1. NS 205G 5 Port Industrial 10 100 1000 Mbps Ethernet Switch Introduction The NS 205G is 5 port unmanaged gigabit switches that support 10 100 1000 Base T with a 10 100 1000M auto negotiation feature and auto MDI MDIX function It can connect 5 workstations and automatically switches the transmission speed 10 Mbps or 100 Mbps or 1000Mbps for corresponding connections That is an ideal solution for bandwidth hungry applications such as high resolution digital image transmission video audio file streaming downloading and server farm connectivity The flow control mechanism is also negotiated There is link data rate LEDs for each port to aid trouble shooting Port connectors are shielded RJ 45 Features e Power saving Technology e Automatic MDI MDI X crossover for plug and play e Each port supports both 10 100 and 1000 Mbps speed auto negotiation e Store and forward architecture e Full duplex IEEE 802 3x and half duplex backpressure flow control e 10 Gbps high performance memory bandwidth e Supports operating temperatures from 30 70 C e DIN Rail Specifications Technology Standards Processing Type MAC Addresses Memory Bandwidth Frame buffer memory Jumbo Frames Flow Control Interface RJ45 ports LED Indicators Ethernet Isolation Frame Ground for EMS Protection Power Input Voltage Range Power consumption Protection Frame Ground for EMS Protection Connection Mechanical Case Flammabi2. lity Dimensions Installation Environmental Operating Temperature Storage Temperature Ambient Relative Humidity IEEE 802 3 802 3u 802 3ab and 802 3x Store amp forward wire speed switching no delays 8K 10 Gbps 1 Mbit 9K for Speed 1000M IEEE802 3x flow control back pressure flow control 10 100 1000 Base T auto negotiation speed F H duplex mode and auto MDI MDIX connection Power 10 100 1000M Link Act 1500 Vrms 1 minute Yes 10 30VDC Non isolation 0 2A 24VDC 5 arrowed with 1000M Full duplex Power reverse polarity protection Yes 3 Pin Removable Terminal Block Plastic UL 94V 0 33mm x 107mm x 78mm W x H x D DIN rail mount 30 70 C 40 75 C 10 to 90 non condensing NS 205G User s Manual Version 1 0 May 2008 1 Dimensions __ LED functions nanan I Red On Power is On Power 99 0 ora i Red Off Power is Off a Orange On Link to 1000 Mbps DiI _ Ethernet Green On Port Only Orange On Link to 100 Mbps Only Green On Link to 10 Mbps LUL Hu _ S 1 mi l 150 L E 330 Left Side View Front View Right Side View Pin Function For Terminal Block External power supply is connected using the removable terminal block Vs Power input 10 to 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
3. 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 An automatic power savings when a specific An intelligent algorithm that actively determines the port is in link down or standby operation appropriate power level needed based on cable length up 60 up 10 Power Saving by Cable Length Power Cable Length NS 205G User s Manual Version 1 0 May 2008 2
