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.

Selective Advertising is a mode in which the speed and duplex for the copper and the
fiber are specifically advertised. This mode is available when DSW 1-4 are set to OFF.

Troubleshooting Features

The iMcV-LIM 10/100 media converters include two advanced troubleshooting
features to help locate “silent failures” on the network.

 Transparency
 Link Fault Detection (LFD)

Transparency

Transparency is only available in PNP mode. Transparency treats the connection
between the two end devices as if there were no media converters installed. In a
typical application where two media converters are installed between two copper­based switches, the twisted pair cables as well as the fiber cable are seen as one
entity. If a fault occurs on any segment between the two end devices, link LEDs on
the end devices will go out. This prevents any failure on the link between the end
units from going undetected.

Link Fault Detection in FORCE Modes (LFD)

Link Fault Detection (LFD) is only available when using Force 10 or Force 100 mode
and provides the same information as link fault pass through as does in PNP mode to
detect silent failures. When LFD is enabled and the input link is down at one
interface to the iMcV-LIM 10/100, the transmitter output on that interface is turned
off for about 425ms every 3.8 seconds (i.e., blinking). It applies to both network
interfaces and to both data rates. If the link at the other interface to the iMcV-LIM
10/100 is also down, there is no output. LFD causes the Link Up indicator of the link
partner to blink.

When the iMcV-LIM 10/100 is in one of the FORCE modes, enable LFD by setting S1
to the ON position.

In order for LFD to function properly, Force mode must be enabled by setting:

 S3 to ON with either S4 ON for 10 Mbps or S4 OFF for 100 Mbps
 S2 must also be OFF

NOTE

When using the LFD feature, if the DIP Switches are in any other combination than listed
above, the iMcV-LIM 10/100 may exhibit erratic behavior.

As stated, transparency is available when iMcV-LIM 10/100 is operating in PNP (AN)
mode:

 S2 PNP (AN) must be ON
 S1 (LFD), S3 (Force) and S4 (10 or 100) must be OFF

Glows green when a twisted pair link is established.

LNK

Glows yellow when data is detected on the port.

ACT

(AN)

Glows green when unit has power.

PWR

Fiber Port

Glows yellow when 100 Mbps data is detected on the

100

port.

Glows green when data is detected on the port.

ACT

LNK

Glows green when a fiber link is established.

NOTE

Before either LNK LED will glow solid, the twisted pair and fiber optic cables must be
connected and the twisted pair crossover/ pass-through switch set correctly.

The 10/100 Autosensing Modules includes two advanced troubleshooting features,
Transparency and Link Fault Detection, to help locate “silent failures” on the
network.

Transparency

Transparency is only available when using AN. When the 10/100 Autosensing
Modules is Auto Negotiating, transparency treats the connection between the two
end devices as if there were no media converters installed. For example, in a typical
application where two media converters are installed between two copper-based
switches the twisted pair cables as well as the fiber cable are seen as “one” entity. If a
fault occurs on any segment between the two end devices, link LEDs on the end
devices will go out.

Since transparency is only available when the 10/100 Autosensing Modules is
operating in Auto Negotiation mode, S2 (AN) must be ON and S1 (LFD), S3 (Force)
and S4 (10/100) must be OFF.

Link Fault Detection

Link Fault Detection (LFD) is only available when using Force 10 or Force 100 mode.
When LFD is enabled and the input link is down at one interface to the 10/100
Autosensing Modules, the LFD LED will blink. This applies to both network interfaces
and to both data rates. If the link at the other interface to the 10/100 Autosensing
Modules 10/100 is also down, there is no output and LFD causes the Link LED to
blink.

When the 10/100 Autosensing Modules is in one of the Force modes, enable LFD by
setting S1 to the ON position. In order for LFD to function properly, Force mode
must be enabled by setting S3 to ON with S4 set for the proper speed.

6

Twisted Pair Crossover/Pass-Through Switch

The iMcV-LIM 10/100 features a crossover/pass-through push-button switch, located
on the faceplate next to the RJ-45 connector, to set the twisted pair connection type.
Select a pass-through connection by pressing the push-button IN. A crossover
connection is selected when the push-button is OUT. If it is not clear which
connection is needed, set the push-button to whatever setting makes the twisted pair
LNK LED glow.

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 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.

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.
