An ISO (re-imaging) should be performed on every SBC received through Return Merchandise Authorization (RMA) process. To know more about re-installing ConnexIP OS, refer to:

During installation of the application, the local host role must be carefully entered. The local host role depends on what the system (being replaced) was originally configured for.  For example if it was originally the active system. So the local host role must be configured as active.

Check the Overall System Status

The system status can be checked by using EMA GUI or by CLI commands.

Using EMA GUI

For detailed information, refer to All - System.

Using CLI

The following commands must be executed to check the system status:

% show table system serverStatus
% show table system syncStatus 

For details, refer to the section show table system.

As part of the application install, the system will reboot. After reboot, the standby system starts to sync with the active system automatically. The sync process can take approximately 30 to 40 minutes. The sync and server status can be monitored through CLI/EMA/EMS on the active system.
