6.6 Cooling Module Maintenance
6.6.1 Cooling Module Overview
• Redundant cooling modules: The RAID subsystem is equipped with two (2) redundant,
hot-swappable, dual-blower cooling modules located on the lower level of the subsystem
rear panel. 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, the LED located at the back
of the module, an audible alarm, the firmware, the Bosch RAIDWatch panel view, 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.
6.6.2 Replacing a Cooling Module
If one of the cooling modules fails, it must be replaced as soon as possible. The cooling mod-
ules are secured to the chassis with the two (2) black latches located on the rear surface of
the module itself. To replace the cooling module, please follow these steps:
1. To remove the cooling module, pull both side latches toward the center of the cooling
module. Withdraw the cooling module from the subsystem by gently pulling on the silver
handle at the bottom of the module. (See Figure 6.17)
Fig. 6.17 Removing the Cooling Module
2. Install the new cooling module by aligning the module with the cooling module slot on
the lower section of the PSU module and gently sliding it in. The latches will hold the
module in place. (See Figure 6.18)
CAUTION!
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.
CAUTION!
• Although the cooling modules are fully redundant, it is not advisable to run the RAID sub-
system with a single cooling module for an extended period of time. If the remaining cool-
ing 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.
