Appendix D: Redundancy
January 2015
In addition to the redundancy diagnostics, an additional check may be configured to test
network connectivity to a host system or other application. The redundant system will use this
check to determine the best connectivity option and which Gateway should be set to the active
Gateway.
To configure network connectivity check:
1. Navigate to System Settings>Gateway>Ethernet Communication.
2. Enter the host system IP address in the Check Network Connectivity IP Address field.
3. Select Save Changes.

D.6 Gateway replacement
When replacing or reintroducing a Gateway in a redundant system, always connect both the
primary and secondary Ethernet connections before powering the standby Gateway. If the
Gateway is being reintroduced (i.e. it was a part of the original redundant system), it will
automatically rejoin the redundant system. If the Gateway is new or has been set to default
configuration, it will need to be paired to the current active Gateway. Navigate to System Set-
tings>Gateway>Redundancy and follow the recommended actions on that page or follow the
procedure above to pair Gateways and form a redundant system.
