The basic working principle of the H801SPUB 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 service processing module processes the MPLS packets and the service data packets,
and forwards the service data packets.
l The power module draws -48 V power from the backplane and converts the power into
working power for each functional module of the board.
l The clock module provides clock signals for each functional module of the board.
