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 an IEEE 802.3af device connected to the
pass-through port on the IntelliJack, but it will not provide power to the
IntelliJack.
Using an Ethernet Multi-port Midspan Power Supply
To use an Ethernet multi-port midspan power supply, you must connect the
power supply to your network, as shown in the following illustration.
The Ethernet multi-port midspan power supply from 3Com connects to an existing
Ethernet or Fast Ethernet infrastructure with standard Category 5 or better
cabling, and powers up to 24 IntelliJack devices. For complete installation
instructions, see the Ethernet multi-port midspan power supply documentation
located at www.3Com.com.
