Updating Applications for the Standby MPU
When the router is configured with two MPUs, you need to ensure that the main application files for the
active and standby MPUs are of the same version. Otherwise, the standby MPU cannot normally start up.
As a result, the active and standby MPUs cannot back up each other and file operations; hence high
reliability of the device cannot be ensured.
You can update the version of the main application file of the standby MPU to that of the active MPU
through one of the following methods. Before updating the main application file for the standby MPU,
make sure that the main application file is stored in the CF card of the active MPU, or you should
download the main application file to the active MPU. For details, refer to procedures mentioned above.
