Status Indicators
When power is applied to the ERn enclosure, the Paradigm Station 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 has a
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.
Install Redundant Power Supply
The ERn Redundant Power Supply (ERn-RPS) is an additional rack power supply that powers the ERn
enclosure if the primary rack power supply is removed or fails.
Note:
The Redundant Power Supply (ERn-RPS) is not supported in an ERn4 rack enclosure
at 230 VAC. Instead, the ERn4 rack at 230 VAC requires two rack power supplies
installed in the top (normal) position and in the lower rack option module slot as
standard.
Install the Redundant Rack Power Supply in the bottom option slot
of the ERn enclosure and secure it in place with the two captured
screws.
