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.
Insert the new PSU module into the subsystem: Once the previously removed cooling
module has been installed, insert the new PSU module into the subsystem. Make sure the
extraction lever is in its downright position so that the saddle notches on the lower edges
of the handle can lock on to the edge metal brackets along the chassis inner walls. Push
the PSU into the slot and pull the handle upwards to secure the module.
Reinsert the retention screw: If the PSU module is properly installed, the back end of the
module should be aligned with the enclosure's rear panel. To firmly secure the PSUs into
place, reinsert the retention screw.
Reconnect the power cord and turn the power on: Plug the power cord into the socket on
the PSU module and turn the PSU module power switch on.
Redundant cooling fan modules: The subsystems are equipped with two redundant, hot-
swappable, single-blower cooling fan modules located in the lower PSU module slot.
These cooling fan modules control the internal operational temperature of the subsystem
and therefore their working integrity should be maintained at all times.
Detecting a failed cooling fan module: If a cooling fan module fails, you can be notified of
the failure by the LED located at the back of the module, an audible alarm, the terminal
event prompts, the Bosch RAIDWatch Panel View, or through the various methods by the
Configuration Client utility.
Replacing a cooling fan module: Once you are notified that a cooling fan module has
failed, it should be replaced as soon as possible. A failed cooling fan module should only
be removed from the subsystem when you have an immediately available replacement
module that can be installed as soon as the failed cooling fan module has been removed.
The latches at the back of the cooling fan module secure the cooling fan module into the
enclosure. If these latches are broken, the warranty on the cooling fan module will be
void.
Although the cooling fan modules are fully redundant, it is not advisable to run the sub-
systems with any of the cooling fan modules missing. Whenever a cooling fan 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.
