WISTED P AIR C ROSSOVER/PASS-THROUGH

C ONNECTIONS

Whether you are using crossover or straight-through CAT5 twisted pair cabling, Compact Media Converter will support both types of connections by one of the following methods:

AutoCross Switch 4: Compact Media converter includes AutoCross, a fea- ture 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 Compact Media Converter for a pass-through (MDI) or a crossover (MDI-X) connection, move the Auto MDI/MDI-X Switch 4

to OFF, then move Switch 3 to the desired connection type: MDI=OFF and MDI-X=ON. If you are unsure of the type of connection, set the DIP switch to a position that makes the twisted pair LNK (link) LED glow.

About FiberAlert and LinkLoss

Compact Media Converter comes with the following troubleshooting features:

• FX LinkLoss (a.k.a. "Fiber LinkLoss" or "LinkLoss")

• TX LinkLoss (a.k.a. "Twisted Pair LinkLoss” or "Reverse LinkLoss”)

• FiberAlert (including Pulsing FiberAlert)

LinkLoss and FiberAlert are advanced troubleshooting features that can help you locate "silent failures" on your network. However, it is vital that you understand exactly how FiberAlert and LinkLoss work, and how they will react in your network configuration, before attempting to install the enclosed module(s).

Installing modules without understanding the effects of LinkLoss and FiberAlert can cause perfectly functioning units to appear flawed or even dead.

If you are unfamiliar with LinkLoss and FiberAlert, Black Box strongly encourages you to read the following information. Contact Black Box technical support for more information/assistance.

F IBER O PTIC C LEANING G UIDELINES

Fiber Optic transmitters and receivers are extremely susceptible to contamination by particles of dirt or dust, which can obstruct the optic path and cause performance degradation. Good system performance requires clean optics and connector ferrules.

1) Use fiber patch cords (or connectors, if you terminate your own fiber) only from a reputable supplier; low-quality components can cause many hard-to-diagnose problems in an installation.

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 that when reinstalled they do not introduce any contamination to the optics.

4) Should it be necessary to disconnect the fiber device, reinstall the protective dust caps.

5) If you suspect that the optics have been contaminated, alternate between blasting with clean, dry, compressed air and flushing with methanol to remove particles of dirt.

E LECTROSTATIC D ISCHARGE P RECAUTIONS

Electrostatic discharge (ESD) can cause damage to your add-in modules. Always observe the

following precautions when installing or handling an add-in module or any board assembly.

1) Do not remove unit from its protective packaging until you’re ready to install it.

2) Wear an ESD wrist grounding strap before handling any module or component. If you do not have a wrist strap, maintain grounded contact with the system unit throughout any procedure requiring ESD protection.

WARNING! Integrated circuits and fiber optic components are extremely susceptible to electrostatic discharge damage. Do not handle these components directly unless you are a qualified service technician and use tools and techniques that conform to

accepted industry practices.

3) Hold boards by the edges only; do not touch the electronic components or gold connectors.

4) After removal, always place the boards on a grounded, static-free surface, ESD pad or in a proper ESD bag. Do not slide the board over any surface.

A BOUT L INK I NTEGRITY

During normal operation, link integrity pulses are transmitted by all point-topoint Ethernet devices. When an Black Box media converter receives valid link pulses, it knows that the device to which it is connected is up and sending pulses, and that the copper or fiber cable coming from that device is intact. The appropriate “LINK” LED is lit to indicate this. The Black Box 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. (See below for explanation of features, see page 4 for using the features in a typical application).

W HAT I S FX LINKL OSS?

FX LinkLoss is a troubleshooting feature. 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 media converter is not receiving a fiber link, FX LinkLoss disables the transmitter on the media converter's twisted pair port. This results in a loss of link on the device connected to the twisted pair port.

W HAT I S TX LINKL OSS?

TX LinkLoss is another troubleshooting feature. 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 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.

W HAT

I S F IBERALERT

FiberAlert minimizes the problems associated with the loss of one strand of fiber. If a strand is unavailable, the Black Box device at the receiver end notes the loss of link. The device will then 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 where a cable fault is located.

Installation Troubleshooting

• 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 where the features cannot be disabled, you must establish BOTH your twisted pair and fiber connections before the link LEDs will light!

• To test a media converter by itself, first make sure you have an appropriate fiber patch cable, then follow these steps to test:

SStteepp 11::

Connect the media converter to the twisted pair

device with a twisted pair cable.

SStteepp 22::

Loop a single strand of fiber from the transmit port to

the receive port of your media converter.

SStteepp 33::

Verify that you have both twisted pair and fiber link

(see LEDs, below) on your media converter.

• Make sure to use the appropriate twisted pair cable, and have the crossover/pass-through switch set correctly, if your media converter does not include AutoCross.

• If using a high powered device (which is designed for long distance

installations) for a short distance installation, the fiber transmitters may overdrive the receivers and cause data loss. If this is the case, you may need to add an optical attenuator to your connection.

HAT I S

P ULSING F IBERA LERT?

Use Pulsing FiberAlert in the following two situations:

A) When connecting two Compact Media Converters (or connecting one to a 100 Mbps Media Conversion module) with FiberAlert enabled. B) When connecting one Compact Media Converter with FiberAlert enabled and one Compact Media Converter 10/100 unit with Link Fault Detection (LFD) enabled.

NOTE: Pulsing FiberAlert may be useful when connecting Compact Media Converter to another manufacturer’s product that has a similar feature to FiberAlert.

NOTE: Please refer to the Compact Media Converter 10/100 Installation Guide for more information on LFD.

Auto-Negotiation on Compact Media Converter

Compact Media Converter includes Auto-Negotiation. When Auto-Negotiation is enabled (default), the media converter negotiates as a 100 Mbps Full-Duplex device; if the device the Compact Media Converter is connected to can operate at 100 Mbps Full-Duplex, a link will be established.

If the twisted pair port on the other device does not have the ability to auto-negotiate, or if a 100 Mbps Half-Duplex connection is desired, Auto-Negotiation on Compact
