Connecting a Multimode Segment to the
FE-100FX
The FE-100FX has an SC style network port. 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.
Fiber Optic Network Connection
1. Remove the protective plastic covers from the fiber optic ports
on the applicable port on the module and from the ends of the
connectors.
2. Insert one end of the SC connector into the FE-100FX installed
in the ELS10-26.
3. At the other end of the fiber optic cable, attach the SC
connector to the other device.
4. Verify that a Link exists by checking that the port LINK LED is
on solid green. If the LINK LED is off, perform the following
steps until it is on:
a. Check that the cable is properly connected at both ends.
b. Check that the power is turned on for the device at the other
end of the Link.
c. Verify proper crossing over of fiber strands between the
applicable port on the ELS10-26 and the fiber optic device
at the other end of the fiber optic link segment.
d. Verify that the fiber connection meets the dB loss
specifications.
If a Link has not been established, contact Cabletron Systems
Global Call Center. Refer to the
Getting Help section in this guide
for details.
.
Caution: 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.
Caution: 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 errors in
data transmissions. If the ends become contaminated, clean
them with alcohol using a soft, clean, lint-free cloth.
