display the configured speed of the port).

2.6.3 Connecting a Multimode Segment to the FE-100FX
The FE-100FX has an SC style network port (see Figure 2-8).
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.
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.
