Cabletron Systems 6E133-25 User Manual

Chapter 3: Installation

The FE-100FX and FE-100F3 have an SC style network port (see 

). Cabletron Systems supplies fiber optic cable that uses SC 

style connectors that are keyed to ensure proper crossing over of the 
transmit and receive fibers.

Remove the protective plastic covers from the fiber optic ports on the 
applicable port on the module and from the ends of the connectors.

Insert one end of the SC connector into the FE-100FX or FE-100F3 
installed in the 6E12X-26. See 

At the other end of the fiber optic cable, attach the SC connector to the 
other device.

An odd number of crossovers (preferably one) must be 
maintained between devices so that the transmit port of one 
device is connected to the receive port of the other device and 
vice versa.

If the fiber optic cable being used has SC style connectors that 
do not resemble MIC style connectors, or has SC connectors 
on one end and a different type on the other, such as ST 
connectors, ensure that the proper crossing over occurs. 

The FE-100F3 uses Class 1 lasers. Do not use optical 
instruments to view the laser output. The use of optical 
instruments to view laser output increases eye hazard. When 
viewing the output optical port, power must be removed from 
the network adapter.

Do not touch the ends of the fiber optic strands, and do not let 
the ends come in contact with dust, dirt, or other contaminants. 
Contamination of the ends causes problems in data 
transmissions. If the ends become contaminated, clean them 
with alcohol using a soft, clean, lint-free cloth.
