When replacing media in a Neo magazine, the Neo would not read the media bar code labels and would 'physically' inventory ( touch) each media slot. Neo Web TLC or magazine status from operator GUI would show a black stripe on the media slot.
Powering cycling the Neo would result in proper bar code scanning verified via WEB TLC or operator GUI.
