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 the following table before you configure a HA pair:
Sensor Model | Port to connect the HA pair | Cable requirements for failover |
|---|---|---|
NS9500 | G0/1 | QSFP28/QSFP+ Direct Attach Copper (DAC) |
You can use 2-port QSFP28 interface module, or 2-port QSFP+ interface module or 4-port QSFP+ interface module for Sensor failover. Port G1/1 is used for failover. G1/2 is unusable. For 4-port interface module, ports G1/3 and G1/4 can be used as monitoring ports.
The system ships with a 1m QSFP28 DAC cable. This can be used for failover connection if the failover sensors are placed within 1m.
If you need to configure HA pair between sensors kept at distance greater than 1m, consider the following options:
For distances up to 3m, purchase QSFP28 DAC from Trellix.
For distances greater than 3m, purchase 40G QSFP transceivers from Trellix and fiber cables from external vendor.
Plug the cable(s) appropriate for use with your QSFP+ or QSFP28 module into port G0/1 (NS9500) of the active NS-series Sensor.
Connect the other end of the cable(s) into port G0/1 (NS9500) of the standby NS-series Sensor.
