Cabletron Systems FOMIM-32 Manual De Usuario

This chapter lists the installation checkout procedures necessary to verify 
that the segments connected to your FOMIM are operating properly. The 
chapter concludes with a description of the LANVIEW LEDs and their 
use in troubleshooting physical layer network problems.

This section contains procedures to test the following:

•

The fiber optic link segment to be attached to the FOMIM

•

The link between the FOMIM and the device attached to the other end 
of the fiber optic link segment

•

The FOMIM itself

Test the segment being attached to the FOMIM to verify that the cable 
meets the fiber budget specifications discussed in Appendix A. Using a 
fiber optic power meter set, test the link segment as follows:

1. Attach a fiber optic jumper to the optical power meter. The meter 

should be set at 1300 nm.

2. Attach a fiber optic jumper to the optical source unit. If the source unit 

has multiple settings, it should be set at 1300 nm.

3. Using a barrel connector, connect the jumpers together.

4. Following the instructions for the test set, test the jumpers to get a 

reference level. Make a note of this reading.

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 can cause problems in data 
transmissions. If the ends become contaminated, clean them 
with denatured alcohol using a soft, clean, lint free cloth.
