Why use the CN.UPGRADE01 board?

We use this board to protect the safety of personnel and equipment as much as possible
during the upgrading. The main board should be connected to mains to work if we do not use
the CN.UPGRADE01 board. The power module of main board have more than thousands of

upgrading procedure. So we use the CN.UPGRADE01 board to reduce the risk of upgrading.
