H801SCUH Board

The H801SCUH board is a super control unit board. It is the core of the system control and service switching and aggregation. The H801SCUH board can also function as the management and control core of the integrated network management system (NMS). It communicates with service boards about the key management and control information through the master/slave serial port and inband 10GE/20GE channel. In this manner, the H801SCUH board configures, manages, and controls the device, and also implements the simple route protocol functions.

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.

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.
