n The PC serial port is not hot-swappable, so you are not allowed to insert or remove the console cable into or from the PC serial port.

When connecting the console cable, first connect the DB9/DB25 end to the PC serial port and then the RJ45 end to the console port of the switch. And removing the console cable is just in inverse order.

When removing the console cable, first remove the RJ-45 end and then the

DB9/DB25 end.

Connecting AUX Cable You need an AUX cable when configuring the Switch 8800 Family with the remote modem dial-up approach.

Introduction

AUX cable is an 8-core shielded cable. At one end of the cable is an RS-232-compliant RJ-45 connector that can be plugged into the console port of the switch. At the other end are DB-9 (male) connector and DB-25 (male) connector. You can plug either of them into the DB-9 (female) or DB-25 (female) port of the modem as needed. The following figure illustrates the AUX cable.
