Huawei PISA Two -48V DC Power Board H901PISA

H901PISA Board 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.
