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.

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).

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.

WARNING

Integrated circuits and fiber optic components are extremely susceptible to electro­static discharge damage. Only qualified service technicians using tools and tech­niques comforming to accepted industry practices should handle these components.
