ONNECTIONS
The ES-3026P switch is an excellent choice for supplying power to
connected PoE devices such as web cameras, IP telephones, or access
points.
The first six ports on the switch can provide up to 30 W of power to a
connected device. The switch can supply 15.4 W simultaneously to 12 PoE
devices among 24 Fast Ethernet ports, or 30 W simultanesously to six
connected PoE devices. The total power can not exceed 185 W PoE power
budget.
In the figure below, the switch is supplying power to three PoE devices. It
is also providing dedicated 100 Mbps full-duplex data connections to these
devices. In addition, other non-PoE devices can be connected to the switch.
