Correlate the pictures with the information following it to understand the components of an NS-series Sensor.

Console port (1)
RJ-11 port (1) for fail-open control of two built-in SFP+ ports in G0. This port is used only for passive fail-open mode.
SFP+ 1/10 Gigabit Ethernet ports (2). These ports support 1 Gbps (SFP) copper or fiber and 10 Gbps (SFP+) (SR and LR).
Two slots for I/O modules (Any combination of the interface modules can be used)
Note
The supported interface modules need to be purchased separately.
8-port SFP/SFP+ 1/10 Gigabit interface module
4-port 1/10 Gigabit fiber interface module with built-in fail open
6-port RJ45 10/100/1000 Mbps Ethernet interface module with built-in fail open
4-port RJ45 100/1000/10000 Mbps Ethernet interface module with built-in fail open
Built-in RJ45 10/100/1000 Mbps Ethernet Monitoring ports (8) with internal fail-open
The supported transceiver modules are SFP+ (MM and SM), SFP Fiber (MM and SM) and SFP Copper.

Power supply A/B (Pwr A/Pwr B)
USB ports (2)
RJ-45 1000/10000 Management port (Mgmt) (1)
RJ-45 1000/10000 Response port (R1) (1)
