Connecting the Router to the WAN 27
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.
Connecting the Router
to the WAN
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)
Connecting the AUX
Port to the Modem
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.
