• Heartbeat Port: The Standby server periodically checks the availability of the Active server through this
port. The value of this port is 255 and is fixed.
Heartbeat Parameters
• Heartbeat Retry Count: The Standby server checks the availability of the Active server using Heartbeat
requests. The number configured as the Heartbeat Retry Count, defines the number of attempts that
need to be made by the Standby server to check the availability of the Active server. When no response is
received from the Active server and the count expires, the Standby server becomes Active. The Heartbeat
Retry Count may be set from 3 to 9. Default: 3.
• Heartbeat Interval (msec): This is the time interval after which the Standby server retries to fetch
Heartbeat response from the Active server. Valid Range is 100 to 1000 millisecond. Default: 300
millisecond.
• Make sure that Backup Server-Redundancy LAN IP address is same as Redundancy LAN IP
address of Backup Server.

Redundancy LAN IP address is same as Redundancy LAN IP address of Primary Server.
• When you submit the page after configuring, the system will restart to activate redundancy.
