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.
