Controller enclosure—rear panel layout
The diagram and table below display and identify important component items comprising the rear panel layout of the
MSA 1050 controller enclosure. The example configuration shown in Figure 27 uses FC SFPs. Diagrams and tables on the
following pages further describe rear panel LED behavior for component field-replaceable units.
Figure 27 MSA 1050 Array: rear panel
A controller enclosure accommodates two power supply FRUs within the two power supply slots (see two instances of
callout 1 above). The controller enclosure accommodates two controller module FRUs of the same type within the I/O
module slots (see callouts 2 and 3 above).
IMPORTANT: MSA 1050 controller enclosures support dual-controller only. If a partner controller fails, the array will
fail over and run on a single controller until the redundancy is restored. A controller module must be installed in each IOM
slot to ensure sufficient airflow through the enclosure during operation.
The diagrams with tables that immediately follow provide descriptions of the different controller modules and power
supply modules that can be installed into the rear panel of an MSA 1050 controller enclosure. The controller module for
your product is pre-configured with the appropriate external connector for the selected host interface protocol. Showing
controller modules and power supply modules separately from the enclosure provides improved clarity in identifying the
component items called out in the diagrams and described in the tables.
Descriptions are also provided for optional drive enclosures supported by MSA 1050 controller enclosures for expanding
storage capacity.
