Miniature in size, it offers plug-and-play operation, and supports an extended voltage range as well as extended operating temperature.. The media converter can function as a PD device, and is compliant to the IEEE 802.3af Power Over Ethernet (PoE) standard. Available in a variety of Single Mode and Multi Mode fiber types, it supports an MTU of 1916 bytes. Several mounting options and powering options are available and detailed in the following sections of the manual.HARDWARE INSTALLATION -BOTH PRODUCT LINES The IE-MiniMc installs virtually anywhere as a standalone device in locations with extremely limited space. Installation options include:·Velcro strips·DIN rail mounting with DIN Rail clips· A wall mount bracket· A PowerTray/18 for high density applicationsHARDWARE MOUNTING OPTIONSThe IE-MiniMc can be mounted on a DIN rail or using wall mount brackets (shown below).Figure 1. Wall Mount BracketDIN rail clips (part number 806-39105) and wall mount brackets (part number 895-39229) are available for purchase through an B&B Electronics Distributor. The DIN Rail clips include screws, to allow the installation onto a DIN Rail. Install the screws into DIN Rail clips, which should be mounted parallel or perpendicular to the DIN Rail. Snap the converter onto the clips. To remove the converter from the DIN Rail, use a flat-head screwdriver into the slot to gently pry the converter from the rail.Figure 2. DIN Rail MountingPOWERING OPTIONSThe IE-MiniMc includes multiple powering options:· A country-specific, high-reliability AC power adapter (included)·The IEEE 802.3af Power over Ethernet standard; draws power from power sourcing equipment (NON-Telco version only)·The 4-terminal DC power block·IE-PowerTray/18 for Rack MountingPower Over EthernetPower Over Ethernet technology allows the IE-MiniMc to be a Powered Draw device (PD) and draw power when connected to Power Sourcing Equipment (PSE). Power Sourcing Equipment distributes an electrical current across existing copper data cabling.LEDSEach IE-MiniMc includes two LEDs, located on the RJ-45 connector.LED functions are as follows:FXLNK/ACT Glows green when a link is established on the fiber port; blinks green when activity is detected on the fiber port.TXLNK/ACT Glows amber when a link is established on the copper port; blinks amber when activity is detected on the copper port.Table 1. LEDSDC TERMINAL BLOCK WIRING INSTRUCTIONSThe IE-MiniMc can also be powered with the DC terminal block. From a power source, connect to any one positive and any one negative terminal on the IE-MiniMcFigure 3. DC Terminal BlockNOTEWhen using stranded wire, the leads must be tinned and equivalent to a 16 AWG solid conductor. The DC terminal block is protected against mis-wiring. If the unit is mis-wired, positive power lead to the negative terminal and negative power lead to the positive terminal, it will not function. When powering a unit with voltages near the upper limit of the device’s specification (for example: 50 volts) take precautions to limit the voltage at the units terminal block. When turning on high voltage DC circuits, initial voltages may exceed the maximum allowed duration of the unit’s transient protection devices.Cascading DC PowerWhen installing multiple IE-MiniMc units on a DIN rail, the end user can connect to one DC input source, and then cascade from one DC block to the next, until reaching the maximum current available.SPECIFICATIONSConnectorsCopper RJ-45Fiber ST, SCEnvironmental -- Intended for indoor and outdoor use.Operating Temperature -40°F to +185°F (-40°C to +85°C) DC configuration +14°F to +122°F (-10°C to +50°C) with AC wall adapterStorage Temperature-40°F to +185°F (-40°C to +85°C)Operating Humidity 5 to 95% (non-condensing); 0 to 10,000 ft. altitude LED Indicators One Green LEDCopper RJ-45 port LNK/ACT Color = GREENBlink = GREEN when data is passing Off = NO COLORFiber Port LNK/ACT Color = AMBERBlink = AMBER when data is passing Off = NO COLORPower InputDC Terminal Block 7 to 50 VDC, 1-0.1ADC jack 5 to 24 VDCPoE When IE-MiniMc uses PoE technology to be a PD,the maximum supply voltage is 50VTable 2.

CertificationsELECTROSTATIC DISCHARGE PRECAUTIONS Electrostatic discharge (ESD) can cause damage to any product, add-in modules or stand-alone units, containing electronic components. Always observe the following precautions when installing or handling these kinds of products:Do not remove unit from its protective packaging until ready to install. Wear an ESD wrist grounding strap before handling any module or component. If the wrist strap is not available, maintain grounded contact with the system unit throughout any procedure requiring ESD protection. Hold the units by the edges; do not touch the electronic components or gold connectors.After removal, always place the boards on a grounded, static-free surface, ESD pad or in a proper ESD bag. Do not slide the modules orstand-alone units over any surface. WARNING! Integrated circuits and fiber optic components are extremely susceptible to electrostatic dischargedamage. Do not handle these components directly unless you are a qualified service technician and use tools andtechniques that conform to accepted industry practices.FIBER OPTIC CLEANING GUIDELINESFiber optic transmitters and receivers are extremely susceptible to contamination by particles of dirt or dust, which can obstruct the optic path and cause performance degradation. Good system performance requires clean optics and connector ferrules.Use fiber patch cords (or connectors, if you terminate your own fiber) only from a reputable supplier; low-quality components can cause many hard-to-diagnose problems in an installation.Dust caps are installed at B+B SmartWorx to ensure factory-clean optical devices. These protective caps should not be removed until the moment of connecting the fiber cable to the device. Should it be necessary to disconnect the fiber device, reinstall the protective dust caps.Store spare caps in a dust-free environment such as a sealed plastic bag or box so that when reinstalled they do not introduce any contamination to the optics.If you suspect that the optics have been contaminated, alternate between blasting with clean, dry, compressed air and flushing with methanol to remove particles of dirt.CERTIFICATIONSCE: The products described herein comply with the Council Directive on Electromagnetic Compatibility (2004/108/EC). For further details, contact B+B SmartWorx.European Directive 2002/96/EC (WEEE) requires that any equipment that bears this symbol on product or packaging must not be disposed of with unsorted municipal waste.
