TP-Fiber (Multi-mode / Single-mode)
IEEE802.3 Ethernet Converter
1. Overview
IEEE802.3 10Mbps Ethernet supports various type media for network connection such as
10Base-2, 10Base-T and 10Base-FL. The media converter is used to convert one type
media signal to other type equivalent that allows multiple type segments connect easily and
inexpensively. This converter can be used as a standalone unit or as a slide-in module to the
19" Media Chassis (up to 10 units) for use at a central wiring closet.

5. Installing the Converter
For as a standalone unit:
⇒ Verify the Ac to DC adapter conforms to your country
AC power requirement and insert the power plug
⇒ Connect the media cable for network connection
For as a slide-in unit:
⇒ The slide-in Media Converter and Converter Rack should be supplied only from
the same source, both Media Converter and Rack are built to match each other at
dimensions, DC jack, DC receptacle and power safety
⇒ Turn off the 19" converter rack power
⇒ Locate +5VDC power jack on converter back, carefully slide in and plug to 19"
rack +5VDC power receptacle
⇒ Ensure that there is no activity in the network
⇒ Connect the media cable for network connection
⇒ Turn on the converter rack power, the Power LED will light up
