Huawei PRTE Power Transfer Board H801PRTE for huawei ma5600 ma5800 ma5608t

 H801PRTE Board

The H801PRTE is a connect power board. It leads in the -48 V DC power supply for the device.

Feature and Specifications

The H801PRTE board supports the following functions:

One -48 V power input

Filtering and current-limiting for the power input port

Under-voltage detection, detection of whether the input power exists, and fault detection

Combined reporting of the protection alarm and board online signal

ALARM indicator

Parameters

Power Consumption and Maximum Frame Size of Boards

You can query power consumption, maximum frame size, and normal operating temperature of all boards.

 lists the power consumption and maximum frame size of boards. "-" indicates N/A.

The operating temperature of all the boards is -40°C to +65°C. The lowest board startup temperature is -25°C.

 NOTE:

The power consumption of the board is tested in the following conditions:

Working voltage: -53.5 V DC.

Ambient temperature: 25 °C.

Static power consumption: All ports do not carry any loads. Specifically, users under POTS ports hang up phones, xDSL ports are deactivated, and optical modules are not installed on optical ports

Maximum power consumption: All ports fully carry loads. However, only 25% users under POTS ports concurrently pick up phones and the feeding current is 20 mA.

The board power consumption slightly varies with the power module configured for the board and discreteness of components.

Working Principle

Figure 1 Working principle of the H801PRTE board 

The basic working principle of the H801PRTE board is as follows:

The H801PRTE board has a 3V3 power connector to lead a channel of -48 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.

The detection and report circuit detects fault of the protection fuse. The detected signals and the presence signals of the board are reported to the control board through the same channel. The LED displays the status.

The detection and report circuit detects under-voltage of the input power and whether there is input power.

The E2PROM circuit stores the vendor information of the board.

The 5 V power led from the backplane is used to supply some chips of the board.
