Powering Using an Optional External Power Supply
• Attach the "PoE + DATA" port to a spare port on the Dante network
switch using a CAT-5 cable.
• Attach the power supply to the power input jack and then power up
the external supply.
The front power LED will be illuminated once power is applied correctly.
Network LED Indicators
Both Dante ethernet interface port LEDs will remain off if there is no
Dante network connection. If an active connection is made, both LEDs
will light up. If there is network activity, the yellow LED will flash.
Dante Daisy Chaining
The EP40-D allows for the daisy chaining of up to six devices. Connect
an ethernet cable from the "DATA" port of the EP40-D to one of the
ports of the next EP40-D to be chained.
To daisy chain power, attached the "LINK OUT" connector to the "LINK
IN" connector on the unit being added. Note the following limitations:
• PoE – If power is supplied to the first device via PoE, the daisy chain
is limited to three units total – the initial device plus two others.
• Standalone power supply – If the first device is powered by a
standalone power supply, the maximum output of that power supply
determines the number of devices it can support (assume 4 W at
24 V DC per device).
