3 Accessing the switch for the first time 
Connecting the switch to a configuration terminal 
You can connect the switch to a configuration terminal by using the serial console port or the micro 
USB  console port. Only the micro USB console port takes effect if you connect both the serial 
console port and micro USB console port. 
In Figure3-1, the switch is connected to a configuration terminal (PC as an example) from the serial 
console port. 
Figure3-1 Connecting the switch to a configuration terminal 
 
 
As shown in Table3-1, three types of console cables can be used for connecting the switch to a 
configuration terminal. As a best practice, use a serial console cable for connection. The switch is not 
provided with a serial console cable or a micro USB console cable. Purchase a serial console cable 
from H3C or prepare a micro USB console cable yourself.
