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 con-
nection.  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 but-
ton 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).

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 strong-

ly encourages you to read the following information. Contact IMC Networks

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 com-
ing 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

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 protec-
tive 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 (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.
