What is sc5000ShelfClockMode?

This read-only field reports which LTU is currently supplying the shelf clock: the primary unit, the fallback unit, or none if neither assigned card is present. Admins monitor this to detect when the shelf has failed over to its backup timing source, signaling a problem with the primary LTU. For example, a value of fallback(2) tells an admin the primary timing card has failed or been removed and the shelf is now running on backup timing.
