H802SCUN Board
The H802SCUN board is a super control unit board. It is the core of the system control and service switching and aggregation. The H802SCUN 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 GE/10GE channel. In this manner, the H802SCUN 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".
Table 1 Major differences between SCU boards
Board | Access Service | Daughter Board | Load sharing | Ethernet synchronization | Temperature querying and high temperature alarming | Built-in 2GB CF card | Centric Management for GE Remote Extended Subracks | D-CMTS |
H802SCUN | Optical and copper | H801FLBA H801CKMC H801CKMD H801M2XA (version B) | Yes (supported in V800R011C00 and later versions) | No | Yes | No | Yes | No |
NOTE:
H801SCUN and H802SCUN are slot compatible.

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.
