Independent Mode Redundancy

The use of Independent mode to configure redundancy for the module avoids the
need for ALARM IN/ALARM OUT hard-wiring to define the Master-Slave
relationships between receiver channels.
The only additional hardware requirement for Independent mode redundancy is
that every chassis in the configuration must be connected to the same ICIM domain
using an appropriate interconnect cable (part number 180143 or equivalent) through
the chassis ICIM IN and ICIM OUT ports.
Note:
Every chassis that does not have an ICIM installed but has an open ICIM IN or

ICIM OUT connector on the back panel must have an ICIM bus terminator, part
number 4013014 or equivalent, installed in the open ICIM connector (one
terminator per chassis is sufficient).
The ICIM itself is needed only to configure modules for redundant operation. It

is not required to support actual redundant operation.
