Checking the LEDs 13
Connecting Devices to
the Network Jack
After the Network Jack 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 Network Jack.
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 Network Jack 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
Network Jack is forwarding power to a connected device.
