2 HARDWARE DESCRIPTION

Product Overview

The Converter is enhanced with Link Fault Signaling (LFS) and

Loopback Test (LBK) functions to offer the most comprehensive network status monitoring and connection diagnostics. It is designed for large workgroups who demand higher speed and wider bandwidth.

It allows migration and expansion from a copper-based Ethernet to a fiber optic Fast Ethernet.

It features automatic MDI detection setting. This function allows for simple direct connection to a workstation, switch or hub. Therefore, network managers no longer need to worry about cable type configuration when establishing a connection between RJ-45 ports.

This Converter is equipped with an RJ-45 port and a fiber optic ST or

SC or WDM port. This allows it to quickly integrate a 10/100Base-TX network into a 100Base-FX (fiber) network.

It features DIP switches for manual half or full duplex mode configuration on both copper and fiber ports. In full duplex mode, this Converter has the ability to support distances of up to

2 kilometers for multi-mode fiber and up to 60 kilometers for long-haul single mode fiber between a LAN switch, file server or another networking device.

DIP Switches

DIP 1 – Enables / disables auto-negotiation (RJ-45)

DIP 2 – Copper port (RJ-45) duplex mode: full or half-duplex

DIP 3 – Copper port (RJ-45) data bit rate: 10Mbps or 100Mbps

DIP 4 – Fiber port duplex mode: full duplex or half-duplex

DIP 5 – Enables / disables Link Fault Signaling (LFS)

DIP 6 – Enables / disables Local Loop Back (LLB)

DIP7 – Enables / disables Remote Loop Back (RLB)

Notes:

All models in this series feature the above set of DIP switches.

NWay DIP Switch Setting

Use the NWay DIP switch to activate NWay operations.

Factory NWay DIP switch default set to ON position. Check that the networking device to be connected to the Converter has NWay support.

If YES:

Check that the NWay DIP switch is set to the ON position. The

Converter will automatically set the optimum speed and duplex mode on the copper segment. Users can skip the settings for

DIP switches 2 and 3, when NWay is activated.

If NO :

Set the NWay DIP switch to the OFF position. Then Use DIP switch 2 to manually select between half (HD) and full duplex

(FD) modes. Use DIP switch 3 to manually select between

10Mbps or 100Mbps speeds. Set NWay switch to OFF position when connecting to an auto-sensing device that only supports

10/100Mbps detection. Some early switch models only support auto-sensing of speed, and NOT auto detection of speed and duplex mode (auto-negotiation).

Important

!

In order to configure DIP switches 2 (duplex mode) and

3 (speed), you must set DIP switch 1 (NWay) to the OFF position

NWay DIP Switch Setting continue

Setting the duplex mode is feasible while the media converter is "on-line"

Note:

If you experience the following problems, please check if the

NWay switch is properly set.

1. The LNK (link) LED is not lit and the connection cannot be established

2. The LNK LED is lit and the connection is ok, but cannot transmit or receive data

3. The converter functions properly for a while, then, it does not work. And then it works after powering off and then on again.

Link Fault Signaling (LFS)

LFS is a "nice to have" function that is extremely beneficial in terms of network status monitoring. The LFS LED will immediately light to indicate when a cable has been severed or when some other cause of disruption in service has occurred. The LFS function monitors both copper and fiber segments giving a total connection status report.

Set LFS to ON position for normal operational use.

Set LFS to OFF position when installing cables or when testing the network connection.

!

Note:

The LFS feature influences both fiber and copper segments.

Therefore, when disruption occurs on either segment, the LFS feature will be activated and the LED will light to indicate that the entire connection is down.

To appreciate the full benefits of LFS, four converters can be used to build a primary and a secondary link. They must be connected to a switch that supports Spanning Tree or Fast Spanning Tree protocols. By default, transmission of data will travel via the primary link. Once a fault has been detected, transmission will automatically be switched to the secondary link, resulting in ‘nonstop’ network connectivity.

Loopback Test

This Converter features DIP switches to activate both local and remote loopback diagnostic test functions. Use local loop back to check if the copper segment is connected properly, and use remote loop back to check if the fiber segment is connected properly.

Please see Diagram below:

Dip Switch 6 ON: enables local loop back function

OFF: disables local loop back function

Dip Switch 7 ON: enables remote loop back function

OFF: disables remote loop back function

Make sure that the cables are connected properly before getting started. Conduct either the local or remote test, not both at the same time. Follow the steps below to perform the diagnostic tests.

On a PC, use a program such as Sniffer to conduct the tests.

Other methods include the use of SmartBits series testing equipment. If you do not have access to either method, please contact your vendor for advice.

Install the converter

This Converter utilizes ports with fiber and copper port connectors functioning under Ethernet and/or Fast Ethernet protocols.

10/100BASE-TX Port

The 10/100BASE-TX port supports network speeds of either 10Mbps or 100Mbps, and can operate in half- and full duplex transfer modes. This port also offers automatic MDI/MDI-X crossover detection that gives true "plug and play" capability - just plug-in the network cable to the port and the port will adjust according to end node device automatically. The RJ-45 connector is suitable for

UTP cable Category 3, 4, 5 or better.

100BASE-FX Port

The 100BASE-FX port adds a fiber Fast Ethernet link to your network device. Compliant with IEEE 802.3u, this port can transmits data at 100Mbps in full duplex mode across distances of up to 2km over multi-mode fiber-optic cable. The fiber port has a choice of three fiber connector types: ST, SC and WDM.

Desktop Installation

Follow the instructions listed below to install the Converter onto a desktop location.

1. Locate the Converter in a clean, flat and safe position that has easy access to AC power.

2. Affix the four (4) self-adhesive rubber pads to the underside of the Converter.

3. Apply AC power to the Converter. (The green PWR LED on the front panel should light).

4. Connect cables from the network partner devices to the ports on the front panel. (The green LNK LED on the front panel associated with the port should light).

This Converter can also be mounted on a vertical surface. Simply use the underside of the unit as a template to measure and mark out the position of the holes on to the surface where the unit is to be installed. Then use two screws to mount the converter firmly in place.

!

Warning

Please exercise caution when using power tools. Also, install this unit away from damp or wet locations, or in close proximity to very hot surfaces. These types of environments can have a detrimental effect on the converter and cables. An ideal location is a lightly cooled place such as a typical equipment room.

Because invisible laser radiation may be emitted from the aperture of the port when no cable is connected, avoid exposure to laser radiation and do not stare into open apertures.

Getting Connected

Powering On Unit

The Converter uses an AC power supply 100~240V AC, 50~60 Hz.

The Converter's power supply automatically self-adjusts to the local power source and may be powered on without having any or all

LAN segment cables connected.

1. Insert the power cable plug directly into the receptacle located at the back of the device.

2. Plug the power adapter into an available socket.

Note:

For International use, you may need to change the AC power adapter cord. You must use a power cord set that has been approved for the receptacle type and electrical current in your country.

2. Check the power LED on the rear of the Converter

3. when the device is powered on to verify that power is applied.

If not, check that the power cable is correctly and securely plugged in.

Connecting Fiber Cable

When connecting fiber cable to a 100BASE-FX port on the

Converter, be sure the correct type - ST or SC or WDM - connector is used. Follow the steps below to properly connect fiber cable:

1. Remove and keep the ST/SC/WDM port's rubber cover. When not connected to a fiber cable, the rubber cover should be replaced to protect the optics.

2. Check that the fiber terminators are clean. You can clean the cable plugs by wiping them gently with a clean tissue or cotton ball moistened with a little ethanol. Dirty fiber terminators on fiber optic cables will impair the quality of the light transmitted through the cable and lead to degraded performance on the port.

3. Connect one end of the cable to the ST/SC/WDM port on the

Converter and the other end to the ST/SC/WDM port on the other device.

Note:

When inserting the cable, be sure the tab on the plug clicks into position to ensure that it is properly seated.

4. Use DIP switch 4 to select between half and full duplex modes for the fiber port

5. Check the corresponding port LED on the Converter to make sure that the connection is valid. (Refer to the LED chart in next section)

Connecting Copper Cable

The 10/100BASE-TX RJ-45 Ethernet port fully supports auto-sensing and auto-negotiation.

1. Insert one end of a Category 3/4/5/5e type twisted pair cable into an available RJ-45 port on the Converter and the other end into the port of the network node.

2. Check the corresponding port LED on the Converter to be sure that the connection is valid. (Refer to LED chart in next section)
