Connecting to the Network6H123-50 and 6H133-37 User’s Guide3-93.5.3 Connecting a Fiber Optic Segment to theFE-100FX and FE-100F3The FE-100FX and FE-100F3 have an SC style network port (seeFigure 3-4). Cabletron Systems supplies fiber optic cable that uses SCstyle connectors that are keyed to ensure proper crossing over of thetransmit and receive fibers.Fiber Optic Network Connection1. Remove the protective plastic covers from the fiber optic ports on theapplicable port on the module and from the ends of the connectors.2. Insert one end of the SC connector into the FE-100FX or FE-100F3installed in the 6H123-50. See Figure 3-4.3. At the other end of the fiber optic cable, attach the SC connector to theother device.!CAUTIONAn odd number of crossovers (preferably one) must bemaintained between devices so that the transmit port of onedevice is connected to the receive port of the other device andvice versa.If the fiber optic cable being used has SC style connectors thatdo not resemble MIC style connectors, or has SC connectorson one end and a different type on the other, such as STconnectors, ensure that the proper crossing over occurs.!CAUTIONThe FE-100F3 uses Class 1 lasers. Do not use opticalinstruments to view the laser output. The use of opticalinstruments to view laser output increases eye hazard. Whenviewing the output optical port, remove power from the networkadapter.!CAUTIONDo not touch the ends of the fiber optic strands, and do not letthe ends come in contact with dust, dirt, or other contaminants.Contamination of the ends causes problems in datatransmissions. If the ends become contaminated, blow thesurfaces clean with a canned duster. A fiber port cleaning swabsaturated with optical-grade isopropyl alcohol may also be usedto clean the fiber optic ends.
