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.

Table 1 MPUs available for the CR16000-M routers

Module model

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

CAUTION:

For the standby MPU to start up correctly, make sure the active and standby MPUs are the same model.
