♦The SmartSwitch™ Router 250
The SmartSwitch™ Router 250 provides Internet and Corporate
access for telecommuters, home and remote office workers, and
Internet users at high-speed asymmetrical data rates of up to 640 Kbps
upstream and 8.0 Mbps downstream.
The router takes full advantage of Asymmetric Digital Subscriber
Line (ADSL) technology and uses Asynchronous Transfer Mode
(ATM) to provide remote Ethernet LAN connectivity via a single
ADSL line. Because ATM technology supports multiple virtual circuit
connections, users connected to an Ethernet LAN can access several
network services simultaneously.
♦Cabletron Quick Start
The router features an easy-to-use Windows-based management
application. It also has several built-in features that let users connect
to a Network Service Provider (NSP) in minutes.

ROUTER CONFIGURATION

15
If IP routing and NAT are enabled, you will be prompted to
enter a Source WAN IP Address. You will obtain this
information from your ISP or your Network Administrator.
If NAT is OFF, you may still need to enter Source WAN IP
Address information. You will obtain this information from
your ISP or your Network Administrator.
• RFC 1483MER (MAC Encapsulated Routing)
If MER is selected, you will be prompted to enter a Source
WAN IP Address. You will obtain this information from
your ISP or your Network Administrator.
3. Internet Account (PPP only)
Enter the following information to configure your router for
accessing the Internet:
•User Name
•Password
4. DNS Information
Enter this information (available from your ISP) for accessing
the Internet.

16
•Domain Name
•Server Address
•Second Server
5. Options
The following options are also availablefor further configuration
of the router. Click Options Menu to access them.
•Select Router to Configure
This application will attempt to contact the default IP
address of the router (192.168.254.254). You may also
reconnect to another router with a different IP address.
•Change your LAN IP Settings
This field allows you to specify the LAN IP address of the
router that you are configuring. This address becomes active
after you save your changes and reboot the router.
•Change your WAN IP Settings
This allows you to specify the WAN port IP address of the
router that you are configuring and set Network Address
Translation (NAT). This address becomes active after you
save your changes and reboot the router.

17
•Choose a PVC
The Quick Start application defaults the VPI/VCI numbers
to 0 and 38 respectively, unless they have been
preconfigured. Your Network Service Provider may have
decided on different values to use. If the value chosen by
your NSP is not the default value, then enter the VPI/VCI
that you have been given.
•SNMP Options
The Community Name and UDP Port Number may be
changed for security reasons or to allow SNMP monitoring
of a device located on the LAN while running NAT.
Consult with your Network Administrator to determine if
you need to change the default settings.
6. Tools
The following tools are available to perform advanced configura-
tions, file system management, software maintenance, and data
traffic monitoring.
•Terminal Window
The Terminal Window lets you access the Command Line
Interface directly from Quick Start with a customized
terminal emulator.

18
•Execute Script
The router copiescommand files created on the PC and then
executes them on its first startup.
•Backup/Upgrade
Upgrade / Backup allows you to backup the router’s
configuration files as well as easily upgrade the router’s
software (using a built-in TFTP utility).
•Reboot from Network
This tool allows you to try a new version of software before
committing to it by loading this new software from your PC
without writing it to the router’s file system. This tool is
also used to update the router’s bootstrap module.
•Port Monitor
Port Monitor provides graphic feedback on the operating
status and bandwidth utilization of your router.
7. Exit Quick Start
Click Exit. This saves the configuration information you just
entered and reboots the router.

8. Restart your PC
After the router has successfully rebooted, you must restart your
PC if you have entered DNS information (see Step 4): the PC
will acquire the DNS (Domain Name Server) information from
the router.
