In the unlikely event that you should need to replace an AIM Manager, whether it is a Solo, Primary, Backup or Satellite, this will guide you through the process. If you are replacing the 1st generation ALIF-AIM, please see the Migration guide.
Replacing a Solo AIM
It is advisable that you have more than one AIM Manager. For small installations, a solo AIM may be sufficient, however, it would not offer redundancy in the event of a failure. As of firmware version 3.3 and above, SSL/TLS certification was employed to secure the communication between the AIM Manager and endpoints (transmitters and receivers). For the endpoints to work with a replacement AIM Manager, a factory reset would be required to re-establish a new trust.
Procedure
- Boot up and configure the replacement AIM Manager (see Quick Start Guide)
- Restore a recent backup of the AIM.
- Factory Reset all the endpoints to recreate the SSL/TLS certificates. The endpoints will retain their configuration on the AIM after the reset.
Replacing a Primary AIM (requires an operational Backup Manager)
It is not possible to directly replace the Primary AIM Manager, you must promote the Backup Manager to be a Primary and then use the replacement AIM as a Backup. This is required to maintain the SSL/TLS trust between the AIM and endpoints. The replacement AIM will take the next available IP address after the promoted Primary. If you are using Infinity in a multi-subnet environment, your DHCP option 125 will need to be updated,
Procedure
- Promote the Backup AIM to be a Primary. Open the Backup AIM's web interface.
- Click on configure this server.
- Change the Role from Backup to Primary.
- Press Save to commit the change.
- Add the replacement AIM Manager as a Backup. See Adding Backup and Satellite AIM's.
Important
Replacing a Backup AIM
Replacing a Backup AIM is the same as adding one, with the exception that you should remove the original unit from the Primary's Server table.
Procedure
- Remove the original Backup AIM from the Primary Server table. Navigate to the Servers tab and delete the Backup Server.
- Add the replacement AIM Manager. See Adding Backup and Satellite AIM's.
Swapping over AIM Managers.
In a scenario where you wish to exchange your operating Primary Manager with another, for example, you are changing a 2nd gen for a 3rd gen, make sure that all of your endpoints are online before proceeding. You will need to first add the replacement unit as a backup AIM, shutdown the Primary and then promote the Backup to a Primary, Any units that are offline during this procedure will need to be manually factory reset.
