Solution¶
This alarm usually indicates that an option card (3200) or expansion box (400) has been removed from the appliance. If no devices have been removed, this could also indicate a communication problem with the option card or expansion box.
Shut down your appliance with the shutdown command or from the front panel. If the option card or expansion box is still attached, carefully remove it from the appliance. Option cards have two thumb screws on the front that need to be loosened.
Reinstall the option card and tighten thumb screws.
Power the appliance on and check alarms.
