8. Q & A

8.1. Do they have the same IP when configuration?

8.1.1. When configuring - configure the same. Redundancy will handle the configuration and IP address swapping - making 2nd 1+ current.

8.2. Can redundancy be used during a download?

8.2.1. No! Can't do download changes.

8.3. Remote IO go into fault during switchover?

8.3.1. No!

8.4. Can switchover trigger SMTP?

8.4.1. Can monitor trigger to alarm or do anything you want. KB article is in list
