ABOUT THIS GUIDE

This guide describes the 3Com® Router 3000 Family of routers and how to install

hardware, configure and boot software, and maintain software and hardware.

This guide also provides troubleshooting and support information for your router.

This guide is intended for the system or network administrator who is responsible

for configuring, using, and managing the routers. It asumes a working knowledge

of wide area network (WAN) operations and familiarity with communication

protocols that are used to interconnect WANs.

1INTRODUCING THE ROUTER 3000

FAMILY

Routers in the 3Com®Router 3000 Family provides the following types of ports:

■Ethernet port

■Synchronous/asynchronous serial port

■Auxiliary (AUX) port

■ISDN BRI S/T and U port

■CT1/PRI port

■E1/CE1/PRI port

These features allow you to combine the various networking technologies, such as

PSTN/ISDN, FR (Frame Relay), X.25, leased line, and T1 line. These multiple ports

also allow Router 3000 series routers to interoperate with the products of other

manufacturers.

Router 3000 routers use three types of memory:

■Synchronous Dynamic Random Access Memory (SDRAM) — Saves router

operation system software

■Flash memory — Saves router program files, configuration files and so on

■Boot ROM — Saves the boot and initialization programs of the router
