LED Indicator Functions:
| LED | Color | Description |
| Ethernet Port | Green On | Link to 10/100/1000 Mbps |
| Yellow On | Act | |
| PWR1 | Green On | This green LED is turned on when power is applied to the PWR1 input |
| PWR2 | Yellow On | This yellow LED is turned on when power is applied to the PWR2 input |
| Fault | Red On | Any of the alarm enabled Port have been loss link. |
Pin Function for Terminal Block:
| Pin | Function | Description |
| 1 | PWR1 | Power1 input +12~+48VDC (V+) |
| 2 | P.GND | Power Ground. |
| 3 | RL_COM | Power Fault relay COM |
| 4 | RL_NO | Power Fault relay NO |
| 5 | PWR2 | Power2 input +12~+48VDC (V+) |
| 6 | P.GND | Power Ground. |
Redundant Power Input:
Both power inputs can be connected simultaneously to live DC power sources. If one power source fails, the other live source will act as a backup, and automatically supplies all of NSM-316G power needs.
External power supply is connected using the removable terminal block:
PWR (Power) : Power input (+12 ~ +48 VDC) and should be connected to the power supply (+)
GND: Ground and should be connected to the power supply (-)
Accessories(option):
| DR-120-48 | 48 V/2.5 A, 120 W Single Output Industrial DIN Rail Power Supply |
| MDR-60-48 | 48 V/1.25 A, 60 W Single Output Industrial DIN Rail Power Supply |
| DR-120-24 | 24V/5 A, 120 W Single Output Industrial DIN Rail Power Supply |
| SDR-240-24 | 24 V/10 A, 240 W Single Output Industrial DIN Rail Power Supply with PFC Function |
DIP Switch Settings:
| DIP Switch | Setting | Description |
| Port Alarm Function (P1 to P16) | ON | Enables the PORT Alarm. When the port’s loss link, the relay will forced an close circuit, and the fault LED will light up. |
| OFF | Disable the PORT Alarm. When the port’s loss link, there will no action from the relay, and it remain in open circuit, and the fault LED will not light up. |
Console Port:
A RS-232 with RJ45 connecter, for debugging, monitoring and setting, the baud rate of this port is 9600,n,8,1.
Accessories(option):
| CA-090510 | 9-pin Female D-sub & RJ-45 cable,1M |
