Examples include modems, leased or switched CSU/DSU’s, and ISDN terminal
adapters.
You may select either dial-on demand, redial if down (“always up” mode), or leased
line operation. These ports may also be set to receive ISDN or switched-56
incoming calls.
To connect a device, first make sure that both units are powered off. Then, simply
connect one of the supplied RS-232 data cables (not an auxiliary port cable)
between the router and the device.
v Note: The BR Router RS-232 port requires that your line communications device
be set to supply the RS-232 DCD signal when a connection has been established
with the remote end.
v Note: The BR Router includes a special data cable to facilitate connections to
RS-232 line communications devices. This cable includes support for several
asynchronous and synchronous control signals. Off-the-shelf Sun or Macintosh-
type cables do not support these signals.
Connecting an Out-of-Band Management Console
If you wish to connect an out-of-band management console, use the supplied
auxiliary cable and connect to the AUX port on the back of the BR Router. You can
use a dumb terminal or a computer equipped with VT100 terminal emulation.
The default baud rate for the AUX port is 9600.
Powering Up the Router
Power up all modems, CSU/DSU’s, and TA’s before powering up the router. This
allows the router to immediately sense the connected device. At power-up, the
router will take approximately one minute to become visible to RouterView.
v Note: If you want to use Telnet as a management method, you must configure an
IP address into the router using an out-of-band console or RouterView before you
will be able to contact the router.
