6.4 POWER SUPPLY AND CABLE
ALFOplus unit is compatible with standard POE + IEEE 802.at (with exceeding maximum power). Power
supply can be provided at the LAN1 (ALFOplus GE) or LAN2 (ALFOplus GO).
In case of external PoE injector, verify that it has overcurrent protection. Power supply can be provided at
the LAN interface or at an auxiliary separated connector at the same time. The maximum length of CAT5e
cable (that carries data+PoE) is 100m.
