Firmware upgrade - How to make a firmware upgrade of 2N Access Unit?

When updating from version lower than 2.15.2, please stick to the following update steps:

Your version -> 2.15.2 -> 2.17.1 -> 2.18.1 -> 2.31.1 -> automatic update to the latest version (will be described later in this manual).

If you are updating from version higher than 2.15.2, continue with the next higher version according to the procedure above up to the latest version.
