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

- 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.

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.
