Hello, guys!
It is nice to meet you in the community!
The topic describes how to configure the device IP address using the serial port on the U19.
Log in to a U1900 series unified gateway using the CLI and access the Config mode.
Run the following command to configure the device IP address:
config system ip mode static address 192.168.1.20/24 gateway 192.168.1.1
When the IP address is changed, the device automatically restarts. After the device is restarted, log in to the device using its new IP address.
Thanks for reading!
