Chapter 5: Connecting to the Network
5-4 SEHI100TX User’s Guide
5.1.3 Connecting a Fiber Segment to the EPIM-100FX
The EPIM-100FX has an SC style network port (see Figure 5-3).
Cabletron Systems supplies fiber optic cables using SC connectors that
are keyed to insure proper crossover of the transmit and receive fibers.
Use the following steps to connect a fiber segment to the SEHI:
1. Remove the protective plastic covers from the fiber optic ports on the
module port and from the ends of the connectors.
2. Insert one end of the SC connector into the EPIM-100FX on the SEHI.
See Figure 5-3.

NOTE
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.
!
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 problems in data
transmissions. If the ends become contaminated, clean them
with alcohol using a soft, clean, lint free cloth.
