H801ETHB Board
This topic covers the working principle, application, front panel,
port, and specifications of the H801ETHB board.
Feature and Specifications
Ethernet Service Access Boards Comparison
Ethernet service access boards include H801ETHA and H801ETHB.
In the table, "Yes" indicates "supported" and "No" indicates "not
supported".
Table 1 Specifications of Ethernet service access boards

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.
Table 1 Power consumption and maximum frame size of boards
Board | Power Consumption | Maximum Frame Size |
Ethernet service access board |
H801ETHB | Static: 20 W Maximum: 21 W | 2052 bytes. After the jumbo frame function is enabled, a maximum of
9216 bytes can be supported. |
