Twisted Pair Crossover/Straight-Through Connections

Whether using crossover or straight-through CAT5 twisted pair cabling, all
Switching Modules will support both types of connections by one of the
following methods:

AutoCross

MDI-II/MDI­X Switch

Device­Dependent

McLIM TX/FX (-00) and McGigabit include AutoCross, a feature that

automatically selects between a crossover workstation or straight­through connection depending on the connected device.

All McPIMs feature a 2-position switch, located at position S1 (see table
for location on boards), for selecting a crossover workstation
connection or straight-through connection.

The switch is labeled with “X” for a crossover connection (factory
default) and an “ll” for a straight-through connection. Select the
appropriate setting by moving the switch to the proper position before
installing the media conversion module. If uncertain whether crossover
or straight-through is needed, set the switch to the position that makes
the link LED glow.

The end device connected to the McLIM TX/FX and TX/SX (-50)
determines the type of twisted pair connection: this McLIM does
include AutoCross or a MDI-II/MDI-X switch.

Twisted Pair Cable Distance

Some McPIM TP/FOs features a 2-position jumper, located at position JP2, for
selecting longer twisted pair cable distances (distances greater than 100 meters).
Place the jumper over both pins for distances up to 100 meters (factory default).
Remove the jumper shunt or place it on only one pin for distances of 100 meters
or more.

NOTE

The product on the other side of the conversion must be able to support longer

cable distances.

Twisted Pair Cable Type

Some McPIM TP/FOs (-20 and -40) features a 2-position jumper, located at
position JP3, for selecting either a shielded or unshielded twisted pair link
segment. Remove the jumper shunt or place it on only one pin to select an
unshielded twisted pair link segment (factory default). Place the jumper shunt
over both pins to select a shielded twisted pair link segment.

5

LinkLoss, FiberAlert and Link Fault Pass-Through

McPIM TP/FO and McLIM TX/FX and TX/SX include the following features:

FO/FX LinkLoss (a.k.a. "Fiber LinkLoss" or "LinkLoss")

•

•

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

•

FiberAlert and Pulsing FiberAlert

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

WARNING

Installing modules without understanding the effects of FiberAlert and LinkLoss can

cause perfectly functioning units to appear flawed or non-functional.

6

Link Integrity

During normal operation, link integrity pulses are transmitted by all point-to­point Ethernet devices. When an B&B Electronics 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 “LNK” (link) LED is lit to indicate this.

The B&B Electronics 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. The
combination of FiberAlert and LinkLoss allows this information to be obtained,
even when physical access to a remote device (and its link integrity LED) is not
available.

FO/FX LinkLoss

FO/FX LinkLoss is a troubleshooting feature. When a fault occurs on the fiber
segment of a conversion, FO/FX LinkLoss detects the fault and passes this
information to the twisted pair segment. If a media converter is not receiving a
fiber link, FO/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.

TP/TX LinkLoss

TP/TX LinkLoss is another troubleshooting feature. When a fault occurs on the
twisted pair segment of a conversion, TP/TX LinkLoss detects the fault and passes
this information to the fiber segment. If a media converter is not receiving a
twisted pair link, TP/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.

7

Link Fault Pass Through

Link Fault Pass Through (LFPT) is a troubleshooting feature that combines TX and
FX LinkLoss from both the local and remote media converter modules (only
available on the McLIM the 100 Mbps TX/FX -00, -10, -20, -30). LFPT is enabled
by turning on both FX and TX LinkLoss on both modules. This feature allows
both end segments of the conversion to detect link faults occurring in the media
conversion chain. FiberAlert can also be added to the remote side of the pair to
further assist in locating a fault.

FiberAlert

FiberAlert minimizes the problems associated with the loss of one strand of fiber.
If a strand is unavailable, the B&B Electronics 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.

WARNING

Enable FiberAlert on ONE side of a media conversion only;

enabling it on both sides will keep both transmitters off indefinitely!

Pulsing FiberAlert

Pulsing FiberAlert minimizes the problems associated with the loss of one strand
of fiber. If a strand is unavailable, the device at the receiver end notes the loss of
link. The device will stop transmitting data and start sending link pulses. Until a
valid link is received, the fiber link LED will be OFF on the device on the receiver
side of the fiber strand with the fault while the fiber Link LED on the other unit
will blink. Pulsing FiberAlert notifies a local site administrator of a fault, allowing
quick determination of where a cable fault resides.

NOTE

Pulsing FiberAlert can be enabled on BOTH sides of a conversion.

Auto Negotiation on 100 Mbps Modules

When Auto Negotiation is enabled, the media converter negotiates as a 100
Mbps Full-Duplex device; if the device the 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 the media converter must be disabled. Half- and Full-Duplex settings must be
manually set and match on both end devices to which the media converters are
connected. The diagram below shows a typical application, followed by a table
with three possible configurations.

Configure Auto Negotiation on 100 Mbps Modules with a 3-pin jumper block
located on the module’s PCB or DIP Switch, depending on the Model. Refer to
the Jumper Configuration Table of this manual to verify jumper position and
default setting.

Auto Negotiation on 10/100 Switching Modules

Auto Negotiation is a standard feature on 10/100 Switching Modules. The fiber
port always operates at 100 Mbps FDX; the copper port auto-senses the
connected device’s speed and duplex mode: 10 Mbps or 100 Mbps and HDX or
FDX (including Flow Control).

NOTE

McLIM TPTX/FX is a Plug-And-Play device, therefore Auto Negotiation is always

enabled.

Installing Media Conversion Modules

The media conversion modules can be installed in any available slot in a media
converter chassis. Media conversion modules are hot-swappable.

Media conversion modules ship with brackets for securing them to the media
converter chassis. To install a module, simply unscrew the blank bracket
converting the slot where the module is installed. Slide the module into the
chassis, via the card guides, until the module is seated securely in the connector.
Hand tighten the thumb screw until snug. Finish tightening the thumb screw
using a screw driver, being careful to not over-tighten.

11

NOTE

Media converter chassis ship with all but one media conversion module slot covered
with “blank” brackets. Be sure to keep unused slots covered for EMI containment. It
is a good idea to save any “blanks” removed during installation for future use if
configuration requirements change.

Installation Tip

Since single-strand fiber products use optics that transmit and receive on two
different wavelengths, the single-strand fiber products must be deployed in pairs, or
connect two compatible B&B Electronics single-strand fiber products. For example,
connect Compact Media Converter, TX/SSFX-SM1310-SC (which has 1310 xmt and
1550 rcv) to a product which has 1550 xmt and 1310 rcv, e.g. 100 Mbps TX/SSFX­SM1550-SC Module. The two connected products must also have the same speed
and distance capabilities (i.e. both are single-mode [20 km] or both are single/PLUS
[40 km]).

12

Power Supply Installation

When installing a redundant power supply module into a powered-on 12-Slot
chassis, B&B Electronics recommends setting the ON/OFF switch on the module
(if present) to OFF. After installing the power supply, turn its switch ON.

If the redundant power supply module does NOT have an ON/OFF switch, B&B
Electronics recommends powering-down the chassis before installing the power
supply. Turn the chassis back ON after installing the power supply.

LED Operation

Each media conversion module features diagnostic LEDs (see diagrams below)
that provide information on features and ports.

Installation Troubleshooting

The following information assists in troubleshooting the Modular Media
Converters:

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 connect, establish

•
BOTH the twisted pair and fiber connections in order to establish link LEDs.

To test a media converter by itself, have an appropriate fiber patch cable,

•
then follow these steps to test:

1.

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

Loop a single strand of fiber from the transmit port to the receive port of the

2.
media converter.

3.

Verify that both the twisted pair and the fiber link (see LEDs, below) on the
media converter.

NOTE

Use caution when conducting a loopback test; it is possible to create a network loop
if connecting the twisted pair port to an active network switch. B&B Electronics
recommends connecting the twisted pair cable to a PC for this type of test.

•

Make sure to use the appropriate twisted pair cable, and have the
crossover/straight-through switch set correctly if the 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, an optical
attenuator may need to be added to the connection.

Grounding

If installed in a closed or multi-unit rack assembly, the operating
ambient temperature of the rack environment may be greater
than room ambient. Therefore, consideration should be given to
installing the equipment in an environment compatible with the
maximum ambient temperature (Tma) specified by the
manufacturer.

Installation of the equipment in a rack should be such that the
amount of air flow required for safe operation of the equipment is
not compromised.

Consideration should be given to the connection of the
equipment to the supply circuit and the effect that overloading of
the circuits might have on over current protection and supply
wiring. Approximate consideration of equipment nameplate
ratings should be used when addressing this concern.

Reliable grounding of Rackmounted equipment should be
maintained. Particular attention should be given to supply
connections other than direct connections to the branch circuit
(e.g. use of power strips).

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.

Use fiber patch cords (or connectors, if you terminate your own fiber) only

1.
from a reputable supplier; low-quality components can cause many hard-to­diagnose problems in an installation.

2.

Dust caps are installed at B&B Electronics to ensure factory-clean optical
devices. These protective caps should not be removed until the moment of
connecting the fiber cable to the device. Should it be necessary to
disconnect the fiber device, reinstall the protective dust caps.

Store spare caps in a dust-free environment such as a sealed plastic bag or

3.
box so that when reinstalled they do not introduce any contamination to the
optics.

4.

If it is suspected 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 any product, add-in modules
or stand alone units, containing electronic components. Always observe the
following precautions when installing or handling these kinds of products

1.

Do not remove unit from its protective packaging until ready to install.

2.

Wear an ESD wrist grounding strap before handling any module or
component. If the wrist strap is not available, maintain grounded contact
with the system unit throughout any procedure requiring ESD protection.

3.

Hold the units by the edges; do not touch the electronic components or gold
connectors.

After removal, always place the boards on a grounded, static-free surface,

4.
ESD pad or in a proper ESD bag. Do not slide the modules or stand alone
units over any surface.
