Chapter 2: Overview
2. Overview
2.1 Introduction
The MultiPower Miniature Media Converter links 10-, 100-, or 1000-Mbps
segments to fiber cabling. An SFP port enables you to use an SFP to link the
converter to many kinds of fiber cable: dual-strand available in LC connectors, and
single-strand fiber SFPs available in SC connectors. The fiber port always operates at
1000 Mbps full duplex; the copper port autonegotiates the connected device’s
speed and duplex mode: 10 Mbps, 100 Mbps, or 1000 Mbps, and half-duplex or
full-duplex (including flow control).
The SFP slot requires an SFP module, with or without DDMI (sold separately). SFPs
must be MSA-compliant and meet the Class 1 Laser Safety Standard.
Choose from multimode and single-mode SFPs. With a single-mode SFP, the media
converter supports distances up to 40 kilometers (24.8 mi.), even 70 kilometers
(43.5 mi.), depending on the model you order.
For extra versatility, you can power the Multipower Miniature Media Converter one
of three ways: through the external AC power supply included with each converter,
through the optional USB Power Adapter Cable (which plugs into a PC's USB port
and is sold separately), or through the optional rackmount PowerTray (sold
separately). The PowerTray provides power for up to 18 converters in only 5U of rack
space. Rackmount ears are included.
2.2 Features
• Connect Ethernet, Fast Ethernet, or Gigabit Ethernet copper ports to fiber optic
cable.
• Autosensing copper ports make them perfect for migrating networks.
• Accepts 1250-Mbps SFPs.
• Use as standalone media converters or rackmount in the optional PowerTray.
• Powered by its universal AC power supply, a PC's USB port, or the optional
rackmountable PowerTray.
• Auto MDI/MDI-X means you never need to worry about what kind of cable to
use.
• Easy to install. Just plug and play.
• Compact size.
• Uses inexpensive CAT5e twisted-pair cable on the copper side.
• Offers Link Fault Pass-Through (LFPT).

Chapter 3: Installation and Operation
3. Installation and Operation
3.1 Installing the MultiPower Miniature Media Converter
The LGC135A installs in a PowerTray or can be used as a standalone media
converter. As a standalone, the converter uses a universal external switching power
cube with 100–240 ±10% VAC input and 5 VDC output.
3.2 Powering the Media Converter
The LGC135A includes multiple powering options:
• A country-specific, high-reliability AC power adapter (included)
• PowerTray (ordered separately) for rackmounting
3.3 LED Operation
Each media converter includes two LEDs, located on the RJ-45 connector
(see Figure 2-1).
Table 3-1. LED indicators.
LED Description
TX LNK/ACT Glows green when a link is established on the fiber port.
Blinks green when activity is detected on the fiber port.
RX LNK/ACT Glows amber when a link is established on the copper port.
Blinks amber when activity is detected on the copper port.

Appendix
Appendix. Fiber Optic Cleaning Guidelines and Electrostatic
Discharge Precautions
A.1 Fiber Optic Cleaning Guidelines
Fiber optic transmitters and receivers are extremely susceptible to contamination by
particles of dirt or dust, which can obstruct the optic path and cause performance
degradation. Good system performance requires clean optics and connector
ferrules.
1. Use fiber patch cords (or connectors, if you terminate your own fiber) only from a
reputable supplier; low-quality components can cause many hard-to-diagnose
problems in an installation.
2. Dust caps are installed at Black Box to ensure factory-clean optical devices. These
protective caps should not be removed until the moment of connecting the fiber
cable to the device. If you disconnect the fiber device, reinstall the protective dust
caps.
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. 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.
A.2 Electrostatic Discharge Precautions
Electrostatic discharge (ESD) can cause damage to any product, add-in modules, or
standalone units containing electronic components. Always observe the following
precautions when installing or handling these kinds of products:
1. Do not remove unit from its protective packaging until ready to install.
2. Wear an ESD wrist grounding strap before handling any module or component. If
the wrist strap is not available, maintain grounded contact with the system unit
throughout any procedure requiring ESD protection.
3. Hold the units by the edges; 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 modules or standalone units over
any surface.
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.
