Removing and Replacing Enclosure Components
Hot-swapping an APC Module
This section provides basic information about your Storage
Enclosure’s APC modules, including removal and installation
instructions.
About the APCs
Each APC is a self-contained power supply with an integral
cooling fan. Your Adaptec Storage Enclosure includes two APCs,
located on the rear of the enclosure, as shown in
Figure 4-1 APC Module
Your Adaptec Storage Enclosure requires both APCs to be running
for proper operation and cooling. However, it can run with a single
APC for a brief time period, long enough to replace the other APC
in the event of a failure.
An APC module failure can be caused by failures of the power
supply or one or more of the cooling fans. Other types of failures
are also possible. The cooling fans in each APC run on separate
circuits from the power supply and run on power supplied by the
other APC module in the event of a failure.
Failed APC modules can be hot-swapped.
