The H901MPSC board is a control board. It is the core of the system control and service switching and aggregation. The H901MPSC 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 channel. In this manner, the H901MPSC board configures, manages, and controls the device, and also implements the simple route protocol functions. Feature and Specifications Comparison Between Boards of the Same Type This topic describes differences on functions and specifications between boards of the same type. Control Boards Comparison All control boards support the functions as below: Active/standby switchover at the control panel Load sharing at the forwarding panel Local and remote maintenance through maintenance serial port CON or maintenance Ethernet port ETH Environmental monitoring through environment monitoring serial port ESC NOTE: For H901MPSC board, the maintenance serial port (CON) and environment monitoring serial port (ESC) sharing the same port. In the table, 'Yes' indicates 'supported' and 'No' indicates 'not supported'.
