2.4.1Connecting 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.
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.
1.Remove the protective covers from the fiber optic ports and from the ends of the connectors.
Leave the protective covers in place when the connectors are
TIP not in use to prevent contamination.
Certain FEPIMs use Class 1 lasers. Do not use optical
!instruments to view the laser output. The use of optical
CAUTION | 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 |
| to clean the ends. |
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.
