Working Principle
Figure 3-45 Working principle of the H801PRTE board
The basic working principle of the H801PRTE board is as follows:
l The H801PRTE board has a 3V3 power connector to lead a channel of -48 V or -60 V
power supply. After passing the protection circuit and the filtering circuit, the power
supply is output to the backplane and supplies power for other boards in the subrack.
