terminal where the switch is to be configured.
Step 2: Connect the RJ-45 connector of the Console cable to the Console port of the

4.6.2 Connecting the COM Port Cables
I. Introduction
COM port cable is an 8-core shielded cable. One end of the cable is crimped with an
RJ-45 connector, for connection with the COM port of the switch; the other end is
attached with a DB-9 female connector and can be inserted to 9-pin male connector.
The COM port cable is the same as the Console cable.
