Replacing The module involves removing the old module and mounting a new one in its place
You can replace the communication module at any time using another module with compatible firmware. A module can be replaced when power to the module is either:
-
off (cold swap), or
-
on (hot swap)
The replacement module obtains its operating parameters over the backplane connection from the CPU. The transfer occurs either immediately (hot swap) or when power is next cycled to the device (cold swap).
NOTE: Operating parameters, that were added to the configuration using explicit messaging “SET” commands, are not included in the parameters that the CPU sends to a replacement module.
