10/100BASE-TX to 100BASE-FX Media Converter

2. Overview

2.1 Introduction

LBMC300-MMST and LBMC300-MMSC converters provide one channel for media conversion between 10BASE-T/100BASE-TX and 100BASE-FX. They can be used as a standalone device or with a standard 19” chassis as shown in Figure 2-1.

An LBMC300-MMST or LBMC300-MMSC media converter provides one TX port and one FX port. For the FX port, you can use multimode fiber cable with an SC or

ST connector, depending on the model. The TX port uses one RJ-45 connector and autosenses the 10-/100-Mbps speed.

Port settings are easy via a DIP (Dual Inline Package) switch on the rear panel of the module.

Figure 2-1. Converters installed in a rack.

NOTE: The rack (part number LB300A-RACK) is available separately.

2.2 Features

• Converts one channel between 10BASE-T/100BASE-TX and 100BASE-FX media

• Fiber media can be multimode fiber using SC or ST connectors

• Autonegotiation of speed and duplex mode on TX port

• Auto MDI-X on TX port

• One DIP switch for configuring link-fault-passthrough, fixed speed, and half/full duplex

• 2048 MAC addresses, 768K bits buffer memory

• Store-and-forward mechanism

To set the DIP switches:

1. First, disconnect the converter from the power. Then toggle Pin 2 of the DIP switch to the up position to enable the forced mode for TX port.

NOTE: Pin 2 must be toggled up before setting speed and duplex mode manually.

2. Toggle down Pin 3 to force the TX port at the speed of 100 Mbps. Or toggle up

Pin 3 for 10-Mbps speed.

3. Toggle down Pin 4 to force the TX port at full-duplex mode. Or toggle up Pin 4 for half-duplex mode.

4. Toggle down Pin 5 to force the FX port at full-duplex mode. Or toggle up Pin 5 for half duplex mode.

5. Toggle up Pin 1 to disable the link-fault-pass-through.

6. Connect the converter to the power again. The new setting will then take effect.

5. Link-Fault-Passthrough

Connect the FX ports of Media Converters A and B through the fiber cable.

1. Link Fault on the FX port of Media Converter A: A Link Fault condition will be sensed on the TX port whenever Media Converter A detects a Link Fault condition on the FX port. Thus, the 100, LNK/ACT, and FDX/COL LEDs of the TX port of Media Converter A would be off.

2. Link Fault on the TX port of Media Converter A: A Link Fault condition will be sensed on the FX port whenever the media converter detects a Link Fault condition on the TX port. Thus, the 100, LNK/ACT, and FDX/COL LEDs of the TX port of Media Converter A would be off.

The Media Converter B: A Link Fault condition will be sent to the FX port of

Media Converter B. Then a Link Fault condition will be sensed on the TX port of

Media Converter B whenever Media Converter B detects a Link Fault condition on the FX port. Thus, the 100, LNK/ACT, and FDX/COL LEDs of Media Converter B would be off.

Chapter 6: Installation

6. Installation

This chapter gives step-by-step installation instructions for the converter.

6.1 Selecting a Site for the Equipment

As with any electric device, you should place the equipment where it will not be subjected to extreme temperatures, humidity, or electromagnetic interference.

Specifically, the site you select should meet the following requirements:

• The ambient temperature should be between 32 and 113 degrees Fahrenheit (0 to

45 degrees Celsius).

• The relative humidity should be less than 95 percent, noncondensing.

• Surrounding electrical devices should not exceed the electromagnetic field (RFC) standards for IEC 8013, Level 2 (3V/M) field strength.

• Make sure that the equipment receives adequate ventilation. Do not block the ventilation holes on each side of the equipment.

• The power outlet should be within 6 feet (1.8 m) of the converter.

6.2 Connecting to Power

This Converter is a plug-and-play device.

Connect the supplied AC to DC power adapter to the receptacle on the rear panel of the converter, and then attach the plug into a standard AC outlet.

6.3 Installing in a Chassis

LBMC300-MMST and LBMC300-MMSC fit into any of the expansion slots on the compatible chassis, LB300A-RACK. Follow the steps described below.

First, install the converter onto a carrier supplied with the chassis:

Step 1: Unscrew the carrier from the desired expansion slot on the chassis.

Step 2: Fit the converter onto the carrier.

Step 3: When the converter is completely seated onto the carrier, insert the carrier to the guide rails of the expansion slot.

Step 4: Carefully slide in the carrier until it is fully and firmly fit in the chassis. Fasten the screws onto the carrier.

NOTE: Never insert any converter into the chassis directly without using the supplied carriers. The carriers enable you to place the converters securely and consistently without damaging them.
