5.1.3nnecting an EPIM-100FX or EPIM-100FMB

The EPIM-100FX and EPIM-100FMB have an SC style network port (see Figure 5-3). Cabletron Systems supplies fiber optic cables that use 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 EPIM-100FX or EPIM-100FMB:

1.Remove the protective plastic covers from the fiber optic ports on the module port and from the ends of the connectors.

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.

CAUTION	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 SEH EPIM-100FX or EPIM-100FMB. See Figure 5-3.

3.At the other end of the fiber optic cable, attach the SC connector to the other device.
