Manually updating firmware on a CPE device

When following these steps, you are prompted to enter the CPE device credentials. After registration, the default password of the CPE device is automatically changed. You can view the CPE device password in the orchestrator web interface.

To manually update the firmware on a CPE device:

Download the firmware archive from the /cpe directory of the distribution kit to the administrator device, for example, your laptop. If you do not know which firmware version you need to install on the CPE device, use the table of correspondence of CPE device models with firmware versions.
Connect the administrator device to the LAN port of the CPE device.
The administrator device gets the IP address of the default gateway via DHCP. The received IP address of the default gateway is the IP address of the CPE device.
Connect to the CPE device over SCP, for example using WinSCP. To connect over SCP, specify the IP address and enter the credentials of the CPE device.
Place the firmware archive in the /tmp directory.
Connect to the CPE device over SSH. To connect over SSH, specify the IP address and enter the credentials of the CPE device.
Change to the /tmp directory:
cd /tmp/
Update the firmware on the CPE device in one of the following ways:
- If you want to leave the CPE device settings unchanged after updating the firmware, run the following command:
  sysupgrade knaas-<firmware archive name>
- If you want to reset the CPE device to factory settings after updating the firmware, run the following command:
  sysupgrade -n knaas-cpe<firmware archive name>
When a CPE device is reset to factory settings, it is disconnected from the orchestrator. To reconnect the CPE device to the orchestrator, you need to automatically register (ZTP) the CPE device.

The new firmware version is installed on the CPE device, then the CPE device is restarted. By default, the IP address of the CPE device is unchanged, and DHCP is enabled on LAN ports.
