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
