H801SCUL Board
The H801SCUL board is a super control unit board. It mainly controls the system and processes broadband services. The H801SCUL board communicates with the service boards through the GE channel or the 10GE channel to configure, manage, and control the device. It also implements the simple route protocol functions. The H801SCUL board processes the alarms through the inband NMS. Based on the upper-layer protocol between the H801SCUL board and the service boards, the software of the H801SCUL separates the management information such as alarms from the information reported by the service boards. Then, the H801SCUL board identifies and processes the information.
Feature and Specifications
SCU Boards Comparison
All SCU boards support the functions as below:
System control and management unit
Active/standby switchover
Local and remote maintenance through maintenance serial port CON or maintenance Ethernet port ETH
Environmental monitoring through environment monitoring serial port ESC
In the table, "Yes" indicates "supported" and "No" indicates "not supported".

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
