Conﬁguring Telnet software

If you are conﬁguring your router using a Telnet session, your computer must be running a Telnet software program.

■If you connect a PC with Microsoft Windows, you can use a Windows Telnet application or simply run Telnet from the Start menu.

■If you connect a Macintosh computer, you can use the NCSA Telnet program supplied on the Netopia R910 CD. You install NCSA Telnet by simply dragging the application from the CD to your hard disk.

Connecting a console cable to your router

You can perform all of the system conﬁguration activities for your Netopia R910 through a local serial console connection using terminal emulation software, such as HyperTerminal provided with Windows95 on the PC, or ZTerm, included on the Netopia CD, for Macintosh computers.

The Netopia R910 back panel has a connector labeled “Console” for attaching the Router to either a PC or Macintosh computer via the serial port on the computer. (On a Macintosh computer, the serial port is called the Modem port or Printer port.) This connection lets you use the computer to conﬁgure and monitor the Netopia R910 via the console screens.

It is difﬁcult to specify the address that will be served to a particular client in all circumstances. However, when the address server has been conﬁgured, and the clients involved have no prior address serving interactions, the Netopia R910 will generally serve the ﬁrst unused address from the ﬁrst address pool with an available address.
