Overview
An MPU provides the following functions:
· Route calculation and forwarding table maintenance.
· System configuration and monitoring. It can monitor, upgrade, and reset the service modules.
· Active/standby switchover.
The following MPUs are available for the CR16000-M routers.

Description |
SR07MPUA3-M |
H3C CR16000-M main processing unit |
Key features
High performance routing engine
The MPUs employ domestic high performance multi-CPUs to provide powerful routing processing capability and powerful message processing capability for protocol messages and control messages.
Flexible configuration and compatibility
You can install one or two MPUs for the router. When two MPUs are installed, the router supports active/standby MPU switchover.
Hot swapping
You can install an MPU when the router is operating. When two MPUs are installed, you can remove one of them, without interrupting the interface module services. The management system performs real-time monitoring on the MPUs and automatically adapts to the changed configuration upon detection of the change, ensuring service continuity.
Specifications
CAUTION: For the standby MPU to start up correctly, make sure the active and standby MPUs are the same model. |
