5.2.3 Deployment of Two Devices for High Availability
The device supports 1+1 high availability, whereby two devices are deployed and connected
to the same broadcast domain/s. In such a setup, the same Ethernet port-pair redundancy
setup is done for each device. For example, if port-pair 5 and 6 are used for Device "A", then
Device "B" must also use port-pair 5 and 6, as shown in the figure below:
Figure 5-5: Cabling for High Availability (Example)
In High Availability, the two devices interconnect through their Maintenance interfaces, using
the same Ethernet Port Group.
Note: For possible connections (including Tx / Rx settings) between the HA devices, refer
to the User's Manual.
