The basic working principle of the H802SHGM board is as follows:
l The control module loads the board software, controls the running of the board, and
manages the entire board.
l The protection module protects and isolates the board from lightning strikes. The DC
block isolates the direct current. The protector protects the high voltage.
l The forwarding module processes the signals. After being processed by the control
module, the signals are transmitted to the backplane bus through the interface of the
backplane.
l The interface module inputs, outputs, and converts the signals.
l The power module supplies power to each functional module of the board.
l The clock module provides clock signals for each functional module of the board.
