Helpful resources to help you configure your Ecessa Edge in a hardware failover (high availability) setting.
Hardware Failover allows a second unit to function in an idle role and act as a backup device in the event of failure or loss of connectivity on the active unit. This is particularly useful in environments where any level of failure is unacceptable. This feature is also referred to as “high availability” or HA. The two units are connected by a cable for heartbeat communication and should be given the same physical network connectivity so failover is automatic.
