Introduction
Thank you for choosing the Metrobility 2131 media converter.
Metrobility 2131 media converters represent the hottest technology available for
extending Ethernet and Fast Ethernet networks. Since Metrobility first developed
“twister” media conversion, it has become a standard for providing a cost-effective
means of integrating a mixed media environment. As LANs grow and evolve, this
technology provides an ideal solution for building effective migration strategies.
These IEEE 802.3u compliant media converters are compatible with Fast Ethernet
devices from other leading network technology providers. This increases the flexibility of your network configuration by ensuring reliable data transmission in multivendor as well as mixed media environments.
The information in this guide will help you to install and start using your 2131 media
converter.

Overview
The Metrobility 2131 100Mbps TX-to-FX media converter provides seamless
high-speed integration of 100BASE-TX twisted-pair and 100BASE-FX fiber optic
segments in Fast Ethernet environments. The 2131 supports remote fiber optic links
up to 2km over multimode and up to 100km over singlemode fiber optic cable.
To optimize your Fast Ethernet network, this innovative media converter provides
seamless operation in half-duplex or full-duplex environments. Full signal restoration —with a low bit delay — ensures accurate data transmission to and from LANs
within an organization. All signal activity is completely converted ensuring accurate
communication and collision detection in connected segments and allowing maximum media length to be achieved on either side of the device.
The Metrobility 2131 provides the following key features:
• A Link Loss Carry Forward (LLCF) enable/disable switch is included
to provide an easy means for troubleshooting a remote network
connection. Refer to the section of this guide titled “Link Loss Carry
Forward” for more information.
• All twisted-pair ports are equipped with an MDI-II to MDI-X switch
eliminating the need for crossover cables.
• Auto polarity support on all twisted-pair ports.
Whether you are updating or expanding your existing network, the Metrobility line
of media converters supports a wide range of configuration needs. The 2131 includes
the following media conversion combinations:
2131-13-01 TX to FX multimode SC
2131-14-01 TX to FX singlemode SC
2131-15-01 TX to FX multimode ST
2131-16-01 TX to FX singlemode ST
2131-17-01 TX to FX singlemode SC (40km)
2131-1J-01 TX to FX singlemode SC (100km)
2131-1X-01 TX to FX singlemode 1550/1310nm BWDM SC
2131-1Y-01 TX to FX singlemode 1310/1550nm BWDM SC

Installation Guide
Follow the simple steps outlined in this section of the guide to install and start
using your Metrobility 2131 media converter.
Unpack the “twister” Media Converter and Accessories
Check that the following components have been included with your order:
1
2
• 2131 media converter
• Power supply
• Power cord
• Four (4) rubber feet
Your order has been provided with the safest possible packaging, but
shipping damage does occasionally occur. Inspect your order carefully. If
you discover any shipping damage, notify the carrier and follow their
instructions for damage and claims. Save the original shipping carton if
return or storage of the unit is necessary.
Choose an Appropriate Location
The 2131 media converter is intended for use in either office or industrial
environments. The unit must be located within six (6) feet of the AC power
source being used and placed as far away as possible from electrical noise
generating equipment such as copiers, electrostatic printers and other
motorized equipment. If exposed twisted-pair wiring is used nearby, the
wiring should be routed as far away as possible from power cords and data
cables to minimize interference.
The units may be oriented in any manner which permits you to make
physical connection to the power supply and leaves a minimum of six (6)
inches of space for proper ventilation.
TUV Compliance Note: For pluggable equipment, the socket outlet must be
installed near the equipment and be easily accessible.
Bei Geräten mit Steckanschluß muß die Steckdose nahe dem Gerät
angebracht und leicht zugänglich sein.
