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

| Maximum: 2.5 W | |||
| Indicates the channel of monitor signal | Indicates the channel of alarm signal | ||
| -48 V DC power | Protection circuit: protects the components in the circuit | ||
| Filter circuit: filters the DC power in the circuit | |||
| Detection circuit: checks the protection fuse for any faults and detects power input and the board ready status. It reports the detected results to the control board through the backplane | |||
| DC power | E2PROM circuit: stores the vendor information of the board | ||
| PWR0 | Running status indicator | Green: on | The input voltage and the protection fuse are normal. |
| Orange: on | The input voltage is normal but the protection fuse is faulty. | ||
| Off | There is no power input or the input voltage is lower than 34 V. | ||
| PWR1 | Running status indicator | Green: on | The input voltage and the protection fuse are normal. |
| Orange: on | The input voltage is normal but the protection fuse is faulty. | ||
| Off | There is no power input or the input voltage is lower than 34 V. |
