NOTE: If you for some reason reboot the secondary module via the GUI, the primary module
will not take over as active module. However, if the secondary module is not up and
running again after 3 minutes, the primary module will become active.
On the secondary module, do as follows:
1 Click “Configuration” on the start page.
2 Select Other > Redundancy on the Configuration page.
3 Click the "Fallback to primary module" button.
NOTE: It is only possible to press the button if the data has been synchronized with
the primary module.
The primary module will now act as a active module and the secondary module will act as a
standby module.
4.12.6 Deactivate Redundancy
NOTE: This setting can only be performed on the primary module.
1 Click “Configuration” on the start page.
2 Select Other > Redundancy on the Configuration page.
3 Click the "Deactivate" button. Both modules will now reboot immediately.
4 Do one of the following:
• If you temporarily deactivated the redundancy to be able to upgrade the modules’
software, just use the modules’ current
1
IP-addresses to access them.
• If the IP-address was changed in the modules: Change the IP-address in the
former primary Unite CM to its origin IP-address. NOTE: If DCHP server is used, ask
your network administrator to reserve the IP-address to the module’s MAC
address.
• If the IP-address was changed in the equipment with configured Unite IP-address,
change to the origin IP-address.
IMPORTANT: Do not remove the SD memory card since it also will be used as storage
when the redundancy has been deactivated.
4.13 Backup the Configuration
The complete configuration for the current software on the module is included in the
backup. Files that have been added or changed on the ftp-area are also included in the
backup.
The backup file is saved in a proprietary file format and cannot be edited. Save it in a place
where you can easily find it for a restore.
1 Click “Configuration” on the start page.
2 Select Other > Backup/Restore on the Configuration page.
3 Click the “Backup” button.
4 Click the “Save” button in the opened dialogue.
