Accessing The Switch For The First Time; Setting Up The Configuration Environment; Connecting The Console Cable - H3C S6820 Series Installation Manual

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.
