Cabletron Systems 2E43-51 User Manual

Chapter 3: Installation

The FE-100FX and FE-100F3 have SC style network ports. See 

. Cabletron Systems offers optional fiber optic cables that use 

SC style connectors. The ST connectors are keyed to ensure proper 
crossover 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 2E43-51. See 

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, blow the 
surfaces with a canned duster. A fiber port cleaning swap 
saturated with optical-grade isopropyl alcohol may also be used 
to clean the fiber optic ends.
