Connecting to the Network

2.4.1Connecting a Fiber Optic Segment to the FEPIM

DIGITAL offers fiber optic cables that use SC style connectors which are keyed to ensure proper crossover of the transmit and receive fibers.

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 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 instruments to view laser output increases eye hazard. When viewing the output optical port, power must be removed from the network adapter.
