A Control Card redundancy request is initiated by selecting the status block for the
desired Control Module. (The block is highlighted to show selection.) Next, you
select the Redundancy Request button to bring up a set of commands described
below:
Establish Redundancy - Establishes redundancy.
Terminate Redundancy -
Also terminates the Redundancy Auto-Establish
mode.
Start Controller - Used to get out
of the READY state.
Hard Reset - Causes the Control Module
to reset. This command is similar to
pulling the Control Module out of the slot and then re-inserting it.
Fail Over
- Requests fail over of the Primary Control Module to the Backup
Control Module. If the fail over is unsuccessful, the Primary Control Module
continues to function as if no request to fail over occurred.
Switch Back
- Requests switch back from the Backup Control Module to the
Primary Control Module.
Confirm - Co
nfirms and sends request to the subdevice.
Cancel - Cancels an
y request not yet confirmed.
When one of the above commands is selected (except Confir
m and Cancel), the
request and the subdevice number are shown and a prompt is displayed requesting
confirmation of the selected action. If the action and selected module are correct,
then select Confirm. Otherwise, select a different action and/or module.
