Huawei PISA DC 03023WED H901PISA Power Transfer Board for MA5800 series
Product Description:
The H901PISA board is a power transfer board. It leads in 2 channels of -48 V DC power, and transfers the power to the protection circuit, then to the filter circuit, and finally to the backplane, supplying power to other boards in the service subrack.
Feature and Specifications:
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
Parameters:
Board Parameter
You can query power consumption, weight, maximum frame size, and normal operating temperature of all boards.
Table 1 lists the power consumption, weight, and maximum frame size of boards.
The operating temperature of H901XSED and H901TWED is -40°C to +55°C (in MA5800–X17/X15/X7) or -40°C to +65°C (in MA5800–X2) and the lowest board startup temperature is -25°C. The operating temperature of other boards is -40°C to +65°C and the lowest board startup temperature is -25°C.
NOTE:
The power consumption of a board is calculated based on the following conditions:
Operating voltage: -53.5 V DC.
Ambient temperature: 25°C.
Static power consumption: All ports do not carry any loads and optical modules are not installed on optical ports.
Maximum power consumption: All ports fully carry loads.
The board power consumption slightly varies with the power module configured for the board and discreteness of components.
