Interpret Status Indicators
The status indicators on the card give you information about the card and the network when
the card is connected to the network with the BNC connectors. Table 7.1 outlines the states
and explains what each state means to you and the action you should take, if any, to correct
that state.
• steady - indicator is on continuously in the defined state.
• alternating - the two indicators alternate between the two defined states at the same
time (applies to both indicators viewed together). The two indicators are always in
opposite states, out of phase.
IMPORTANT
When you connect the module to a ControlNet network using only the
network access port (NAP), the status indicators are meaningless.
