LED Indicators

The Compact Media Converter features four diagnostic LEDs. The diagram below shows the location of the LEDs.

The LED functions are:

FX RCV Glows yellow when the Converter is receiving data.

TX LNK Glows green when a twisted pair link is established.

FA Glows green when FiberAlert is enabled and blinks when a FiberAlert situation occurs (i.e. the loss of one strand of fiber).

NOTE

FiberAlert does not apply and does not function on single-strand fiber versions of the 100Mbps Compact Media Converter.

FX LNK Glows green when a fiber link is established.

Installing the 100 Mbps Compact Media Converter

While the 100 Mbps Compact Media Converter comes ready to install, all configuration changes should be made after installation. To install the Compact Media

Converter, make sure the unit is placed on a suitably flat surface. Then, attach the cables between the Compact Media Converter and each device that will be interconnected. Finally, plug the unit into a reliable, filtered power source.

NOTE

Since single-strand fiber products use optics that transmit and receive on two different wavelengths, deploy single-strand fiber products in pairs, or connect two compatible Black Box single-strand fiber products.

INSTALLATION TROUBLESHOOTING

To test the 100 Mbps Compact Media Converter during installation, first test the fiber and twisted pair connections with all troubleshooting features disabled, then enable these features, if desired, just before final installation. This will reduce the features’ interference with testing.

When working with units whose features cannot be disabled, both twisted pair and fiber cables must be connected before the link LEDs will light.

To test a media converter by itself, first verify that an appropriate fiber patch cable is being used. Then, follow these steps:

Step 1: Connect the media converter to the twisted pair device with a twisted pair cable.

Step 2: Loop a single strand of fiber from the transmit port to the receive port of your media converter.

Step 3: Verify that both twisted pair and fiber link LEDs light on the Compact Media Converter.

Use the appropriate twisted pair cable, and have the crossover/pass-through switch set correctly.

If using a high powered device designed for long distance installations in a short distance installation, an optical attenuator may be needed to prevent data loss on a connection.

Fiber Optic Cleaning Guidelines

Fiber optic equipment is extremely susceptible to contamination by particles of dirt or dust which can obstruct the optics and cause performance degradation.

Good system performance requires clean optics and connector ferrules.

1) Only use fiber patch cords (or connectors) from a reputable supplier; lowquality components can cause many hard-to-diagnose problems.

2) Black Box installs dust caps to ensure factory-clean optical devices. These protective caps should not be removed until the moment of connecting the fiber cable to the device. Assure that the fiber is properly terminated, polished and free of any dust or dirt and that the location is as free from dust and dirt as possible.

3) Store spare caps in a dust-free environment such as a sealed plastic bag or box so reinstalled caps do not introduce any contamination to the optics.

WARNING

Integrated circuits and fiber optic components are extremely susceptible to electrostatic discharge damage. Only qualified service technicians using tools and techniques comforming to accepted industry practices should handle these components.

4) Reinstall the protective caps when disconnecting the fiber device.

5) To clean contaminated optics, alternate between blasting with clean, dry, compressed air and flushing with methanol to remove particles of dirt.

What Is Pulsing FiberAlert?

Pulsing FiberAlert provides the same function as FiberAlert but, rather than ceasing transmission when the receiving unit goes down, Pulsing FiberAlert sends pulses through the line so that once the receiving unit starts to function, transmission commences. Use Pulsing FiberAlert in the following two situations:

A) When connecting two Compact Media Converter units (or connecting a

PSE-Compact Media Converter to a 100 Mbps Module TX/FX) with

FiberAlert enabled.

B) When connecting one Compact Media Converter with FiberAlert enabled and one 10/100 Autosensing unit with Link Fault Detection (LFD) enabled.

INSTALLATION TIP

Enable FiberAlert and/or Pulsing FiberAlert on only ONE side of a media conversion; enabling it on both sides will keep both transmitters off indefinitely.

Configuring the 100 Mbps Compact Media Converter

The 100 Mbps Compact Media Converter features an 8-position DIP switch for configuring the unit after installation. This switch is accessed through a cut-out in the bottom. After configuring the DIP switch, power cycle the

Compact Media Converter for the changes to take effect. Default settings for the following features are shown in the diagram.

• AN ENABLED (Auto-Negotiation)

• MDI/MDI-X (Manual port setting)

• AUTO MDI/MDI-X (AutoCross)

• TX LL (TX LinkLoss)

• FX LL (FX LinkLoss)

• FA ENABLED (FiberAlert)

• FA PULSE (Pulsing FiberAlert)

Some switches are reserved for future development.

Twisted Pair Crossover/Pass-Through Connections

Whether using crossover or straight-through CAT5 twisted pair cabling, the 100

Mbps Compact Media Converter will support both types of connections by one of the following methods:

AutoCross (Switch 4): The Compact Media Converter includes AutoCross, a feature which automatically selects between a crossover workstation or passthrough/ repeater hub connection depending on the connected device. To enable

AutoCross, move the Auto MDI/MDI-X switch to the ON position.

MDI/MDI-X (Switch 3): To manually configure the Compact Media Converter for a pass-through (MDI) or a crossover (MDI-X) connection, set Switch 4 to OFF and set Switch 3 to the desired connection type: MDI=OFF and MDI-X=ON. If unsure about the type of connection, set the DIP switch to a position that makes the twisted pair LNK (link) LED glow.

Auto-Negotiation

Auto-Negotiation, enabled by default, allows the Compact Media Converter to communicate at the speed and duplex settings of the device to which it is connected. Therefore, if the device connected to the Compact Media Converter sends and receives at 100Mbps, Full-Duplex, so will the Compact Media Converter. This will function within the operating parameters of the Compact Media Converter

(10/100Mbps, Half or Full Duplex).

To make the Compact Media Converter only communicate at one speed or one duplex setting, Auto-Negotiation will need to be turned off.

About FiberAlert and LinkLoss

The Compact Media Converter comes with the following troubleshooting features:

• FX LinkLoss (LinkLoss over a Fiber cable)

• TX LinkLoss (LinkLoss over a Twisted Pair cable)

• FiberAlert (including Pulsing FiberAlert)

LinkLoss and FiberAlert are advanced troubleshooting features that can help locate "silent failures" on a network. Users should understand how FiberAlert and

LinkLoss work, and how they will act in a network environment, before attempting to install the Compact Media Converter.

NOTE

Without understanding LinkLoss and FiberAlert, the 100 Mbps Compact Media

Converter could appear flawed or even malfunctioning.

About Link Integrity

During normal operation, link integrity pulses are transmitted by all point-topoint Ethernet devices. When a Compact Media Converter receives valid link pulses, it knows that the device to which it is connected is functioning, and that the copper or fiber cable coming from that device is intact. The appropriate “LINK” LED is lit to indicate this. The Compact Media Converter also sends out link pulses from its copper and fiber transmitters, but normally has no way of knowing whether the cable to the other device is intact and the link pulses are reaching the other end. FiberAlert and LinkLoss allow this information to be obtained from the fiber, even when physical access to a remote device (and its link integrity LED) is not available.

What Is FX LinkLoss?

FX LinkLoss is a troubleshooting feature that allows users to detect failures over the fiber connection. When a fault occurs on the fiber segment of a conversion, FX

LinkLoss detects the fault and passes this information to the twisted pair segment.

If a Compact Media Converter is not receiving a fiber link, FX LinkLoss disables the transmitter on the Compact Media Converter 's twisted pair port. This results in a loss of link on the device connected to the twisted pair port.

What Is TX LinkLoss?

TX LinkLoss is a troubleshooting feature that allows users to detect failures over the twisted-pair connection. When a fault occurs on the twisted pair segment of a conversion, TX LinkLoss detects the fault and passes this information to the fiber segment. If a Compact Media Converter is not receiving a twisted pair link,

TX LinkLoss disables the transmitter on the media converter's fiber port. This results in a loss of link on the device connected to the fiber port.

5

What is FiberAlert?

FiberAlert is a troubleshooting feature that minimizes the problems associated with the loss of one strand of fiber. If a strand is unavailable, the

Compact

Media Converter

notes the lost link and will stop transmitting data and the link signal until a signal or link pulse is received. The result is that the link LED on BOTH sides of the fiber connection will go out indicating a fault somewhere in the fiber loop. Using

FiberAlert, a local site administrator is notified of a fault and can quickly determine the location of a cable fault.

Using FiberAlert and LinkLoss

The following table provides an overview of the troubleshooting features, their functionality and the recommended settings for a pair of media converters in a typical central/main site to remote site application:
