Power Options

Using an Integrated Switch with Power Over
Ethernet

To use Power Over Ethernet, you must have a switch on the
network that has Power Over Ethernet integrated into it.

Connect the network data/power cable to the IntelliJack white
cable, as shown in the following illustration.

NOTE

: The black cable can also be connected to

an Ethernet multi-port midspan power supply
and will power a PoE compatible device
connected to the pass-through port on the
IntelliJack, but it will not provide power to the
IntelliJack.
