Unpacking and Installing Your ELS10-26

d.Make sure that the twisted pair connection meets dB loss and cable specifications.

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

f.Confirm that the devices on each end of the link are using the correct speed (use the LCM status command to check actual operating speed and use the speed command to display the configured speed of the port).

If a Link is not established, contact Cabletron Systems Global Call Center. Refer to Section 1.2, Getting Help, for details.

2.6.3 Connecting a Multimode Segment to the FE-100FX

The FE-100FX has an SC style network port (see Figure 2-8). Cabletron Systems supplies fiber optic cable that uses SC style connectors that are keyed to ensure proper crossing over of the transmit and receive fibers.

Caution: 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.

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 plastic covers from the fiber optic ports on the applicable port on the module and from the ends of the connectors.
