Connecting the switch to the network through the AUX port
You need an AUX cable when configuring a switch with the remote modem dial-up approach.
Introduction
An AUX cable is an 8-core shielded cable. At one end of the cable is an RJ-45 connector and at the other end is a DB-9 (male) connector. Plug the RJ-45 connector into the AUX port of the switch and the DB-9 (male) connector into the DB-9 (female) port of the modem. An AUX cable is the same as a console cable. For more information, see Figure 34 and Table 9.
Connection procedure
To connect the AUX port:
Plug the RJ-45 connector of the AUX cable into the AUX port of the switch.
Plug the DB-9 (male) connector at the other end into the serial port of the modem.
