 Note:
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.

You need an AUX cable when configuring the S8500 series with the remote modem
dial-up approach.
I. Introduction

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
