Accessing the switch for the first time
Connecting the switch to a configuration terminal
The following options are available for connecting the switch to a configuration terminal:
•
Use a serial console cable to connect the serial console port on the switch to a configuration
terminal.
•
Use a mini USB console cable to connect the mini USB console port on the switch to a
configuration terminal.
Only the mini USB console port is active if you connect both the serial console port and mini USB
console port.
The example uses a serial console cable to connect a console terminal (PC) to the serial console
port on the switch.
Figure3-1 Connecting the serial console port to a terminal
As shown in Table3-1, three types of console cables can be used for connecting the switch to a
configuration terminal. The switch is not provided with a serial console cable or a mini USB console
cable.

The signal pinout for the RJ-45 connector of a serial console cable varies by vendor. To avoid
abnormal configuration terminal display, use a serial console cable provided by H3C. For more
information, see Table3-2. To prepare a serial console cable yourself, make sure the signal pinout for
the RJ-45 connector is the same as that shown in Table3-3.
