Router to WAN
Connection
Many types of WAN interfaces are available with the Router 6000 and the
one provided by the main control boards is an AUX interface. The
following subsections describe how to connect it. For connecting the
WAN interface on a FIC, refer to the relevant contents in the chapter
“FICs”.
AUX port
AUX is an RS232 asynchronous serial interface, which can back up a
WAN interface and provide dial connection. In case of console failure,
AUX can function as a console interface. For the AUX interface attributes,
refer to the section “The RPU Module” or “The RPU2 Module”.
AUX cable
AUX cable is an eight-wire shielded cable. At one end of the cable is an
RJ-45 connector for connecting the console port on the router. At the
other end are DB-9 (male) connector and DB-25 (male) connector. You
can plug either of them into the serial port on a modem as needed. The
following figure illustrates the AUX cable.
