Connecting Devices to
the IntelliJack
After the IntelliJack is installed and mounted, connect your networking devices
(such as computers, printers, etc.) to any of the four switched ports on the front of
the IntelliJack.
If you installed the adapter plate with pass-through ports, connect the appropriate
device(s) to the port(s).
Checking the LEDs
You can verify the IntelliJack installation by checking the LEDs.
Additionally, each of the switched ports has a green LED which lights when a
device is connected. Port 1 also has an amber LED which lights when the
IntelliJack is forwarding power to a connected device.
WARNING: Use the local power supply available from 3Com. Failure to do so
may result in damage to the IntelliJack, or may result in a hazardous situation.
