Connecting Console Cable

Introduction

Console cable is an 8-core shielded cable. At one end of the cable is a crimped RJ-45 connector that is to be plugged into the console port of the switch. At the other end of the cable are a DB-9 (female) connector and a DB-25 (female) connector. You can plug either of them into the 25-pin (male) or 9-pin (male) serial port on the console terminal as needed. The following figure illustrates the console cable.
