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.
