FIBER OPTIC CONVERTERS
4.1 Controls and Indicators
All of the Fiber Optic Converter’s controls and indicators, except for the
power switch, are located on the Converter’s front panel, shown in
Figure 4-1 below. The power switch is located on the rear panel of the unit,
immediately above the power-cord connector (see
Section 3.4
).
The Converter’s complete model number is on the right side of the front
panel. Below the model number is a fastening screw (see
Section 3.3
).
The table below lists the functions of these controls and indicators. The
numbers under the
Item
