Working Principle
The basic working principle of the H801MPWC board is as follows:- The H801MPWC board leads in one -48 V power input through one 3V3 power connector, and transfers the power to the filter circuit, then to the current limit protection circuit, and finally to the backplane, supplying power to the subrack and other boards.
- The detection and reporting circuit checks the protection fuse for any faults, and reports the detection signals together with the board ready status signal to the control board. The control board indicates these detection signals through indicators.
- The detection and reporting circuit checks for input undervoltage and availability of power supply.
- The E2PROM circuit stores the board manufacture information.
- The H801MPWC board leads in the 5 V/3.3 V power from the backplane to power certain internal chips of the board.
