Chapter 5: Connecting to the Network

5.1.3Connecting 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.

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.

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.

C AUT IO N

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.

2.Insert one end of the SC connector into the EPIM-100FX on the SEHI. See Figure 5-3.
