Status Indicators
When power is applied to the ERn enclosure, the Paradigm repeater module LEDs located
on the front panel illuminate, indicating the status of the auxiliary power, LinkPower control
network, and connected stations.
The Aux Power and LinkPower LEDs indicate in green when the Paradigm station power
module is connected properly and auxiliary power and LinkPower are present. When there
is an unbalance in LinkPower the fault indicators illuminate. This condition typically means
that the station wiring is at fault, however it could mean a connected device is having an
issue. A qualified technician should inspect the system wire and terminations first, then
proceed to disconnecting devices to pinpoint the fault and correct it. The power supply will
update the fault indicators automatically when the fault condition is cleared.
• If the NET A line has a fault (is shorted or has leakage to ground), the Fault + LED
lights.
• If the NET B line has a fault (is shorted or has leakage to ground), the Fault - LED lights.
• If neither fault LED is illuminated the data connections are properly installed and the
stations are receiving the data and power required for operation.
