CAUTION
DO NOT disconnect the media of the surviving channel of a dual media network when a media
fault occurs and the system is ON-LINE. For example, if the “A” channel is faulty and requires
troubleshooting, DO NOT disconnect anything on the “B” channel (trunks, drops, terminators)
while the system is ON-LINE.
DO NOT disconnect the media (trunks, drops, terminators) of single media networks while the
system is ON-LINE.
All ControlNet BNC connections require a “push-on, twist, and lock/snap” sequence.
Connections not locked/snapped may result in improper ControlNet network operation.
