Chapter 2: Overview
2. Overview
2.1 Introduction
The Compact Media Converter provides two conversions between
10/100/1000BASE-T twisted pair and 100/1000BASE-SX/FX fiber. This device
automatically negotiates speed and duplex on the copper port and the fiber
100/1000 Mbps, full-duplex port.
The Compact Media Converter, SFP (LGC5150A) is an SFP port-based model that
includes two 10/100/1000 Mbps RJ-45 connectors and one SFP port. It supports
MSA-compliant 1000- or 100-Mbps SFPs. A DIP switch enables LFPT (Link Fault
Passthrough), a diagnostic feature for troubleshooting a fault fiber. An SFP version
is available; both support jumbo frames up to 10240 MTU. The media converter
will detect the SFP and run over single-mode fiber or multimode fiber at the
speed for which the SFP was designed. Compatible SFPs include the
LFP401–LFP403 and LFP411–LFP414 (see Table 2-4).
The Compact Media Converter, TX/FX (LGC5151A) is a fixed fiber transceiver
model that includes two 10/100/100 Mbps RJ-45 connectors and one
1000-Mbps SC fiber connector. The LGC5151A supports dual-strand multi-mode
fiber. A DIP Switch enables LFPT (Link Fault Passthrough), a diagnostic
feature for troubleshooting a fault condition on a segment.
The Compact Media Converter, TX/FX (LGC5152A) is a fixed fiber transceiver
model that includes two 10/100/100 Mbps RJ-45 connectors and one
1000-Mbps SC fiber connector. The LGC5152A supports dual-strand single-mode
fiber. A DIP Switch enables LFPT (Link Fault Pass-Through), a diagnostic feature for
troubleshooting a fault condition on a segment.
2.2 Features
• All models have (2) 10/100/1000 Mbps copper ports.
• Specific models have (1) SFP port or fixed fiber port (single-mode or multimode).
• Compact, rugged device includes an internal AC power supply.
• Easy to install.
• Unmanaged device, requires no software installation.

4.1 Powering the Compact Media Converter
The Compact Media Converter is powered via an industry-standard IEC connector
and will support 100–240 VAC, 50/60 Hz, 7 Watts maximum working power.
Figure 4-1. Power connector.
4.2 LED Indicators
Each Compact Media Converter includes four top-panel and side-panel LEDs.

4.3 LFPT
The Compact Media Converter includes an LFPT DIP switch, located on the front
of the unit.

Table 4-3. LFPT DIP switch functions.
LFPT DIP Switch Position Description
Switch Up LFPT ON
Switch Down LFPT OFF
Link Fault Pass-Through (LFPT) is a troubleshooting feature that combines TX and
FX link loss from both the local and remote Compact Media Converter, TX-FX/SFP
modules. LFPT is enabled by turning on the DIP switch on both modules. This
feature allows either end of the conversion to detect a link fault occurring at the
other end of the media conversion chain. On the Compact Media Converter, LFPT
is supported on the connector closest to the DIP switch.
Link Fault Passthrough
Figure 4-5. LInk Fault Passthrough (LFPT) function.

Page 18 724-746-5500 | blackbox.com
Chapter 4: Operating the Compact Media Converter
Regardless if there is a break in segment 1, 2, or 3, the link will drop on the
switches at both ends. The link fault passes through the media converter and is
observed at each end. It acts just as it would if the devices were directly
connected.
NOTE: Dropping the link on the supported copper port will disable the fiber port.
This will break the connection from the other copper port to the fiber port.
4.4 Low SPD Switch on the LGC5150A
The SFP version of the Compact Media Converter (LGC5150A) supports a low-
speed (LOW SPD) DIP Switch. If a Gigabit SFP is installed in the SFP port and you
set the switch to the ON position, it will force the SFP to operate at 100 Mbps.
This DIP switch setting is available only on the LGC5150A model, on its fiber SFP
port.
The fixed fiber port models (LGC5151A and LGC5152A) do not have this DIP
switch.

Chapter 5: Maintenance
5. Maintenance
5.1 Fiber Optic Cleaning GuidelinesFiber 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. Do
not remove these protective caps until the moment you connect the fiber cable
to the device. If you need to 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.
5.2 Electrostatic Discharge (ESD)
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.

Page 20 724-746-5500 | blackbox.com
Chapter 5: Maintenance
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.
