| Description | Switch and Route Processing Unit A22(SRUA-480-J, 32G Memory) |
| Part Number | 03050LFG |
| Model | ME0D0SRUAH7P |
| Card type | SRU |
| Silkscreen | SRUA-480-J |
| Functions and Features | Description |
|---|---|
| Basic function |
1. It is responsible for system control and management, including route calculation, device management and maintenance, and device monitoring. It also functions as the system synchronization unit to provide high-precision and high-reliability synchronization clock and time signals. 2. Switches cells between BSUs/MSUs, communicates with the main control boards over Ethernet, is subject to centralized control and management of the main control boards, and monitors the board temperature and voltage. |
| Reliability and availability |
Hot swapping is supported. The system control and switching fabric functions are integrated. The system control units work in 1:1 backup mode, and the switching fabric units work in 3+1 backup mode. The four SFUs load-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. This improves system reliability. |
| Restrictions and remarks | This board cannot be installed in the same chassis as other types of main control boards. |
| Breakout supported | No |
| Interface rate auto-sensing supported | No |
