Powering the Switch from a PoE Source
Connecting the Switch to an External DC Power Source
Any of the eight 10/100/1000 RJ-45 ports (ports 1~8) that are PoE PD supported
can be used to receive power for the switch from a connected PoE PSE device. The
PSE device supplying power must conform to the IEEE 802.3at-2009 PoE
specifications.
Note:
If the switch receives its DC input power using PoE, then IEEE 802.3at-2009
PoE specifications require Category 5 or better cabling.
To supply DC power to the switch, first verify that the external DC power supply can
provide 48 VDC, 0.65 A minimum.
To connect the switch to a DC power source:
