Pin Function For Terminal Block:
External power supply is connected using the removable terminal block:
+Vs :
Power input (+10 ~ +30V) and should be connected to the power supply (+)
GND :
Ground and should be connected to the power supply (-)
F.G. :
F.G. stands for Frame Ground (protective ground). It is optional. If you use this
pin, it can reduce EMI radiation; improve EMI performance and ESD protection.
Checking Power:
Since the NS-205G consumes 4.8W max, ensure that your power supply is able to meet
this demand. The Input voltage range is +10~ +30VDC.
Power Savings by Number of Connected Ports and Link Status:
Computers do not require Internet access all the time; neither do switches utilize all ports
at all times. When a computer or network equipment is shutdown, switches often remain
on and continue to consume considerable amount of power. With Power saving
technology, NS-205G can automatically detect link status and reduce power usage of
ports that are idle. Computers or any connecting parties set to standby mode (not power
off), however, will not provide significant power savings.
Power Savings by Cable Length:
The powers saving switches have the ability to analyze the length of any Ethernet cable
connected to them for adjustment of power usage accordingly. Shorter lengths require less
power.
