F4D)redundant, hot-swappable, single-

fan cooling modules located in the lower PSU module slot. These cooling modules

control the internal operational temperature of the subsystem and therefore their

working integrity should be maintained at all times.

♦ Detecting a failed cooling module: If a cooling module fails, you can be notified of

the failure by the LED located at the back of the module, an audible alarm, the

firmware screen, the RAIDWatch Panel View, or through the various methods by the

Configuration Client utility.

♦ Replacing a cooling module: When 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 that can be

installed as soon as the failed cooling module has been removed.

WARNING!

• The latches at the back of the cooling module secure the cooling module into the

enclosure. If these latches are broken, the warranty on the cooling module will

be void.

• Although the cooling modules are fully redundant, it is not advisable to run the

Galaxy subsystems with any of the cooling modules missing. Whenever a 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.

5.6.2 Replacing a Cooling Module

The cooling modules are secured to the chassis with two black latches located on the rear

of the module. To replace the cooling module, please follow these steps:

Step 1. Remove the cooling module. Squeeze both side latches towards the

center of the cooling module and gently withdraw the cooling module

from the subsystem by gently pulling on the silver handle at the

bottom. (See Figure 5-10)
