Powering
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.
