Connecting to the Network

An odd number of crossovers (preferably one) must be

!maintained between devices so that the transmit port of one

CAUTION

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.

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 SC connectors.

NOTE

Leave the protective rubber covers in place when the connectors are not in use to prevent contamination.

!

CAUTION

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.

2.Insert the SC connector at one end of the fiber optic cable into the port on the 2H28-08R. See Figure 3-6.

3.At the other end of the fiber optic cable, attach the SC connector to the other device.
