Background
Section titled “Background”This alarm means the distro hover configuration checker associated more than one hover identity with a single expected hover corner.
This is commonly accompanied by one or more *_DUPLICATED alarms that identify the affected corner.
This usually indicates that the hover installation, wiring, or role / provisioning information does not match the expected one-hover-per-corner configuration.
See DISTRO HOVER CONFIGURATION CHECKER for a description of how the diagnostic works.
