1. Plug the cable appropriate for use with your transceiver module into one of the Monitoring ports, for example, G1/1.
2. Plug the cable appropriate for use with your transceiver module into one of the Monitoring ports labeled G1/2.
3. Connect the other end of each cable to the tap.
4. Connect the network devices that you want to monitor to the tap.
:
Connect the cables for SPAN or hub mode
For the Sensor, monitoring in SPAN or hub mode occurs in in-line fail-open mode. When you monitor in SPAN or hub mode, you
use only single ports.
To connect an Sensor to a SPAN port or hub, plug an LC ber-optic or 45 cable into one of the modules and connect the other
end of the cable to the SPAN port or the hub.
:
Connect the cable for standalone Sensor failover
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 congure 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 congure 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 ber cables from external vendor.
