6.3 POWER SUPPLY AND CABLE
ALFOplus unit is compatible with standard POE IEEE 802.3af (with exceeding maximum power). Power sup-
ply 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.

In any case, for other different needs, a dedicated auxiliary port (5 pin connector) provides power supply
48Volt (see Fig.50
). For installation, please use rugged and waterproof cable.
6.3.1 POE units
ALFOplus 24GHz can be supplied by PoE units; in Tab.7 there is a list of suggested PoE units (all the PoE
units are protected against short circuit, overvoltage, overcurrent).
Tab.7 - List of suggested PoE units
PoE units different from suggested can be used but they shall guarantee short circuit, overvoltage, over-
current protection.
