This object reports whether the minor-alarm indicator lamp on the NEC IP-PBX is currently lit (exist) or not (non), reflecting a less severe fault condition than the major lamp. Administrators check this to catch lower-priority issues that still warrant attention but aren't yet critical. For example, seeing this object as exist(2) while the major lamp status remains non(1) would tell an admin there's a minor issue to look into, but nothing urgent yet.
