Introduction
Congratulations on purchasing a quality UNICOM product.
Unicom’s VELOCITY Series represents the newest, most advanced
generation of signal conversion technology.
This converter is designed to expand your network through a fiber optic
connection extending a fiber link up to 60 km (Single mode in full duplex
mode).
The 10/100TX/100FX Converters offer the most popular fiber cabling
connectors: SC and ST formats in Multi-mode and SC in Single Mode.
The UTP port supports the Auto MDI/MDIX function and there are 4 DIP
switches to set the operation mode for the UTP, Fiber ports and Link
Loss Forwarding function. These converters can be used in Unicom’s 10
bay media chassis or as stand-alone components.
Key Features

■One fiber connector (SC/Single Mode, SC or ST/Multi-Mode) for
100Base-FX.
■Prevents packet loss by supporting back-pressure & flow control.
■Four DIP-switches for operation mode setup and Link-Loss
Forwarding function.
■Per port LEDs for diagnosis and maintenance
■External DC power adapter, 5V/2.5A

Troubleshooting
• Verify that you are using the right power adapter ( DC 5V, 2.5 A ).
Using a power adapter with DC output greater than 5V could result
in damage to the unit and/or personal injury.
• Check the configuration DIP switch. It must be set in the same
operation mode as its link partner.
• Confirm the proper UTP/Fiber cable is being used. The Single Mode
converter must use Single Mode fiber optic cable.
Hardware Description
The Front Panel
The Front Panel of the 10/100TX/100FX converters consists of one
RJ-45 Port ( Auto MDI/MDIX ), 6 LED Indicators (TX SPD, LK/ACT,
FDX/COL, Fiber LK/ACT, FDX and PWR ) and one fiber 100Base-FX
Port.
Ports
• RJ-45 Port (Auto MDI/MDIX): the Ethernet RJ-45 will features Auto-
Sensing for 10Base-T or 100Base-TX connections and Auto
MDI/MDIX which is basically an auto crossover feature. This
means you can connect to another Switch or workstation without
changing to a crossover cable.
• Fiber Port: This port is for the 100 Base-FX connection. Unicom
provides three different styles of fiber connectors (SC/ST, Multi-
Mode or SC, Single-mode).

C. Use a screwdriver to attach the rack mount ears to both sides of
the modular converter.
D. Install the modular converter by inserting it into the chassis
guides and sliding it in until it stops. Press it firmly to seat the
chassis power plug into the modular converter receptacle.
E. Gently push the thumbscrews in and turn clockwise to tighten.
Do not over tighten.
Cabling
• Twisted-pair segments can be Unshielded Twisted Pair (UTP) or
Shielded Twisted Pair (STP) cabling. The cable must comply with the
IEEE 802.3u 100Base-TX standard for Category 5e. The cable
between the converter and the link partner (switch, hub,
workstation, etc.) must be 100 meters (328 ft.) or less in length.
• Fiber segments using Single Mode connectors must use 8/125 or
9/125 µm Single Mode fiber cable. The maximum link distance is
15, 30, or 60 Kilometers (depending on model) in full duplex
operation. For half-duplex operation, the recommended maximum
distance is 412 meters (1352 ft.).
• Fiber segments using Multi-Mode connectors must use 50 or
62.5/125 µm Multi-Mode fiber cable. The maximum link distance is
2 Kilometers (6562 ft.).

LED Indicators
There are six diagnostic LEDs located on the Front panel of these
Converters. The LEDs provide real-time information on system sta-
tus. The indicators include Power, UTP 100, LK/ACT, FDX/COL, Fiber
LK/ACT, and FDX/COL. The following table provides descriptions of
the LEDs.
LED Status Color Description
PWR On Green • The converter is supplied with
suitable power.
100 On Green • Current UTP Speed
LK/ACT On Green • Unit is connected with a link
( UTP ) Blinking - • Unit is transmitting data
Off - • No device attached
LK/ACT On Green • Unit is connected with a link
( Fiber ) Blinking - • Unit is transmitting data
Off - • No device attached
FDX/COL On Orange • The UTP port is in full-duplex mode.
( UTP ) Blinking - • Packet Collisions occurring in the port.
Off - • Half-duplex mode/no device attached
FDX/COL On Orange • The fiber port is in full-duplex mode.
( Fiber ) Blinking - • Packet Collisions occurring in the port.
Off - • Half-duplex mode/no device attached

Network Connection
A. Select the appropriate length Category 5e or 6 twisted pair cable.
Connect one end of the twisted pair cable to the RJ-45 connector
on the converter and the other end of twisted pair cable to the RJ-
45 connector on any 10/100 Base-TX device.
B. Connect one end of a fiber jumper to the SC connector on this
converter and the other end of the fiber jumper to the SC
connector on the other 100 Base-FX device.
C. Attach the power adapter DC jack to the converter. Verify that the
Power LED is on.
D. Verify that the UTP “LK/ACT” LEDs light when cable connection is
installed correctly. Verify that Fiber “LK/ACT” LED blinks to indicate
network activity.
Installing Converters into Chassis
Follow the steps below to install modular converters into the 10 space
Converter Chassis (pn: FEP-593110).
A. Remove the blank bracket from the chassis by rotating
thumbscrew counterclockwise. Put the blank bracket aside.
B. Open the rack mount bracket kit. The kit contains two rack mount
brackets and four screws.
DIP Switch
The DIP-switches are used to configure operation mode for LLF ( Link
Loss Forwarding ) and operation modes for the UTP/Fiber ports.
DIP-switch setup is as follows:
Note: To activate DIP switch 4, DIP 3 must be enabled.
Link Loss Forwarding: The Link Loss Forwarding feature sends fiber
or UTP link failure information to the switches. Any failure along the
signal link is passed to and can be seen by an attached device. This
feature is used for easy network diagnosis and supports switches
utilizing Spanning Tree Protocol.
Note: Do not change the DIP-switch setting while the UTP or fiber
ports are transmitting or receiving data as data error may occur.
Rear Panel
The rear panel contains a power socket. This power socket accepts
DC 5V voltage and minimum 2.5A supplied current.
