Removing and replacing the fan module
There are two fan modules: one server fan module, which cools the server half of the enclosure,
and one hard drive fan module, which cools the drive half of the enclosure. The two fan modules
are not redundant for each other.
CAUTION:
of the system may occur. The total time allowance is three minutes for replacing the fan module,
which includes the removal of the original server fan module and installation of the replacement
fan.
Removing a fan module significantly changes the air flow within the enclosure. Both fan modules
must be installed for the enclosure to cool properly. The fan modules are not redundant to each
other, and each module cools a different half of the enclosure. If a single fan module fails, leave
it in place in the enclosure until a new fan is available to install. The fan modules have some built-in
redundancy to keep operating until a replacement can be made. The remaining fan module speeds
up and allows operation for a limited time, based on operating and environmental conditions. If
a temperature threshold is exceeded, the enclosure automatically shuts down.
