Redundancy System Assembly
When you assemble the primary and secondary chassis for redundancy, you
assemble them just as you would any ProcessLogix or ControlLogix chassis,
with the exception that for redundancy you need to assemble two identical
chassis.
Connect the Fiber-optic Cable
Prior to installing the 1757-SRM module into the rack, locate the module’s
fiber-optic port and connect one end of the redundancy module cable to it.
For additional information, see the Redundancy Module Cable Installation
Instructions, publication 1757-IN014.
ATTENTION
If you are adding redundancy to an already operational ProcessLogix
or ControlLogix system, shut off your process to install the 1757-SRM
module and designate the primary system.
You may also have to use RSNetworx software to configure keeper
information in the secondary ControlNet communication module if the
master keeper for ControlNet communication is in the primary
chassis.
You may also need to enable redundancy in your RSLogix 5000
software application and remove any I/O modules from the chassis.
