Chapter 3: Installation3-142E43-51/2E43-51R User’s Guide3.5.3 Connecting a Fiber Optic Segment to theFE-100FX and FE-100F3The FE-100FX and FE-100F3 have SC style network ports. SeeFigure 3-11. Cabletron Systems offers optional fiber optic cables that useSC style connectors. The ST connectors are keyed to ensure propercrossover of the transmit 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 2E43-51. See Figure 3-11.NOTESAn 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, power must be removed fromthe network adapter.!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 with a canned duster. A fiber port cleaning swapsaturated with optical-grade isopropyl alcohol may also be usedto clean the fiber optic ends.
