Huawei PISA Power Module is DC power adapter board for MA5800 X2 OLT
Huawei PISA Power Module Product Overview
Huawei PISA Power Module is a power adapter board, which is used to introduce 2-way -48V / -60V DC power. The input power passes through the protection circuit and filter circuit and is output to the backplane to supply power to other boards in the service frame.
The H901PISA board supports the following features and specifications:
Two -48 V DC power input
Filtering and current-limiting for the power input port
Power input detection and protection fuse fault detection
Reporting of the protection alarm and board online signal
