2.2 Power the Switch
The switch accepts 100-240VAC power. The power supply unit is built-in to the switch to convert AC to DC PoE power and transmit through the Ethernet cable.
8-port 800M switch:
A. Connect the power cord to the rear of the switch, and connect the other end to the AC outlet.
B. All the indicators will be turned on and turned off, only the PWR (power) LEDs will remain ON after a while. You should hear the FAN start running with small noise.
Now the switch is ready to supply the PoE to the edge devices.
