Restoring firmware of a KESR-M1 CPE device

You can restore the firmware and reset a KESR-M1 CPE device to factory settings if you have lost the credentials of that CPE or if you encounter a problem with the firmware.

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.

To restore the firmware of a KESR-M1 CPE device:

1. 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.
2. Extract the firmware archive to get the firmware in BIN format.
3. Power on the CPE device with factory firmware:
   1. Disconnect the power cable of the CPE device.
   2. Connect the power cable and press and hold the RESET button on the CPE device for 10 seconds.

   The CPE device powers on with the factory firmware.

4. Connect the administrator device to the LAN port of the CPE device.

   The administrator device gets an IP address and the IP address of the default gateway in the 192.168.1.0/24 subnet via DHCP.

5. In the address bar of the browser on the administrator device, enter 192.168.1.1 and press Enter.

   This opens the CPE device firmware upload page.

6. Click the firmware upload button and specify the path to the firmware in BIN format. You got the firmware in BIN format at step 2 of these instructions.

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 192.168.7.1, and DHCP is enabled on LAN ports.
