Chapter 2: Overview
2. Overview: About the Multi-Power Miniature Media Converter
10/100/1000
The Multi-Power Miniature Media Converter 10/100/1000 Auto Negotiating
switching miniature media converter. The fiber port always operates at 1000
Mbps Full Duplex; the copper port Auto negotiates the connected device’s
speed and duplex mode; 10/100/1000 Mbps Half Duplex; or 10/100/1000
Mbps Full Duplex (including Flow Control). The Multi-Power Miniature Media
Converter 10/100/1000 supports jumbo packets up to 1632 bytes.
The IE represents the unit’s use as an Industrial Ethernet device, which
allows for extended temperature operation of -25°F to +85°F (-10°C to
+50°C) when using the included AC adapter.
The Multi-Power Miniature Media Converter 10/100/1000 offers plug-andplay operation, including the AutoCross feature which automatically selects
between a crossover workstation and straight-through repeater hub
connection depending on the connected device.
The Multi-Power Miniature Media Converter 10/100/1000 can use either the
included Black Box universal, external power adapter with 100 to 240 ±10%
VAC input, or can be wired directly to the 7 to 50 VDC terminal block (for
extended temperature configuration). There is an optional Power Tray 18Slot AC for Miniature Converters in which up to 18 Multi-Power Miniature
Media Converters can be installed. When installing the Multi-Power
Miniature Media Converter 10/100/1000 in an 18 slot tray or using DC power,
the temperature range supported is -13°F to +185°F (-25°F to +85°F).

10/100/1000
3. Install the Multi-Power Miniature Media Converter 10/100/1000
Multi-Power Miniature Media Converter 10/100/1000 installs virtually
anywhere: as a standalone device. Installation options include:
• Velcro strips
• DIN rail mounting with DIN Rail clips
• A PowerTray/18 for high density applications
NOTE
Several models of the Multi-Power Miniature Media Converter 10/100/1000 support
single-strand fiber for operation. Since single-strand fiber products use optics that
transmit and receive on two different wavelengths, single-strand fiber products must
be deployed in pairs. For example, connect a Multi-Power Miniature Media Converter
10/100/1000, TX/SSLX-SM1310-SC (which has 1310 xmt and 1550 rcv) to a product
which has 1550 xmt and 1310 rcv, e.g. Hig h Densit y Media Converter System II Layer
1 Modules, TX/SSLX-SM1550-SC. The two connected products must also have the
same speed and distance capabilities (i.e. both are single-mode [20km] or both are
single/PLUS [40km]).
3.1 Powering the Multi-Power Miniature Media Converter 10/100/1000
Multi-Power Miniature Media Converter 10/100/1000 supports multiple
powering options.
• A country-specific AC power adapter (included)
• The 4-terminal DC power block
• Power Tray 18-Slot AC for Miniature Converters
• Dual USB cable
• IE-Power/5V DIN rail mount power supply
3.1.1 DC Terminal Block Wiring Instructions
The Multi-Power Miniature Media Converter 10/100/1000 can be powered via
the DC terminal block. From a power source, connect to any one positive
and any one negative terminal on the Multi-Power Miniature Media Converter
10/100/1000.

Chapter 3: Install the Multi-Power Miniature Media Converter
10/100/1000
Connected to Chassis
NOTE
When using stranded wire, the leads must be tinned and equivalent to a 16 AWG solid
conductor. The DC terminal block is protected against mis-wiring. If the unit is miswired, positive power lead to the negative terminal and negative power lead to the
positive terminal, it will not function. When powering a unit with voltages near the
upper limit of the device’s specification (for example: 48 volts) take precautions to limit
the voltage at the units termin al bl ock. When tur nin g on h i g h volta ge DC circuit s, initial
voltages may momentarily exceed the unit’s specification.
3.2 DIN Rail Mounting
The Multi-Power Miniature Media Converter
10/100/1000 ships from the factory with DIN clips,
allowing installation on a DIN rail. The Multi-Power
Miniature Media Converter 10/100/1000 mounts
perpendicular to the DIN rail (as shown).
Use the supplied screws to attach the DIN clips to
the Multi-Power Miniature Media Converter
10/100/1000, then snap the converter to the DIN
rail.
To remove the converter from the DIN rail, use a
flat-head screwdriver in the slot to gently pry the
converter from the rail.
NOTE
The DIN clips are designed for use on a DIN-35 rail.

3.3 Cascading Power
When installing multiple
Multi-Power Miniature
Media Converter
10/100/1000 units on a
DIN rail, connect to one
DC input source and then
cascade from one DC
block to the next, until
reaching the maximum
electrical current available.
3.4 DC Power Supply Precautions
The following precautions should be observed when installing chassis with
DC power supplies.
1. Check nameplate ratings to assure there is no overloading of supply
circuits that could have an effect on overcurrent protection and supply
wiring.
2. When installing 7 to 50VDC rated equipment, it must be installed only
per the following conditions:
a. Connect the equipment to a 7 to 50VDC supply source that is
electrically isolated form the alternating current source. The 7 to 50V
DC source must be connected to a 7 to 50VDC SELV source.
b. The maximum terminal voltage is 50VDC.
c. Input wiring to terminal block must be routed and secured in such a
manner that it is protected from damage and stress. Do not route
wiring past sharp edges or moving parts.
d. A readily accessible disconnect device, with a 3mm minimum
contact gap, shall be incorporated in the fixed wiring.
3. Grounding: reliable grounding of this equipment must be maintained.
Particular attention should be given to supply connections when
connecting to power strips, rather than direct connections to the branch
circuit. The Negative Terminal is common to the grounded case.

4. Operation
4.1 LED Operation
Each Multi-Power Miniature Media Converter 10/100/1000 includes two
LEDs, located on the RJ-45 connector. LED functions are as follows:
FX LNK/ACT Glows green when a link is established on the fiber port;
blinks green when activity is detected on the fiber port.
TX LNK/ACT Glows amber when a l i nk is established on the copper port;
blinks amber when activity is detected on the copper port.

Chapter 6: Fiber Optic Cleaning Guidelines
6. Fiber Optic Cleaning Guidelines
Fiber Optic transmitters and receivers are extremely sus ceptible to
contamination by particles of dirt or dust, which can obstruct the optic path
and cause performance degradation. Good s y stem 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-todiagnose problems in an installation.
2. Dust caps are installed at Black Bo x to ensure factory-cl ean optical devices.
These protective caps should not be removed u ntil the moment of connec ting
the fiber cable to the device. If you need to disconnect the fiber device,
reinstall the protective dust caps.
3. Store spar e c a ps i n a dust- f ree env ironment 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.

Chapter 7: Electrostatic Discharge Precautions
7. Electrostatic Discharge Precautions
Electrostatic discharge (ESD) can cause damage to any product, add-in
modules or stand alone 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 stand alone
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.
