5.1.3 nnecting 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.
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.
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.
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.
