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: MT-RJ, SC, and ST formats in Multi-mode and SC in Single
Mode. The UTP port suppor ts the Auto MDI/MDIX function and there are
4 DIP switches to set the operation mode for the UTP ports, Fiber ports,
the Link Loss Forwarding function, and the converter mode. These
converters can be used in Unicom’s 10 bay VELOCITY Media Chassis or
as stand-alone components.

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 features Auto­Sensing 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 100Base-FX connection. Unicom
provides three different styles of fiber connectors (MT-RJ/SC/ST,
Multi-Mode or SC, Single-mode).

FCC Statement

This equipment has been tested and found to comply with the limits for a class B
device, pursuant to part 15 of the FCC r ules. These limits are designed to provide
reasonable protection against harmful inter ference in a commercial installation.
This equipment generates, uses and can radiate radio frequency energy and, if not
installed and used in accordance with instructions, may cause harmful
interference with radio communications. Operation of this equipment in a
residential area is likely to cause harmful inter ference, in which case, the user will
be required to correct the inter ference at the user’s expense.

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 For warding 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.
Refer to page 10 for application diagram.

Rear Panel

The rear panel contains a power socket. This power socket accepts

DC 9V voltage and minimum 700mA supplied current.

Troubleshooting

• Verify that you are using the right power adapter ( DC 9V, 700mA ).
Using a power adapter with DC output greater than 9V 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.

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 RJ­45 connector on any 10/100Base-TX device.

B. Connect one end of a fiber jumper to the fiber connector on this

converter and the other end of the fiber jumper to the fiber
connector on the other 100Base-FX device.

C. Attach the power adapter DC jack to the conver ter. 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
Velocity 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.

C. Use a screwdriver to attach the rack mount ears to both sides of

the modular converter.

D. Install the modular converter by inser ting 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.).
