This action is used to added a WAN3 expansion module. If when a WAN3 is added to the system, the WAN3 is not recognised following a system reboot, New on this form can be used to scan for the WAN3 module.
This action can only be used with external expansion modules. It cannot be applied to the control unit and modules inside the control unit. The action should used with caution as deleting an expansion module will also delete any extensions or lines associated with that expansion module. If the module is physically present, those entries will be recreated following a reboot but with default settings.
