This procedure describes how to cable Sensors in a stack for high availability.
Plug the QSFP28 Direct Attach Copper (DAC) cable into port G0/3 of the first Sensor in the active stack.
Connect the other end of the cable into the corresponding port labeled G0/3 of the first Sensor in the standby stack.
Repeat steps 1 and 2 for the other Sensors in the active and standby stack.

On the rear panel of each NS9600 Sensor, plug a RJ-45 cable in the Management port (labeled MGMT).
Plug the other end of the cable into the network device connected to your Manager server.
Create a failover pair using the HA Pairs tab in Devices → <Admin Domain Name> → Global → Device Manager page in the Manager.
