Connecting the AUX
Port to the Modem
When connecting the router to a hub or a LAN switch, use the straight-through
network cable.
3 Connect one end of the Ethernet cable to the appropriate Ethernet module on the
router.
4 Connect the other end of the Ethernet cable to the Ethernet interface of the Hub
or the LAN switch.
5 Verify the connection by checking that the 100M ETH LED on the top of the router
is on.
The Router 3000 series routers provide the following WAN interfaces:
AUX port (all models)
■
Mutiprotocol synchronous/asynchronous serial port (Router 3012, Router
■
3013, Router 3015)
ISDN S/T (Router 3013)
■
ISDN U (Router 3015)
■
CT1/PRI ( Router 3016)
■
The auxiliary (AUX) port is an EIA/TIA-232-compliant sync/async serial interface
that is used for remote configuration or dial-up backup. To be connected to a
remote device, a local modem must be connected to a remote modem through
PSTN. For the connection method, see Chapter 4, Booting and Configuring the
Router. If the console port fails, the AUX port can also serve as a console port. For
AUX port specifications, see Chapter 1, Overview.
The AUX cable is an 8-core shielded cable. One end of the cable has an RJ-45
connector and connects to the AUX port of the router. The other end has both a
DB-25 (male) adapter and a DB-9 (male) adapter. Use the appropriate connector
for the port on the modem.
Figure 6 illustrates the AUX cable.
