Accessing the switch for the first time
Setting up the configuration environment
You can access and configure the switch through the serial console port or the micro USB console
port. Only the micro USB console port is available if you connect both the serial console port and
micro USB console port.
As a best practice, use the serial console port to access the switch. The switch is not provided with a
serial console cable or a micro USB console cable. Prepare these cables yourself or purchase them
from H3C.

Connecting the serial console cable
A serial console cable is an 8-core shielded 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.
