Connecting the Router
to the Console
Terminal
The Router 3000 series routers provide an EIA/TIA-232 asynchronous serial console
port, through which you can configure the router.
The console cable is an 8-core shielded cable. The end that is used to connect to
the console port of the router has an RJ-45 connector. The other end of the
console cable has both a DB-9 (female) adapter and a DB-25 (female) adapter. Use
the appropriate connector for the port on the console terminal.
Figure 4 illustrates the console cable.
