Green/Off
The system is experiencing temporary network
errors. This condition normally corrects itself. If the
condition persists, check your nodes and cable
system. When checking the cable system, make
sure:
•
All BNC connector pins are properly seated.
•
All taps are connected properly.
•
All coax terminators are 75 ohms and installed at
both ends of all coax segments.
•
Coax cable has not been inadvertently grounded.
Red/Off
The system is experiencing a high level of network
errors. Check for broken cable or tap, and missing
segment terminator.
(Note that this is a
normal
indication for a system
that has
no
ControlNet nodes installed or enabled,
since it has
no
network activity. It is also a normal
indication for a Repeater Adapter used in a Hub
serving as a fiber-to-fiber repeater with no coax
cable connected.)
