Rear panel LEDs
Controller enclosure—rear panel layout
The diagram and table below display and identify important component items comprising the rear panel
layout of the MSA 2040 controller enclosure (MSA 2040 SAN is shown in the example). Diagrams and
tables on the following pages further describe rear panel LED behavior for component field-replaceable
units.
Figure 34 MSA 2040 SAN Array: rear panel
A controller enclosure accommodates two power supply FRUs of the same type—either both AC or both
DC—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: If the MSA 2040 controller enclosure is configured with a single controller module, the
controller module must be installed in the upper slot (see callout 2 above), and an I/O module blank must
be installed in the lower slot (see callout 3 above). This configuration is required to allow sufficient air flow
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 2040 controller enclosure.
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 2040 controller enclosures
for expanding storage capacity.
1 AC Power supplies [see Figure 38 (page 80)]
2 Controller module A [see Figure 35 (page 77)]
3 Controller module B [see Figure 35 (page 77)]
