Installing The Multichannel Media Converter
The following sections explain how to install the unit onto your network. The unit can be
installed as a standalone system (such as on a desk) or in a standard 19-inch rack.
Selecting a Site for the Multichannel Media Converter
Be sure to observe the following requirements when choosing a site for your media converter:
•
Select a site that provides conditions (temperature and humidity) conforming to the
environmental requirements (see specifications below).
•
Select a site that is dust-free and moisture-free.
•
Do not block the ventilation openings on the unit. The site should allow for proper heat
dissipation from and adequate ventilation around the media converter.
•
Be sure that the site will allow you to easily access the twisted pair cables, fiber cables, and
power cord (s).
•
Use dedicated power circuits or power stabilizers to supply reliable power to the unit.
•
Keep the media converter and twisted pair cabling away from sources of electrical noise,
such as radios, electric motors, transmitters, broadband amplifiers, power lines, and flourescent
fixtures.
Planning the Installation
Refer to the following guidelines when planning the installation of the media converter:
•
All nodes connected to the ports on the media converter must operate at 10 Mbps.
•
The nodes connected to a same channel on the media converter must operate
with the same duplex mode, either half-duplex or full-duplex. For instance, you
cannot connect a node operating at half-duplex to a twisted pair port and another
node operating at full-duplex to the fiber optic port of the same channel on the
media converter.
•
Refer to table 2 for the twisted pair cabling specifications.

Use a straight-through cable to connect a hub or a switch to a twisted pair port on
the unit. Use a crossover cable to connect a workstation to a twisted pair port on
the unit.
