PoE save your power infrastructure cost:
PoE allows power to be supplied to end devices, such as wireless access points or VoIP phones, directly through the existing LAN cables. By supplying the power end-span, you can centralize power distribution and backup without the need to increase infrastructure.
PoE features 1. Supports IEEE 802.3af compliant. 2. Supports power over ethernet (PSE) on each PoE-TP port (end-point). 3. Full power(15.4w) support for per PoE-TP port. 4. Auto detect powered device and consumption levels. 5. Smart feature for PD on/off, PD detection, power level, PD status and power feeding priority. 6. Automatic fault detection(over/under voltage & current). 7. Thermal shutdown protection(Tj > 150c). 8. LED indicators for and PoE activity.
