(cont.) Stop Service
Received A non-redundant module is
placed into a redundant
secondary chassis. The
module was commanded to
stop functioning by the
redundancy module
(RM/SRM). 1. Remove the non-redundant
module from the redundant
secondary chassis
2. Replace the non-redundant
module with the redundant
module.
This could occur if a
1756-CN2/R module running
Boot code is inserted into a
chassis along with a
1756-SRM or 1756-RM
module.
For Redundant Control, the
1756-CN2 series B module is
designed to interoperate with a
1756-RM module. It should not be
used with a 1756-SRM module.
1. Insert the module into a
chassis that does not
contain a 1756-SRM or
1756-RM module.
2. Update the module’s
firmware using
ControlFLASH.
