Fig. 6.9 Remove the Cooling Module

6. Reinstall the cooling module into the new PSU module. To do this, align the cooling mod-

ule with the lower level of the PSU bracket and gently slide the cooling module in.

7. Reinstall the PSU module. After the cooling module has been reinstalled, align the PSU

module with the empty bay from which the faulty module was removed. Gently slide the

replacement PSU module into the subsystem.

8. Insert the cooling module.

9. Plug the PSU cable into the PSU module socket. Turn the power switch on.

6.6 Cooling Module Maintenance

6.6.1 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.

6.6.2 Replacing a Cooling Module

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.

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.
