About the iMcV-Modules
iMcV-Modules are SNMP-manageable and install in the modular, SNMP-
manageable iMediaChassis series in the unmanaged MediaChassis series. The
following media conversion and fiber mode conversion iMcV Modules are
described in this manual:
iMcV-PIM
Ethernet module providing a single conversion between 10Base-T
twisted pair and 10Base-FL single-mode or multi-mode fiber. Each
iMcV-PIM includes one RJ-45 connector and one pair of ST or SC fiber
optic connectors. When connecting 10 Mbps iMcV-PIM Media
Converters, the end devices must be set to Force mode.
TP LinkLoss and FO LinkLoss are always enabled—please see the
table later in this manual.
iMcV-LIM
Fast Ethernet module 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.
Also available in a single-strand fiber version, iMcV-LIM TX/SSFX
allows two wavelengths to share one fiber strand –Full-Duplex data
travels on different wavelengths (1310 nm and 1550 nm) –doubling the
capacity of fiber. Includes one RJ-45 connector and one SC fiber
connector.
iMcV-S2MM/
M2MM/S2SM
Protocol-independent modules provide a single conversion between
single-mode and multi-mode (S2MM*) fiber, 1310 nm to 1550 nm
single-mode (S2SM), or 850 nm to 1300 nm multi-mode (M2MM).
Supported transmission speeds are: 10-155 Mbps and 622-1250Mbps.
Each module includes two pairs of ST or SC fiber optic connectors (or
small form factor connector). Single-strand fiber versions also available.
Installation
iMcV-Modules install in any B&B Electronics SNMP-manageable iMediaChassis
series or in any MediaChassis. To install an iMcV-Module, remove the blank
bracket covering the slot where the module is to be installed by removing the
screw on the outside edge of the bracket. Slide the iMcV Module into the
chassis, via the card guides, until the module is seated securely in the connector.
Secure the module to the chassis by tightening the captive screw. Save any
blanks removed during installation for future use should configuration
requirements change.
LED Operation
Each iMcV-Module features diagnostic LEDs that provide information on features
and ports.

Configuration Instructions
Many iMcV-Modules have user-configurable features (e.g., FiberAlert, LinkLoss,
Auto Negotiation, etc.). Refer to the chart for information on available features on
each module. Instructions for configuring both managed (via an SNMP-
compatible management application such as iView²) and unmanaged modules
follow.
Managed Modules
To manage one or more iMcV-Modules, an SNMP agent must be present in the
chassis. The iMediaChassis series, available in 3, 6 or 20 slots in both AC and
DC, requires a separate SNMP Management Module. To configure managed
modules, install the module first, then configure it by using the management
software.
NOTE
Management software overrides any hardware settings (e.g., jumper, switch, etc.), so
make sure the module is configured through the software before beginning normal
operation. Until a module installed in a managed chassis is configured via the software, it
will operate using the hardware configuration.
Unmanaged Modules
Before beginning installation of the iMcV-Modules, configure them for the desired
features. The chart below states the available features and settings for the
iMcV-PIM and iMcV-LIM modules. The board diagrams later in this manual show
the jumper/switch locations on the modules. Since there are no user-
configurable features on the iMcV-S2MM/S2SM/M2MM modules, they can
be installed straight from the box.
After configuring the jumpers/switches for the desired settings, install the module
and connect the appropriate cables (refer to the Installation section for more
information).

Some iMcV-Modules include advanced troubleshooting features that help locate
silent failures on the network. Troubleshooting features include:
 FO/FX LinkLoss (a.k.a. Fiber LinkLoss or LinkLoss)
 TP/TX LinkLoss (a.k.a. Twisted Pair LinkLoss or Reverse LinkLoss)
 FiberAlert
 Pulsing FiberAlert
It is important to understand how FiberAlert and LinkLoss work, and how they will
react in a specific 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 even nonfunctional.
About Link Integrity
During normal operation, link integrity pulses are transmitted by all point-to-point
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

7
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.
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.
NOTE
Enable FiberAlert only on one side of the media conversion; enabling it on both sides will
keep both transmitters off indefinitely.
Pulsing FiberAlert
Available on products 850-14940 through 850-14949 (board revision -10),
Pulsing 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 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.
Using FiberAlert and LinkLoss

Twisted Pair Crossover/Straight-Through Connections
iMcV-Modules support both crossover and straight-through CAT5 twisted pair
cabling types of connections by one of the following two methods:
AutoCross
IMcV LIM Modules include AutoCross, a feature which
automatically selects between a crossover workstation or
straight-through/repeater hub connection depending on the
connected device.
MDI/MDI-X Switch
iMcV-PIMs feature a push button switch, located next to the RJ-
45 connector, for selecting the type of connection. Select a
straight-through connection by pressing the push-button IN. The
button should be in the OUT position for a crossover connection.
If unsure of the type of connection, set the push button to a
position that makes the twisted pair LNK (link) LED glow.
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
device the IMcV LIM 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 IMcV LIM must be disabled. Half- and Full-Duplex settings must
be manually set, and match, on both devices connected to the IMcV LIM. The
following diagram shows a typical application, followed by a table with three
possible configurations.

Installation Troubleshooting
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, it is necessary to
establish BOTH the twisted pair and fiber connections before the link LEDs will
light.
To test a media converter by itself, first make sure to 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.
2. Loop a single strand of fiber from the transmit port to the receive port of
the media converter.
3. Verify that there are both twisted pair and fiber link (see LEDs, below)
on the media converter.
Make sure to use the appropriate twisted pair cable, and have the
crossover/pass-through switch set correctly.
When connecting 10 Mbps iMcV-PIM Media Converters, the end devices must be
set to Force mode.

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 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.
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 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.
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 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.
