Product Introduction

The H801SCUB board is a Super Control Unit Board. It is the core of the system control and service switching and aggregation. It can also function as the management and control core of the network management system (NMS). The H801SCUB board communicates with service boards about the key management and control information through the master/slave serial port and inband GE channel. In this way, the H801SCUB configures, manages, and controls the device. The H801SCUB also implements the simple route protocol function.

Overview 

The H801SCUB board supports the following functions: 

• System control and management unit 

• Local and remote maintenance 

• Active/standby switchover 

• GE channel to the service board 

• Environmental monitoring parameters 

• Four SFP GE ports for upstream transmission or cascading

Working principle of the H801SCUB board :

The basic working principle of the H801SCUB board is as follows: 

• The control module manages the H801SCUB board and service boards, and communicates with the fan tray through the extended serial port. 

• The power module supplies power to other functional modules of the board. 

• The clock module provides clock signals for other functional modules of the board. 

• The switching module provides the GE port to switch and aggregate services at Layer 2 or Layer 3.

– Providing 16 GE ports to implement GE switching on each service board 

– Providing four GE ports for upstream transmission using the control board or upstream board (in the first of the two slots for the upstream board), which is controlled by the electronic switch. 

– Providing four GE ports for upstream transmission using the upstream board (in the second of the two slots for the upstream board). Either the last GE port or VoIP daughter board can be used for upstream transmission, which is controlled by the electronic switch.

Port

The ports of the H801SCUB board are located on the front panel of the board.
