Accessing the switch for the first time
Setting up the configuration environment
You can access the switch through the serial console port or the mini USB console port. As a best
practice, use the serial console port to access the switch. To access the switch through the mini USB
console port, you need to prepare a mini USB console cable yourself.
The example uses a console cable to connect a console terminal (PC) to the serial console port on
the switch.

Connecting the console cable
A serial console cable is an 8-core cable, with a crimped RJ-45 connector at one end for connecting
to the serial console port of the switch, and a DB-9 female connector at the other end for connecting
to the serial port on the console terminal.
