Cooling Module Overview

•

Redundant cooling modules: The RAID subsystem is equipped with redundant, hot-swap- pable, single-fan cooling modules. Two are located below the PSU modules. The third is located below the controller module. These cooling modules control the internal opera- tional temperature of the subsystem and therefore their working integrity should be maintained at all times.

Detecting a failed cooling fan 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 firm- ware, the RAIDWatch Panel View, or 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.

i

NOTICE!

The latches at the back of the cooling module secure the cooling fan module into the enclo- sure. If these latches are broken, the warranty on the cooling fan module will be void.

6.6.2Replacing a Cooling Module

CAUTION!

Although the cooling fan modules are fully redundant, it is not advisable to run the RAID sub- system with one or two cooling modules for an extended period of time. Whenever a cooling module fails, the system is at risk of sustaining irreparable damage.
