Cabletron Systems pmn manual Connecting a Fiber Optic Segment to the FE-100FX and FE-100F3

Connecting to the Network

b.Verify that the RJ45 connector on the twisted pair segment has the proper pinouts.

c.Check the cable for continuity.

d.Make sure that the twisted pair connection meets the cable specifications outlined in the Cabletron Systems Cabling Guide.

e.Confirm that the crossover switch is in the correct position.

If a link is not established, see Chapter 4, Troubleshooting, before contacting the Cabletron Systems Global Call Center (refer to Section 1.5 for details).

3.5.2Connecting a Fiber Optic Segment to the FE-100FX and FE-100F3

The FE-100FX and FE-100F3 have SC style network ports (see Figure 3-11).

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 crossing over occurs.

Fiber Optic Network Connection

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

The FE-100F3 uses 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.
