Netopia R2121 Adding a third modem

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.
