Checking the Duplicating Operation of Modules
This section describes how to check if the system runs properly after system installation or reinstallation.
CPU/IO module has a processor function part and IO function part.
Tips
Processor function part and IO function exists in the CPU/IO module, which monitor and

This section describes how to confirm the continuous system operation by failover after stopping the primary
I/O module.

Check which is the primary I/O module.
The I/O module with the PRIMARY LED lit is the primary module.
2.
Check whether the I/O modules are duplicated.
To check if the I/O modules are duplicated, see the System FT LED.
