About Media Converters

The modular Media Converter Series includes
modules that convert copper to single-mode,
multi-mode or single-strand fiber at Ethernet, Fast
Ethernet and Gigabit Ethernet speeds, and mod­ules that convert copper to thin coax at Ethernet
speeds. Modules install in a variety of chassis.

Media Converter Chassis

NOTE: All modules support half- and full-duplex.

10/100 Mbps Switching Media Conversion Modules

The auto-negotiating, 10/100 switching media converter offers plug-and-play
operation, converting 10Base-T or 100Base-TX, Half- or Full-Duplex twisted pair to
100Base-FX, Full-Duplex fiber. This module protects against Broadcast storms, and
allows jumbo packets of up to 1916 bytes. The following versions are available:

Configuring Media Conversion Modules

Before installing, you can configure 10Mbps and 100Mbps Modules for
a variety of features (see diagrams/chart on page 3-4 for specific informa­tion). 10/100 Switching and Gigabit Modules have plug-and-play operation
and require no configuration.

I NTERFERENCE

S TATEMENT

This equipment has been tested and found to comply with the limits for a Class A 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 A limits for radio noise emission from
digital apparatus set out in the Radio Interference Regulation of the Canadian Department of
Communications.

Le présent appareil numérique n’émet pas de bruits radioélectriques dépassant les limites
applicables aux appareils numériques de classe B prescrites dans le Règlement sur le brouil­lage radioélectrique publié par le ministère des Communications du Canada.

2) Black Box 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
that when reinstalled they do not introduce any contamination to the optics.

4) Should it be necessary to disconnect the fiber device, reinstall the protective dust
caps.

5) 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.

E LECTROSTATIC D

ISCHARGE P RECAUTIONS

Electrostatic discharge (ESD) can cause damage to your add-in modules. Always observe the

following precautions when installing or handling an add-in module or any board assembly

.

1) Do not remove unit from its protective packaging until you’re ready to install it.

2) Wear an ESD wrist grounding strap before handling any module or component. If
you do not have a wrist strap, maintain grounded contact with the system unit
throughout any procedure requiring ESD protection.

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.

3) Hold boards by the edges only; 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 board over any surface

.

NOTE

To determine which board diagram (-20, -40, -50, etc.) matches your module, compare the jumper
locations with the diagrams found above. 10/100 Switching modules and Gigabit modules do not
require any configuration, therefore the boards for those modules are not shown above.
