Check whether the DIN-Rail mounting kit thatStep 1comes with the device is installed firmly.Insert the bottom of DIN-Rail mounting kit (one sideStep 2with spring support) into DIN-Rail, and then insertthe top into DIN-Rail.Tips:Insert a little to the bottom, lift upward and then insertto the top.Check and confirm the product is firmly installed onStep 3DIN-Rail, and then mounting ends.【Disassembling DIN-Rail】Power off the device.Step 1After lift the device upward slightly, first shift out theStep 2top of DIN-Rail mounting kit, and then shift out thebottom of DIN-Rail, disassembling ends.Attention before powering on: Power ON operation: first connect power line to theconnection terminal of device power supply, and thenpower on. Power OFF operation: first unpin the power plug, andthen remove the power line, please note the operationorder above.【Power Supply Connection】 DC power supplyThis series provide redundant power input function and 2input terminal blocks of PWR1 and PWR2, which can be usedseparately or connected to 2 independentDC power supply systems. The devicecan be simultaneously connected to twopower supply systems via two terminalblocks, and it can run normally withoutinterruption when one of the power supply systems fails,improving the reliability of network operation.Power supply range: 24VDC (12~48VDC).【Relay Connection】The access terminal blocks of relay locate onthe top panel of the device. The terminal blocksare a pair of normally open contacts in the alarmrelay of the device. They are closed circuit in the status ofnormal no alarm, and open circuit when any warning messageoccurs. IES318 series support 1 relay warning messageoutput (this series only support power down alarm of the portlink and warning message output of customizable powersupply). It can be connected to alarm indicator, alarm buzzer,or other switching value collecting devices for timely warningoperating staffs when the warning message occurs.【DIP Switch Settings】This series provide 10 pins DIP switch forfunction settings, where "ON" is the enable validterminal.DIP switch definitions as follows:DIP Definition Operation1~8 Enabled alarm settingsswitch of the correspondingportSet the switch toON for enabling thealarm9 The alarm settings of thesecond power supplyON represents thestatus of alarm10 The alarm settings of thefirst power supplyON represents thestatus of alarm【Checking LED Indicator】The function of each LED is described in the table as below:LED Status DescriptionPWR1 ON PWR1 is connected and runningnormallyOFF PWR1 is disconnected andrunning abnormally.P2ON PWR2 is connected and runningnormallyOFF PWR2 is disconnected andrunning abnormallyALARMON Power supply and port link alarmOFF Power supply and port link withoutalarmRUN Blinking Blink once per second, the deviceis running well.OFF The device is running abnormally.LINK/ACT(1-8)ON Ethernet port connection is active.OFF Ethernet port connection isinactive.Blinking Data transmitted【Specification】Panel100M fiber port 100Base-FX, optional SC/ST/FCinterface100M copper port10 Base-T/100Base-TX, RJ45,automatic flow control,full/half duplex mode andMDI/MDI-X autotunningAlarm interface2 pins 7.62mm pitch terminalblocks, support 1 relay alarmoutput, and the current loadingcapacity is 1A@24VDC or0.5A@120VAC.IndicatorPower indicator, runningindicator, interface indicator andalarm indicatorExchange attributesBackplane bandwidth 1.6GPacket buffer size 1MbitMAC table size 2K
