H901MPSCE Board Description

The H901MPSCE board is a control board. It is the core of the system control and service switching and aggregation. The H901MPSCE board can also function as the management and control core of the integrated network management system (NMS). It exchanges the key management and control information with service boards through the master/slave serial port and in-band channel. In this manner, the H901MPSCE board configures, manages, and controls the device, and also provides simple dynamic routing.

Indicates the control signal channel.



Indicates the service signal channel.



Control module: manages the entire board and the service boards, and communicates with the fan tray through the extended serial port.



  • Service processing module:

    • Providing 4 upstream GE/10GE ports.

    • Providing 4 10GE ports for load balancing with the standby control board.

  • Switching module: switches services at Layer 2 or Layer 3, and provides 2 40G channels for switching traffic to service boards or the upstream board.

  • Digital parameters detection module: detects the statue of the digital parameters of the environment monitor device.

  • The BITS clock module: recovers the 2 Mbit/s clock signals or shapes the 2 MHz clock signals, which can function as the system clock source.



Indicates the power or clock signal channel.



  • The power module supplies power to each functional module of the board.

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