About the iMcV-Giga-MediaLinX

The iMcV-Giga-MediaLinX™ is an SNMP-manageable, IEEE 802.3
10/100/1000 switching media converter that converts both speed and
media. Each iMcV-Giga-MediaLinX module provides a single conversion
between one of the following:

• 10Base-T twisted pair and 1000Base-SX/LX multi-mode or single-mode
fiber

• 100Base-TX twisted pair and 1000Base-SX/LX multi-mode or single­mode fiber

• 1000Base-T twisted pair and 1000Base-SX/LX multi-mode or single­mode fiber.

LED and Port Operation

The LED functions for the iMcV-Giga-MediaLinX are as follows:

PWR Glows green when powered.
1000 Glows green when functioning at 1000 Mbps.
100 Glows green when functioning at 100 Mbps.
10 Glows amber when functioning at 10 Mbps.
LNK/ACT

• Glows green when a link is established.

• Blinks green when data activity occurs.
(This is true for both LNK/ACT LEDs.)

FDX

• Glows amber when in Full-Duplex mode.

• Blinks amber when operating in Half-Duplex
mode and when collisions occur.

FA Glows green when FiberAlert is enabled.
TX LL Glows green when TX LinkLoss is enabled.
LNK/ACT

• Glows green when a link is established.

• Blinks green when data activity occurs.

MASTER Glows amber when in Master mode.

The twisted pair port on the iMcV-Giga-MediaLinX includes AutoCross, a
feature which automatically selects between a crossover workstation or
pass-through connection depending on the connected device.

Installing the iMcV-Giga-MediaLinX

The iMcV-Giga-MediaLinX installs in any IMC Networks chassis, each

requiring one slot.

To install a module, remove the blank brackets covering the slots where
the module is to be installed (if present) by removing the screws on the out­side edges of the bracket. Slide the 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 the configuration require­ments change.

INSTALLATION

TROUBLESHOOTING

• During installation, test the fiber and twisted pair connections with all

troubleshooting features disabled, then enable these features, if desired,
just before installation. This will reduce the features’ interference with
testing.

• Any testing of the module should be performed in an unmanaged envi-

ronment. Either test in an unmanaged chassis or disable management in
a managed chassis, where possible.

• LNK LEDs will only function after BOTH twisted pair and fiber connec-

tions have been established.

• If using a high powered device (for long distance installations) for a short

distance installation, the fiber transmitters may overdrive the receivers
and cause data loss. In such a case, add an optical attenuator to the
connection.

Configuring the iMcV-Giga-MediaLinX

The iMcV-Giga-MediaLinX may be configured with various features such
as LinkLoss, FiberAlert, Auto-Negotiation, duplex mode and speed. The fol­lowing sections include instructions for configuring both managed (via an
SNMP-compatible management application like iView²) and unmanaged
modules.

MANAGED MODULES

To manage an iMcV-Giga-MediaLinX, it must be installed within an
SNMP-Manageable chassis. In a managed environment, install the module
first, then configure using the management software. Within iView², con­figure features and troubleshooting functions in the Module Detail section
under the picture of the module. See the iView² online help file for more
information.

NOTE

Until a module installed in a managed chassis is configured via the software, the
module (and its LEDs) may not work properly.

UNMANAGED MODULES

Configure the iMcV-Giga-MediaLinX for desired features before installing it

inside a chassis.

Dip Switch Settings

S1 Function Default

1 TX Auto-Negotiation ON

2 TX Port: HDX(ON) or FDX(OFF) OFF
3 TX Port: 100(ON) or 10(OFF) OFF
4 TX Port: 1000 OFF
5 TX LinkLoss OFF
6 FiberAlert OFF
7 Selective Advertising OFF
8 Master (ON) or Slave (OFF) OFF
9 FX Negotiation OFF

AUTO-NEGOTIATION

10 Factory Configured – Do not change

The iMcV-Giga-MediaLinX ships from the factory with Auto-Negotiation
enabled on the twisted pair port. In this mode, the twisted pair port negotiates
for speed and duplex, autosensing 10 Mbps Full-Duplex, 10 Mbps Half-Duplex,
100 Mbps Full-Duplex, 100 Mbps Half-Duplex with Flow Control, 1000 Mbps
Full-Duplex or 1000 Mbps Half-Duplex with Flow Control. Configure Auto­Negotiation by setting the DIP switch (for unmanaged modules) or via the man­agement software.

SELECTIVE ADVERTISING

Selective Advertising, when used in combination with Auto-Negotiation,
advertises only the configured speed and duplex mode for the twisted pair port.
This allows configuration of both the twisted pair port’s speed (10, 100 or 1000
Mbps) and Duplex mode (FDX or HDX).

Selective Advertising (switch 7) functions only with Auto-Negotiation (switch

1) enabled.

Selective Advertising Configuration Chart

Desired Speed/Duplex Switch 3: Speed Switch 4: Speed Switch 2: Duplex

1000 Mbps FDX OFF ON OFF
1000 Mbps HDX OFF ON ON

100 Mbps FDX ON OFF OFF
100 Mbps HDX ON OFF ON
10 Mbps FDX OFF OFF OFF
10 Mbps HDX OFF OFF ON

F

ORCING THE DUPLEX MODE

The twisted pair port on the iMcV-Giga-MediaLinX can be set to either Half­or Full-Duplex operation. Before manually setting the duplex mode, disable
Auto-Negotiation by setting DIP Switch 1 to OFF.

• The twisted pair port is configured for Full-Duplex by default, which is the OFF

position on DIP Switch 2.

• Configure the twisted pair port for Half-Duplex by setting DIP Switch 2 to the

ON position.

FORCING THE S

PEED

The speed on the twisted pair port (10, 100, or 1000 Mbps) can also be man­ually configured. (The fiber port always operates at 1000 Mbps.) Before manu­ally setting the duplex mode, disable Auto-Negotiation by setting DIP Switch 1
to OFF.

• Configure the twisted pair port for 10 Mbps operation by setting both DIP

Switches 3 and 4 to the OFF position.

• Configure the twisted pair port for 100 Mbps operation by setting DIP

Switch 3 to the ON position and DIP Switch 4 to OFF.

• Configure the twisted pair port for 1000 Mbps operation by setting DIP

Switch 4 to the ON position. (When ON, Switch 4 overrides Switch 3).

FX NEGOTIATION

The iMcV-Giga-MediaLinX includes the FX Negotiation feature, which negotiates
duplex mode and also helps insure links. Disabled by default, it must enabled or dis­abled on both ends of the connection to establish a link. Only enable this feature if
the connecting device supports it.

MASTER/SLAVE MODE

The Master/Slave mode feature determines which clock will be used between
the iMcV-Giga-MediaLinX and the connected device. Slave mode is set by
default to use the clock of the connected device. Master mode uses the iMcV­Giga-MediaLinX's clock. The Master/Slave mode is only valid for the twisted pair
link and can only be manually configured. Configure Master mode by setting
Dip Switch 8 to the ON position.

FLOW CONTROL

Flow Control is used to throttle the END device to avoid dropping packets
during network congestion. Full-Duplex Flow Control will only function when
the END device has Flow Control and advertises in Full-Duplex Mode. Half­Duplex Flow Control does not Advertise.

About LinkLoss and FiberAlert

The iMcV-Giga-MediaLinX includes such troubleshooting features as
FiberAlert and TX LinkLoss, which can help locate "silent failures" on the network.
This section explains how FiberAlert and LinkLoss work, and how they will react
in a network configuration, which should be understood before attempting to
install the module(s).

ABOUT LINK INTEGRITY

During normal operation, link integrity pulses are transmitted by all
point-to-point Ethernet devices. When an iMcV-Giga-MediaLinX 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 iMcV-Giga-MediaLinX 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 I

S TX LINKLOSS?

TX LinkLoss is a troubleshooting feature. When 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 link on the device con­nected to the fiber port.

Enable TX LinkLoss by setting DIP Switch 5 to the ON position.

W

HAT IS

FIBERALERT?

FiberAlert is a troubleshooting feature that minimizes the problems asso­ciated with the loss of one strand of fiber. If a strand is unavailable, the
device at the receiver end notes the lost
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.

Enable FiberAlert by setting DIP Switch 6 to the ON position.

NOTE

Enable FiberAlert on ONE side of a media conversion only; Enabling it on
both sides would keep both transmitters off indefinitely.

Fiber Optic Cleaning Guidelines

Fiber optic equipment is extremely susceptible to contamination by particles
of dirt or dust which can obstruct the optics and cause performance degrada­tion. Good system performance requires clean optics and connector ferrules.

1) Only use fiber patch cords (or connectors) from a reputable supplier; low­quality components can cause many hard-to-diagnose problems.

2) IMC Networks installs dust caps to ensure factory-clean optical devices.
These protective caps should not be removed until the moment of con­necting the fiber cable to the device. Assure that the fiber is properly ter­minated, polished and free of any dust or dirt and that the location is as
free from dust and dirt as possible.

3) Store spare caps in a dust-free environment such as a sealed plastic bag or
box so reinstalled caps do not introduce any contamination to the optics.

4) Reinstall the protective caps when disconnecting the fiber device.

5) To clean contaminated optics, alternate between blasting with clean, dry,
compressed air and flushing with methanol to remove particles of dirt.
