Chapter 3: Installation

Confirm that the crossover switch is in the correct position.

 

before contacting the Cabletron Systems Global Call Center. Refer to 

 for details.

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

). Cabletron Systems offers optional fiber optic cables that use 

SC style connectors. These connectors are keyed to ensure proper cross 
over of the transmit and receive fibers. The FE-100FX is designed for use 
with multimode fiber, and the FE-100F3 is designed to use single mode 
fiber. Use of the incorrect fiber type may cause network problems. Please 
refer to the Cabletron Systems Cabling Guide for further information.

To connect a fiber optic segment, proceed as follows:

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

See 

 for more information describing how an 

FE-100TX module links to another 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.
