Powering over Ethernet
LM5 supports two powering modes:
- regular powering over screw terminals (Jumpers up or down)
- passive PoE powering over 24V DC (Jumpers down)
- when using active PoE 48V, jumpers have to be UP or the product will be damaged!
Please note that there are two PoE types of PoE switches/adapters – passive and active (802.3af).
In passive mode 4 Ethernet cable wires are used for data and 4 are used for power. In active PoE
mode data and power goes together.
