Operation Manual
FCC Radio Frequency Interference Statement
This equipment has been tested and found to comply with the limits for a Class B computing device, pursuant to Part 15 of the FCC Rules.
These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial
environment. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the
instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to
cause harmful interference in which the user will be required to correct the interference at his own expense.
Any changes or modifications not expressly approved by the manufacturer could void the user’s authority to operate the equipment.
The use of non-shielded I/O cables may not guarantee compliance with FCC RFI limits. This digital apparatus does not exceed the Class B

IN THIS SECTION SHALL EXTEND TO THE ORIGINAL USER ONLY, IS IN LIEU OF ANY AND ALL OTHER
WARRANTIES, EXPRESS OR IMPLIED, AND ALL SUCH WARRANTIES AND INDEMNITIES ARE EXPRESSLY DISCLAIMED,
INCLUDING WITHOUT LIMITATION (I) THE IMPLIED WARRANTIES OF FITNESS FOR A PARTICULAR PURPOSE AND
OF MERCHANTABILITY AND (II) ANY WARRANTY THAT THE PRODUCTS ARE DO NOT INFRINGE OR VIOLATE THE
INTELLECTUAL PROPERTY RIGHTS OF ANY THIRD PARTY. IN NO EVENT SHALL B&B ELECTRONICS BE LIABLE FOR
LOSS OF BUSINESS, LOSS OF USE OR OF DATA INTERRUPTION OF BUSINESS, LOST PROFITS OR GOODWILL OR
OTHER SPECIAL, INCIDENTAL, EXEMPLARY OR CONSEQUENTIAL DAMAGES. B&B ELECTRONIC SHALL
DISREGARD AND NOT BE BOUND BY ANY REPRESENTATIONS, WARRANTIES OR INDEMNITIES MADE BY ANY

The iMcV-LIM 10/100 is an SNMP-manageable, IEEE 802.3 single-conversion media
conversion module which converts between:
10Base-T twisted pair and 10Base-FL multi-mode or single-mode fiber, or
100Base-TX twisted pair and 100Base-SX multi-mode fiber, 100Base-FX single-
mode fiber or single-strand single-mode fiber.
The iMcV-LIM requires one slot in an SNMP-manageable chassis or an unmanaged
chassis from B&B Electronics. The iMcV-LIM features one RJ-45 connector and one
pair of ST or SC fiber connectors.
Configuration Instructions
In many networks, the media converter is typically installed as a pair, between two
copper-based end devices. The iMcV-LIM 10/100 can also be installed as a single
media converter, between one copper-based device and the other a fiber-based
device. However, when connected to certain fiber-based devices, there may be
difficulty in the installation: if a link partner that is connected to the iMcV-LIM 10/100
media converter is powered down on the copper port, noise on the copper segment
may be detected and transferred to the fiber line. A result of the noise will generate
errors that look like CRC errors. Some fiber-based devices many detect this noise and
disable the fiber segment.

Installing an iMcV-LIM 10/100
Modes of Operation
The iMcV Modules install in B&B Electronics’ SNMP manageable iMediaChassis series
or in any MediaChassis.
NOTE
All modules are hot-swappable.
To install an iMcV Modules:
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.
Managed Modules
To manage one or more iMcV-LIM 10/100, an SNMP agent must be present in the
chassis. To configure Managed Modules, install the module first, and then configure
using the management software. If using management software, software will
override hardware DIP Switch settings.
Unmanaged Modules
Before installing, configure the iMcV-LIM 10/100modules for desired features. Refer
to table which indicates the available features and settings for the iMcV-LIM 10/100
modules.
The iMcV-LIM 10/100 has four modes of operation:
PNP (Auto Negotiation)
FORCE 10Mbps
FORCE 100Mbps
Selective Advertising AN (All OFF)
NOTE
The iMcV-LIM 10/100 cannot be set for Half- or Full-Duplex manually. Duplex is determined
by the link partners connected to the iMcV-LIM 10/100.
The iMcV-LIM 10/100 media converter is typically installed in pairs and provides
compatibility with legacy 10BASE-FL devices, while also providing support for
100Mbps devices. This is a PHY based device to allow very low propagation delays
but in turn the speed and duplex of both its copper and fiber ports must be the same.
For the iMcV-LIM 10/100 to function properly, the copper port must have link before
the fiber port will link up.
In a back to back configuration, both units must have the Plug-N-Play
PNP (AN)
switch set to ON for the copper ports to auto negotiate from end to end. In this
mode the fiber link becomes transparent allowing the units at both ends of the link to
function as if they were connected over one copper line. All auto negotiation
signaling is the result of signaling received on the ports of the unit. Only use this
mode with two iMcV-LIM 10/100 media converters installed as a pair.

With all switches set to OFF
,
the unit sends its own
Selective Advertising (AN)
signaling on the copper port. This advertises both FDX and HDX with the physical
speed that is detected on the fiber line. This signaling cannot occur until this fiber
port is active. If auto negotiation signaling is also received over the fiber from the far
end equipment, the auto negotiation signaling on the copper port will include this
information.
In all of the
FORCE modes
, no auto negotiation signals are sent or acted on. The unit
will blindly send the speed assigned and supports either FDX or HDX data. The LFD
function is only available in the FORCE modes.
