Connecting your switch to the network
This chapter describes how to connect your switch to a network.
The first time you access the switch, you can only log in to the CLI through the console port or USB console
port. After login, you can configure remote access methods, including Telnet and SSH.
You manage console or USB console login users at AUX user interfaces, and manage Telnet and SSH
users at VTY user interfaces. For more information about login methods and user interfaces, see H3C
S10500 Switch Series Fundamentals Configuration Guide.
Accessing the switch for the first time
The first time you access the switch you must use a console cable to connect a console terminal, for
example, a PC, to the console port or USB console port on the switch.
Setting up the configuration environment
If both the console port and the USB console port are used, you can only access the switch through the
USB console port.
Console cables

The console cable has a crimped RJ-45 connector for connecting to the console port of the switch,
and a DB-9 connector for connecting to the 9-core serial port on the terminal.
Figure 37 shows the console cable and Table 8 shows its pinouts.
