Description |
Basic function |
1.This board is responsible for system control and management operations, including route calculation, device management and maintenance, and device monitoring. As a system synchronization unit, this board provides high-precise and reliable clock and time signals. 2.This board is responsible for cell transmission between LPUs and implements Ethernet communications with the SRU for centralized system control and management of the SRU. In addition, this board supports board temperature and voltage monitoring. |
Reliability and availability |
This board integrates the functions of the main processing unit and switching function. The 1:1 backup mode is used for MPUs.The 3+1 backup mode is used for SFUs. The four SFUs balance services at the same time. If one SFU is faulty or replaced, the other three SFUs automatically take over its services to prevent service interruptions. |
Restrictions and remarks |
This board cannot be installed in the same chassis as other types of main control boards. |
