For Sensor failover, connect two NS-series Sensors using the appropriate cables. These two Sensors must be running the same software version. Failover cables are the only additional hardware required to support failover communication between two NS-series Sensors.
Refer to the following table before you configure a failover pair:
Sensor Model | Port to connect the failover pair | Cable requirements for failover |
|---|---|---|
NS9300 | G1/1 and G1/2 | 2 40G QSFP Copper direct connect cable |
NS9200 | G0/1 | 1 40G QSFP Copper direct connect cable |
NS9100 | G0/1 | 1 40G QSFP Copper direct connect cable |
Trellix ships the cable required for failover pair creation, along with the Sensor hardware.
The length of this cable is 3 meters. If you need to configure a failover pair between Sensors kept at distance greater than 3 meters, consider the following options:
Failover between 3 meters - 100 meters: Purchase fiber Active Optical Cable (AOC) or QSFP+ SR4 transceiver module from Trellix or QSFP+ SR4 transceiver module from an external source.
Failover between 100 meters - 300 meters: Purchase QSFP+ SR4 transceivers from Trellix or QSFP+ SR4 transceiver from an external source.
Failover above 300 meters: Purchase QSFP+ LR4 transceivers from Trellix or QSFP+ LR4 transceivers from an external source.
Steps:
Plug the cable(s) appropriate for use with your QSFP+ module into port G0/1 (NS9100, NS9200) or G1/1 and G1/2 (NS9300) of the active NS-series Sensor.
Connect the other end of the cable(s) into port G0/1 (NS9100, NS9200) or G1/1 and G1/2 (NS9300) of the standby NS-series Sensor.
