1.4.3 Power supply connection

Open

Connection of the power supply

There are 2 options for supplying power to the GT7 terminal:

1. Via a separate power supply.

2. Via Power over Ethernet (PoE).

 For PoE, consider the following requirements:

• Must comply with IEEE 802.3af

• Power class: 0

• Min. 15.4W per PoE port

Please note that some PoE switches do not transmit the power voltage on separate wires (DC+ and DC-) but superimpose it on the transmit and receive lines (RX+/- and TX+/-). In this second case, the GT7 terminal is supplied with voltage even if only RX and TX are connected.

Depending on the Ethernet standard being used, terminate the wire colors of the Ethernet cable to the “ETHERNET PoE” screw terminals as follows:
