ABOUT IMCV-LIM
The iMcV-LIM is a Fast Ethernet module which provides a single conversion
between 100Base-TX `twisted-pair and 100Base-FX/SX single-mode or multi-
mode fiber. Each iMcV-LIM includes one RJ-45 connector and one pair of ST
or SC fiber optic connectors, and/or an SFP port, which can support any fiber
type. Models with Configuration Control are identified by a label on the
faceplate of the module.
Also available in a single-strand fiber version, iMcV-LIM TX/SSFX and iMcV-
LIM TX/SFP with Configuration Control allow two wavelengths to share one
fiber strand — Full-Duplex data travels on different wavelengths, for example
(1310 nm and 1550 nm) — doubling the capacity of fiber.
The iMcV-LIM is SNMP-manageable and can be installed into the modular,
SNMP-manageable iMediaChassis, as well as the MediaChassis series, which
are unmanaged.
NOTE: Some options require items that are sold separately, available from B+B
SmartWorx.
CONFIGURATION
The iMcV-LIM has user-configurable features (e.g., FiberAlert (FA), TX
LinkLoss (TXLL), FX LinkLoss (FXLL), Link Fault Pass-Through (LFPT) and
Far End Fault (FEF)). Refer to the iMcV module DIP Switch configuration table
for information on available features. Instructions for configuring both
managed (via an SNMP-compatible management application like iView²) and
unmanaged modules follow.
INSTALLING IMCV MODULES
The iMcV modules install in B+B SmartWorx’ SNMP manageable
iMediaChassis series or in any MediaChassis.
To install an iMcV module:
1. Remove the blank bracket covering the slot where the module is to be
installed by removing the screws on the outside edges of the bracket.
2. Slide the iMcV modules into the chassis, via the cardguides, until the module
is seated securely in the connector.
3. Secure the module to the chassis by tightening the captive screw.
4. Save any “blanks” removed during installation for future use if the
configuration requirements change.
NOTE: All modules are hot swappable.

MANAGED MODULES
To manage one or more iMcV-LIM(s), an SNMP agent must be present in the
chassis. To configure Managed Modules, install the module first, and then
configure using the management software.
Fiber type, serial number and date code are now loaded into the NVRAM
during manufacturing. This is viewed only via iView² software, within the
modules details.
Requirements:
•SNMP Firmware version C2
•iView² 1.8.6 or higher
NOTE: For iMcV-LIM modules without Configuration Control, management software
overrides any hardware settings (e.g., jumper, switch, etc.); a module must be configured
so that it will be managed via the software.
IMCV-LIM & CONFIGURATION CONTROL
The iMcV-LIM with SFP offers Configuration Control; a label on the front
faceplate identifies the unit as such. Configuration Control has been
implemented to assist the end user by retaining the latest configuration
regardless of how that configuration was implemented (via DIP Switch settings
or SNMP).
Historically, SNMP would override DIP Switch settings. If changes are made
via DIP Switch settings, then hardware settings determine the configuration of
the board. If changes are made to the module via iView2, the SNMP settings
determine the configuration of the board.
Utilizing Configuration Control, the end user has three conditions under which
the configuration of the iMcV module may be impacted:
•Installing an iMcV-LIM into a chassis already loaded with iMcV modules
or replacing an iMcV-LIM
- The iMcV module will transfer its saved configurations. The iMcV-LIM
will not override the module’s configuration.
•Replacing the same type of iMcV module
- If the DIP Switch settings are the same as the settings on the
removed iMcV module, the iMcV-LIM determines the configuration
settings.
- If the DIP Switch settings are different, then the configuration of the
module is determined by the DIP Switch settings. (The settings are
forwarded to the iMcV-LIM and the value is saved.)
•Installing a new model of iMcV module

iMcV-LIM
6
- If another type of module is installed into the same slot in a chassis,
the iMcV-LIM clears the memory of the previous configuration for that
slot; the settings of a new module are adopted and stored in the
iMcV-LIM
The SNMP Write Lock switch does not impact any iMcV module or iMcV
module with Configuration Control. Removing and installing a new SNMP
Management Module will no longer impact these modules either. However, if
there is a mixture of iMcV modules with and without Configuration Control, the
Write Lock Switch and a new SNMP Management Module must be taken into
consideration.
If the command cleandb is applied to an SNMP Management Module, all the
settings for the modules will be removed, but the Configuration Control
modules will still be based on the last change made, while those without
Configuration Control will be set to their default settings.
NOTE: If the end user has a mixture of standard iMcV modules as well as Configuration
Control iMcV modules, it is important to understand how SNMP and DIP Switches will
impact the cards depending on their capability. Standard iMcV modules cannot be
upgraded to Configuration Control capability, so it is strongly recommended to set the DIP
Switches on the modules and then configure them via software to match the same settings.
UNMANAGED MODULES
Before installing, configure the iMcV-LIM modules for desired features. The
table below indicates the available features and settings for the iMcV-LIM
modules.
After configuring the DIP Switches for the desired settings, install the module
and connect the appropriate cables (refer to Installing an iMcV-LIM section for
more information).

FX LINKLOSS, TX LINKLOSS, LINK FAULT PASS-THROUGH, FAR
END FAULT, FIBERALERT
iMcV-LIM modules include the troubleshooting features FiberAlert, TXLL,
FXLL, FEF and LFPT that help locate silent failures on a network. Before
attempting to install the module(s), understand how these features work and
react to a specific network configuration.
Link Integrity
During normal operation, link integrity pulses are transmitted by all point-to-
point Ethernet devices. When an B+B SmartWorx 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 SmartWorx 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.
FX LinkLoss (FXLL)
FX LinkLoss is a troubleshooting feature. When enabled, if a fault occurs on
the fiber segment of a conversation, 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, and the TXLL LED will blink.
TX LinkLoss (TXLL)
TX LinkLoss is a troubleshooting feature. When enabled, if 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 the link on the device
connected to the fiber port, and the FXLL LED will blink.

iMcV-LIM
10
Link Fault Pass-Through (LFPT)
Link Fault Pass-Through (LFPT) is a troubleshooting feature that combines TX
and FX LinkLoss from both the local and remote iMcV-LIM modules. LFPT is
enabled by turning on both FX and TX LinkLoss on both modules. This feature
allows either end of the conversion to detect a link fault occurring at the other
end of the media conversion chain.
Regardless if there is a break in segment 1, 2 or 3, the link will drop on the
switches at both ends. The link fault is passed through the media conversion
and is observed at each end. It acts just like it would if the devices were
directly connected.

iMcV-LIM
11
FIBERALERT AND FAR END FAULT
Modules ship from the factory with troubleshooting features disabled. Refer to
the Help file to enable/disable this feature.
FiberAlert (FA)
FiberAlert minimizes the problems associated with the loss of one strand of
fiber. If a strand is unavailable, the B+B SmartWorx 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 at the remote side of a media conversion only. Enabling it on both sides would keep both transmitters
disabled indefinitely.
By default FA is disabled. When enabled if, a fault occurs on the fiber line,
affecting data in one direction, FA stops sending signal in the opposite
direction. FXLL will act on this lack of signal, propagating the loss of like to the
copper port when FXLL is enabled.
Far End Fault
By default, FEF is disabled. When enabled, and a fault occurs on the fiber line,
affecting data in one direction, an FEF signal will be sent in the opposite
direction, indicating the fault. FXLL will act on this signal propagating the loss
of link to the copper port when FXLL is enabled.

iMcV-LIM
12
FEF versus FA
FEF is preferred when the devices at both ends of the fiber can interpret the
FEF signal. This allows FEF to be turned on at both ends, which will engage
the FEF regardless of which direction the fault occurs. (Please refer to
diagram on previous page) For example if a fault should occur on segment 2
in the direction of segment 1 to 3, FEF would be engaged on the iMcV-LIM
between segment 2 and 3. This would then send a signal back to the iMcV-
LIM between segment 1 and 2. If the iMcV-LIM between segment 1 and 2 is in
a managed chassis, the chassis would send a trap that the port is down.
Alternatively, if the iMcV-LIM is not in a managed chassis, FXLL could be
engaged to propagate the fault onto the copper port; this would cause
segment 1 to show no link on both ends.
FA is used when connecting to a device that does not support FEF. If an FEF
signal is sent to a device that does not support FEF, the device acts as if there
is still a good connection. The FEF signal is mistaken for data. FA works
similar to FEF, in that when there is a fault in one direction of the fiber, it acts
on the fiber in the opposite direction. But unlike FEF, FA sends no signal.
Because of this, FA can not be enabled on both ends. If it is enabled and a
fault occurs, FA will turn signal off in the opposite direction; the device on the
other side of the fiber will see the loss of signal and engage FA, turning off
signal. The net result will be the signal turned off in both directions, even after
the fault has been repaired.
It is highly recommended that only one is chosen, either FEF or FA. If both are
selected FA will take precedence over FEF.
AUTO NEGOTIATION ON IMCV-LIM
iMcV-LIM modules include the feature Auto Negotiation. When Auto
Negotiation is enabled, the module negotiates as a 100 Mbps full-duplex
device. If the connected device can operate at 100 Mbps full-duplex, a link is
established. Auto Negotiation (DIP Switch #1) is enabled by default.
If the `twisted-pair port on the other device does not have the ability to Auto
Negotiate or if the 100 Mbps half-duplex connection is desired, then Auto
Negotiation must be disabled. Half- and full-duplex settings must be set
manually and match on does devices.
The following diagram shows a typical application and with three possible
configurations.

Configure Auto Negotiation on an iMcV-LIM by adjusting the DIP Switch
setting (for unmanaged modules) or via the management software. Refer to
the DIP Switch table for switch location and settings.
AUTOCROSS FEATURE FOR TWISTED-PAIR CONNECTION
All twisted-pair ports on the iMcV-LIM includes AutoCross, a feature that
automatically selects between a crossover workstation and a straight-through
connection depending on the connected device.

TROUBLESHOOTING - INSTALLATION
•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, establish
both the `twisted-pair and fiber connections before the link LEDs will light.
•To test a iMcV-LIM by itself, first have an appropriate fiber patch cable, then
follow these steps to test:
1. Connect the iMcV-LIM to the `twisted-pair device with a `twisted-pair
cable.
2. Loop a single strand of fiber from the transmit port to the receive port of
the iMcV-LIM.
3. Verify that both the `twisted-pair and the fiber link are lit (see LEDs,
below) on the iMcV-LIM.
4. Use the appropriate `twisted-pair cable, and have the crossover/pass-
through switch set correctly.
5. Whenever possible, set the devices connected to the iMcV-LIM (hub,
switch, NIC card) to the desired speed and Duplex setting, and turn
Auto Negotiation OFF. Refer to Auto Negotiation on iMcV-LIM, also
configure the devices on the opposite sides of the iMcV-LIM to operate
at the same speed and Duplex setting.
NOTE: Some 10/100 devices cannot be set by the end user, and must Auto Negotiate to receive a signal.

ELECTROSTATIC DISCHARGE (ESD) 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 units by the edges; do not touch the electronic components or gold connectors.
4. After removal, always place boards on a grounded, static-free surface, ESD pad or in
a proper ESD bag. Do not slide the modules or stand-alone units over any surface.
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.
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 the factory 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.
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. 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.
