2.4.1 Connecting a Fiber Optic Segment to the FEPIM
Cabletron Systems offers fiber optic cables that use SC style connectors
which are keyed to ensure proper crossover of the transmit and receive
fibers.
1. Remove the protective covers from the fiber optic ports and from the
ends of the connectors.
2. Insert one end of the SC connector into the FEPIM.
3. At the other end of the fiber optic cable, attach the SC connector to the
other device.
NOTES
An odd number of crossovers (preferably one) must be
maintained between like 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 crossover occurs.
TIP
Leave the protective covers in place when the connectors are
not in use to prevent contamination.
!
CAUTION
Certain FEPIMs use Class 1 lasers. Do not use optical
instruments to view the laser output. The use of optical
instruments to view laser output increases eye hazard. When
viewing the output optical port, power must be removed from
the network adapter.
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, blow the
surfaces clean with a canned duster. A fiber port cleaning swab
saturated with optical-grade isopropyl alcohol may also be used
to clean the ends.
