* Connect to the device's serial console port like explained here: [[Cabling_and_Configuring_Opengear_CM4148#Cabling_2]]
* Connect the device's network port ''NETWORK 1'' to your network. There must be a DHCP server running.
* On the serial console, log in with user name <code>root</code> and password <code>default</code>
* Type the command <code>ifconfig</code> and check the IP address that was assigned to interface <code>eth0</code> (that's ''NETWORK 1'') through DHCP. 
* Open that IP address in a browser over '''https'''.
* On the web interface, login with the same credentials as above
* Click ''System''&rarr;''Firmware''
* Select the firmware image file and click ''Apply''
* Wait for the upgrade process to finish
* If after 10 minutes the ''Power'' and ''Online'' LEDs are off and the device won't reboot by itself, disconnect it from power for two minutes and turn it back on again.
* Check the new firmware version has been applied through the web interface.
