2.2 Power supply
The IRTrans Ethernet PoE may be supplied with power by an IEEE 802.3af con-
formal Power over Ethernet switch. According IEEE802.3af the power may be
supplied by a free conductor pair as well as by a data pair.
Older switches not conforming to IEEE802.3af may not be usable to power the
IRTrans PoE.
For an external power supply there is a 5.5/2.5mm hollow connector. The exter-
nal power supply should be capable of delivering 4,5-6V with approximately
300mA. The positive lead must be wired to the center terminal.
If there is power available either via PoE or by external supply the blue
LED next to the power connector will be lit´.
The IRTrans Ethernet PoE requires a different voltage power supply
compared to other IRTrans modules. For this reason the power connec-
tor is 5,5/2,5mm.
