Controller enclosure — rear panel layout
The diagram and table below display and identify important component items that comprise the rear panel
layout of an S3200/S2200 controller enclosure. In Figure 38 below, a S3200 CNC model is shown as a
representative example. Diagrams and tables on the following pages describe rear panel LED behavior.
The rear panel layout applies to 2U24 and 2U12 chassis form factors.
Figure 38 S3200/S2200 controller enclosure: rear panel
A controller enclosure accommodates two AC power supply CRUs within the two power supply slots (see
two instances of callout No.1 above). The controller enclosure accommodates two controller module CRUs
of the same type within the I/O module (IOM) slots (see callouts No.2 and No.3 above).
IMPORTANT: If the S3200/S2200 controller enclosure is configured with a single controller module, the
controller module must be installed in the upper slot (see callout No.2 above) and the I/O module blank
must be installed in the lower slot (see callout No.3 above). This configuration is required to allow sufficient
air flow through the enclosure during operation (also see Figure 12 on page 25).
The diagrams with tables that immediately follow provide descriptions for the different controller modules
and power supply modules that can be installed into the rear panel of an S3200/S2200 controller
enclosure. Showing controller modules and power supply modules separately from the enclosure enables
improved clarity in identifying the component items called out in the diagrams and described in the tables.
LED descriptions are also provided for optional drive enclosures supported by the S3200/S2200 controller
enclosures.
For information about replacing S3200/S2200 controller enclosure CRUs, refer to the appropriate CRU
replacement procedure in the CRU Installation and Replacement Guide.
