TWISTED PAIR CROSSOVER/PASS-THROUGH
CONNECTIONS
Whether you are using crossover or straight-through CAT5 twisted pair
cabling, McBasic TX/FX will support both types of connections by one of
the following methods:
AutoCross: McBasic TX/FX (-50) includes AutoCross, a feature which
automatically selects between a crossover workstation or pass-through/
repeater hub connection depending on the connected device.
NOTE: The MDI/MDI-X button is NOT required on this model.
MDI/MDI-X Switch: McBasic TX/FX (-30 and -40) feature a push button
switch, located next to the RJ-45 connector, for selecting the type of connection. A pass-through connection is selected when the push-button is
pushed IN. To select a crossover connection the button should be in the
OUT position. If you are unsure of the type of connection, set the push button to a position that makes the twisted pair LNK (link) LED glow.
About FiberAlert and LinkLoss
McBasic TX/FX 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
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).
FIBER OPTIC CLEANING GUIDELINES
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) Dust caps are installed at IMC Networks 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.
ELECTROSTATIC DISCHARGE PRECAUTIONS
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.
WARRANTY
During normal operation, link integrity pulses are transmitted by all
point-to-point Ethernet devices. When an IMC Networks 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 IMC Networks media converter also sends out link pulses from its

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, IMC Networks strongly encourages you to read the following information. Contact IMC Networks
technical support at (800) 624-1070 (U.S. and Canada), +32-16-550880
(Europe) or [email protected] for more information/assistance.
ABOUT LINK INTEGRITY
• To test McBasic TX/FX by itself, you must have an appropriate fiber
patch cable. First, connect McBasic TX/FX to the twisted pair device
with a twisted pair cable. Next, loop a single strand of fiber from the
transmit port to the receive port of your media converter. Finally, verify that you have both twisted pair and fiber link on your media converter.
• If attempting to use 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.
Please visit our Web site at www.imcnetworks.com/adocs/fcs.asp for
fiber specifications, or contact IMC Networks for more information.

WHAT IS FX LINKLOSS?
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.
WHAT IS TX LINKLOSS?
McBasic TX/FX features four diagnostic LEDs. The functions are:

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.

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.
ELECTROSTATIC DISCHARGE PRECAUTIONS
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.
WARRANTY
During normal operation, link integrity pulses are transmitted by all
point-to-point Ethernet devices. When an IMC Networks 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 IMC Networks media converter also sends out link pulses from its
