Fast Ethernet Media Converter

FCC COMPLIANCE STATEMENT
This equipment generates and uses radio frequency energy and if
not installed and used properly, that is, in strict accordance with
the instructions provided with the equipment, may cause
interference to radio and TV reception. The equipment has been
tested and found to comply with the limits for a Class A
computing device in accordance with the specifications in Subpart
B of Part 15 of FCC rules, which are designed to provide
reasonable protection against such interference in a commercial
environment. However, there is no guarantee that interference will
not occur in a particular installation.
If you suspect this equipment is causing interference, turn your
converter on and off while your radio or TV is showing
interference to determine the source of the interference.
You can try to correct the interference by one or more of the
following measures:
1. Reorient the receiving radio or TV antenna where this may be
done safely.
2. To the extent possible, relocate the radio, TV or the other
receiver away from the equipment.
3. Plug the computer which has the equipment installed into a
different power outlet so that equipment and the receiver are on
different branch circuits.
If necessary, you should consult the place of purchase or an
experienced radio/television technician for additional suggestion.
CAUTION : The phone jack cannot be connected to telephone
system.

1.Introduction
Congratulations on your purchase of this product. This is a Fast
Ethernet standard compliant media converter. This media converter
allows users to convert the Fast Ethernet transmission media from
UTP to fiber or fiber to UTP.
This media converter comes with two 100BaseTX twisted pair ports
and a 100BaseFX fiber optic port. The UTP ports have two RJ-45
connectors and a maximum distance of 100 meters. The fiber optic
port has an ST, SC or MT-RJ connector and a maximum distance of
2Km (Multi-Mode Fiber) to 60km (Single-Mode Fiber).
Fast Ethernet media converter’s operation mode (Half-/Full-Duplex)
is solely depending on the Fast Ethernet devices connected to. Users
do not have to configure it.

5.Installation
(1) Operating Environment
This converter must be installed and operated within the limits
of specified operating temperature and humidity (see previous
section under Specifications). Do not place objects on top of the
unit. Do not position the converter near any heating source such as
heater, radiator, or direct exposure to sun. Prevent entering of water
and moisture into the unit. If necessary, use dehumidifier to reduce
humidity.
(2) Guidelines for installation
Please observe following guidelines when you are installing the
media converter.
# The nodes connected to the media converter must operate at
100Mbps.
# The two nodes connected to the ports of the media converter
must operate with the same duplex mode.
# The devices connected to the media converter can be
network adapter, hubs, switches or routers.
# The network configuration with media converter could be
any one of the following architectures.

(3) Connecting the cable
Make sure the UTP and fiber cables are properly connected to
the converter. Using the normal category 5 UTP straight-through
cable for connecting the UTP normal port to PC/adapter or
connecting the UTP uplink port to hub port. Using 50/125 or
62.5/125 micron multi-mode fiber to connect to the fiber port of
multi-mode media converter. Using 9/125 micron single-mode fiber
to connect to the single-mode media converter.
(4) Connecting the power
Connect the output end of the power adapter to the power
connector on the rear panel of the converter. Connect the power
adapter to the power outlet. The green Power LED on the front panel
of the hub should be lit.

6.Trouble-shooting
1. UTP or Fiber Link LED is not lit
! Check the power switch on the network device connected to the
converter, make sure it is turned ON.
! Check the network cable; make sure the UTP cable complies with
EIA/TIA 568 specification and fiber optic cables comply with
industry standards.
2. Fail to transmit data
! Make sure the UTP distance does not exceed 100m.
! If the FDX LED does not light (not operates in full-duplex mode),
make sure the fiber distance does not exceed the maximum distance
listed below. If the FDX LED lights, the fiber distance should not
exceed the available maximum distance of the converter, for
example 2km or 60Km.
