Huawei MPLA Control Board H903MPLA
H902MPLA Board Description
The H902MPLA board is a control board. It is the core of the system control and service switching and aggregation. The H902MPLA 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 H902MPLA board configures, manages, and controls the device, and also implements the simple route protocol functions.

Indicates the channel of control signal. | Indicates the channel of service signal. | ||
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 four GE/10GE ports for upstream transmission using ports on the front panel. Providing four 10GE ports for load sharing with the standby control board. Switching module: switches services at Layer 2 or Layer 3, and provides 17 50G channels for implementing service switching on each service board or upstream board. | ||
Indicates the channel of power or clock signal. | 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. |
Front Panel Port
For details about supported optical module, see 10GE Optical Module and GE Optical/Electrical Module.
NOTE:
Default transmission rate of the upstream port or cascade port is 10000 Mbit/s (10GE), which can be set to 1000 Mbit/s (GE) by running the speed command.
Daughter Board
The H902MPLA board can be configured with a matching daughter board. Figure 2 shows the position of the daughter board on the H902MPLA board.
For details about the daughter board and functions supports by the H902MPLA board, see Daughter Board.
