OPERATION

This section describes the operation of the Black Box Media Converters

including power supply requirements, up-link switch functionality, and a description of

all LEDs.

4.1

Power Requirements, Power Supply Types

Black Box Media Converters require 6 watts of power and are designed to be

used with an external power supply.

The external power supply unit supplied is one of

two types; one version (U.S. and Canadian models) for AC input power of 115 vac 60

Hz, and one international version for 230 vac 50 Hz. The 115 vac version has a small

transformer integral with a convenience power outlet plug. The 230 vac version has a

small transformer integral with an IEC-type power plug for a user-supplied AC power

cord with a convenience power outlet plug. Both types include a lightweight DC power

cord to the applicable power jack on the Media Converter unit.
