Review the contents for any damages. When in doubt, don't use the devices.
•
To avoid problems with warranty, always use the power supply adapter 48VDC, which is part
of delivery. Never use other type of power supply adapter.
•
Beware of the reverse DC power supply adapter polarity: Never reverse the polarity of the DC
power supply adapter when connecting it to the 2-Wire-LAN device. If you reverse the polarity,
the warranty is void/invalid.
•
Make sure the legacy 2-wire cable follows the correct + and – polarity as shown on the 2-Wire-
LAN device. If you reverse the polarity, the warranty is void/invalid.
•
Do a dry run first: Take out the two (or more) 2-Wire LAN devices, the 48VDC power supply,
the primary power connector, a short pair of power wires, and a small screwdriver.
Installation
•
Connect the green connector with a pair of power wires.
Make sure that plus and minus are not switched. There is no
correct plus and minus for this. It's more important not to cross
the wires when connecting them.
•
Plug both connectors into the two 2-Wire-LAN devices.
•
Connect the power supply unit with one of the two devices.
•
Now connect the main power connector with the power supply adapter and the power
When the power is plugged on, the devices are in automatic coupling mode and
•
As soon as the power LED and TWP LED of both devices are on, the two devices are
connected.
•
You can now connect two devices to the LAN interfaces for testing. This could be a switch or
your router on the one hand, or a laptop or other LAN device on the other hand. Since the
system also supplies PoE power according to IEEE 802.3af/at, the connected device could
also, for example, be an IP camera, an IP phone, or an IP intercom.
The lighting of the PoE LED shows that a LAN device is connected. The blinking of the PoE
and TWP LEDS shows that data is flowing.
•
To connect a third (or additional) device (that hasn't been in operation yet), disconnect the
power from the power supply unit
•
Remove the green connector of one of the two devices
•
Plug the green connector into the third (or additional) device
•
Plug-in the power of the power supply adapter again
•
The third (or additional) device is now also connected
