Connecting Your Local Area Network 5-5
■ If you add devices connected through a hub, connect the hub to Ethernet port number 1 on the Netopia
R2121 and set the Normal/Uplink switch to Uplink.
When there are no more free ports on the 10Base-T hub, the network can be extended using EtherWave, a daisy-chainable
Ethernet solution from Farallon.
Adding a third modem
You may wish to add a third (external) modem to gain additional speed for your Internet connection. You will
need to obtain the special external modem cable either from your reseller or directly from Netopia. Refer to the
sheet of optional feature set add-ons in your Netopia R2121 documentation folio.
Netopia R2121 Auxiliary port for connecting a third modem
By default, the Auxiliary port on your Netopia R2121 is enabled for an external asynchronous modem. This
means that all you have to do is connect your modem to the Auxiliary port and configure its settings in the Line
Configuration screens under the WAN Configuration menu. For detailed configuration instructions see
“Specifying telephone connections” on page 9-2.
