Indicator
Description
Action
Solid green
Error-free data is being recovered
at all of the attached repeater

• This situation will normally
correct itself. If the situation
persists, check the following:
• All BNC connector pins are
seated properly.
• All taps are Rockwell
Automation taps.
• All terminators are 75
Ω
and
are installed at both ends of all
segments.
• Coax cable has not been
grounded.
• Fiber-optic connectors are of the
correct type and are correctly
attached to the fiber-optic
cable.
• Fiber-optic cable is the correct
