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, you must
establish BOTH your twisted pair and fiber connections before the link LEDs
will light!

•

To test a media converter by itself, first make sure you have an appropriate
fiber patch cable, then follow these steps to test:

1.

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
your media converter.

3.

Verify that you have both twisted pair and fiber link (see LEDs, below) on
your media converter.

•

Make sure to use the appropriate twisted pair cable, and have the
crossover/pass-through switch set correctly.

•

Whenever possible, set the devices connected to the media converter (hub,
switch, NIC card) to the desired speed and Duplex setting, and turn Auto­Negotiation OFF. (See page 7 for information on Auto-Negotiation.) Also
make sure to configure the devices on the opposite sides of the media
converter to operate at the same speed and Duplex setting.

NOTE

Some 10/100 devices can't be set by the end user, and must auto-negotiate to
receive a signal.

LED Operation

Each iMcV Module features diagnostic LEDs that provide information on features
and ports.

LEDs on iMcV-LIM and iMcV-PIM

The LEDs and their locations are the
same on iMcV-LIM and iMcV-PIM
Modules. The LED functions are as
follows:

•

LL - Glows green when FX LinkLoss

is enabled.

•

LNK

- Glows green when a link is

established on the port.

•

XMT

- Blinks green when port is

transmitting data.

•

RCV

- Blinks yellow when port is

receiving data.

•

FA* - Glows green when FiberAlert is

enabled.

*FiberAlert is not available/applicable on
single-strand versions of iMcV-LIM.

LEDs on iMcV-S2MM/S2SM/M2MM

The LED functions on iMcV-S2MM/S2SM/M2MM are as follows:

•

ENA

Glows green when port is enabled.

•

ACT

Glows yellow in normal operation, indicating that fiber is connected and
the receiver is seeing light pulses. (As these are protocol-independent
modules, there is no true “link” signal available.)

About the iMcV-Modules

iMcV Modules are SNMP-manageable and install in the modular, SNMP­manageable iMediaChassis, iMediaCenter, and 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.

•

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 iMcV­LIM includes one RJ-45 connector and one pair of ST or SC fiber optic
connectors (or one small form factor connector).

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 single­mode and multi-mode (S2MM*) fiber, 1300 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- 1250 Mbps. Each module includes two
pairs of ST or SC fiber optic connectors (or small form factor connector).
Single-strand fiber versions also available.

For information about other iMcV Modules refer to their respective manuals, and
datasheets on the IMC Networks Web site at:

http://www.imcnetworks.com/tech/techsup.asp

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 SNMP­compatible management application like iView²) and unmanaged modules
follow.

Managed Modules

To manage one or more iMcV Modules, an SNMP agent must be present in the
chassis: an iMediaCenter chassis has embedded management where an
iMediaChassis chassis uses an SNMP module. To configure managed modules,
install the module first, then configure it by using the management software.
Refer to the iView² for Media Converters online help for more information and
assistance.

NOTE

Management software overrides any hardware settings (e.g., jumper, switch, etc.),
so you must 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 on page 2 states the available features and settings for the
iMcV-PIM and iMcV-LIM modules. The diagrams on the next page show the
jumper/switch locations on the modules. There are no user-configurable features
on the iMcV-S2MM/ S2SM/ M2MM modules; which can therefore 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).

7

If the twisted pair port on the other device does not have the ability to auto­negotiate, 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 follwing
diagram shows a typical application, followed by a table with three possible
configurations.

End to End Connection Switch McPC TX/FX

Half-Duplex Manually Configure HDX Auto-Negotiation OFF

Full-Duplex Manually Configure FDX Auto-Negotiation OFF

Full -Duplex Auto-Negotiation ON Auto-Negotiation ON

Configure Auto-Negotiation on an iMcV-LIM by adjusting the DIP switch setting
(for unmanaged modules) or via the management software. Refer to the diagrams
in this manual for switch location and settings.

Installation

iMcV Modules install in any IMC Networks SNMP-manageable media converter
chassis 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
screws on the outside edges of the bracket. Slide the iMcV Module into the
chassis, via the cardguides, 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.

Configuring LinkLoss and FiberAlert

iMcV-PIM and iMcV-LIM Modules ship from the factory with troubleshooting
features disabled. See the configuration instructions in this manual for
instructions on enabling FiberAlert and LinkLoss.

Twisted Pair Cable Type

The twisted pair port on iMcV-McPIMs features a jumper, located at position JP6,
for selecting either a shielded or unshielded twisted pair link segment. The
factory default is unshielded twisted pair with the jumper shunt on pins 1-2.
Place the jumper shunt over pins 2-3 to select a shielded twisted pair link
segment.

NOTE

This jumper is not found on -20 iMcV-McPIM boards.

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 Auto­Negotiation 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.

About LinkLoss and FiberAlert

Some iMcV Modules include advanced troubleshooting features that help locate
"silent failures" on your 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

It is important that you understand how FiberAlert and LinkLoss work, and how
they will react in your 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 dead.

About Link Integrity

During normal operation, link integrity pulses are transmitted by all point-to-point
Ethernet devices. When an IMC Networks 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 IMC Networks 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.

What Is 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.

5

What Is TP/TX LinkLoss?

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.

What Is FiberAlert?

FiberAlert minimizes the problems associated with the loss of one strand of fiber.
If a strand is unavailable, the IMC Networks 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!

Using FiberAlert and LinkLoss

The following chart provides an overview of the troubleshooting features, their
functionality and the recommended settings for a pair of media converters in a
typical central/main site to remote site application:

FiberAlert and LinkLoss

Feature Enabled Fault Location Disabled LEDs

FiberAlert

Remote Site Only Fiber Fiber

TX LinkLoss

Remote Site Only Twisted Pair Fiber

FX LinkLoss

Home Site (or both) Fiber Twisted Pair

his will ensure that any faults, no matter where they occur, can be detected by an
administrator located at the central site.
