Accessing the switch for the first time
Setting up the configuration environment
You can access the S5150-EI switch through the serial console port or the mini USB console port. As
a best practice, use the serial port to access the switch. To access the switch through the mini USB
console port, you need to prepare the mini USB console cable.
Only the mini USB console port takes effect if you connect both the serial console port and mini USB
console port.

Connecting the console cable
A console cable is an 8-core shielded cable, with a crimped RJ-45 connector at one end for
connecting to the 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.
