CAUTION: The NBX system operates over the LAN, not through traditional
telephone wiring. Your telephone connects to the NBX system through an
RJ-45 LAN connector instead of an RJ-11 telephone connector. Your
telephone will not work unless it is connected properly. Ask your
administrator if you have questions about your telephone connection.
The underside of an NBX telephone or attendant console includes:
1 AC power adapter connection (optional on the 3101, 3102, and 3105)
2 Ethernet connector for connection to the LAN
3 Ethernet connector for an optional connection to your desktop computer
4 Handset connector
5 Headset connector (3102 only)
6 Tabs for the support bracket

For information about the underside of each NBX Telephone, and for

Console to a Power over Ethernet source, see the packing sheet that
comes with the device.
