Introduction
EL1142 Hardened Media Converter
2-port 10/100BASE-TX + 2-port 100BASE FX MM (SC)- 2km
2-port 10/100BASE-TX + 2-port 100BASE FX SM (SC)- 40km
The EL1142 series provides two independent media conversion paths between 2 x 10/100BASE-T and
2 x 100BASE-SX-LX fiber. Similar to the EL1141 series media converter, the EL1142 includes the
hardened construction and high performance needed for mission critical applications, including power
substation automation. However, the EL1142 series offers twice the port density in the same housing
dimensions, providing greater flexibility and requiring less space for installation.

Unpacking
Open the carton and unpack the items. Your package should include an EL1142 media converter, this
Quick Install Guide, and a CD containing the user’s manual. If items are missing or damaged, notify
your EtherWAN representative.
Select Installation Location
Installation is DIN-rail, panel or rack mounting. Ensure that the power source is within 6 feet (1.8
meters), and check that there is adequate airflow.
Place the media converter on the DIN rail from above using the slot. Push the front of the media
converter toward the mounting surface until it audibly snaps into place.
Startup: Connect the supply voltage to start up the media converter via the terminal block.
Dismantling: Pull out the lower edge and then remove the media converter from the DIN rail.

EL1142 Hardened Media Converter
Connect Power
The media converter is equipped with an eight-contact terminal block. The terminal block provides dual
DC power inputs, and arelayoutput contact. Redundant power supplyis supported, but only onepower
input is required for operation. Note that the media converter does not have a power switch; it is turned
on/off by connecting/disconnecting power.
Input voltage is 12 to 48VDC.
The power dissipation under full load is as follows:
12V/0.4A, 24V/0.19A, 48V/0.11A
Note: Use qualified power supply by SELV or double
insulation of UL 60950 or UL 61010-1 or UL 61010-2-201 standards.
Insert the DC input wires into the corresponding terminals, and tighten the clamp screws to hold them in
place. Make sure that the plastic terminal block connector prongs are plugged firmly into the terminal
block receptacles.
Power wiring information:
Use cable type - AWG (American Wire Gauge) 18-24 and the corresponding pin type cable terminals.
Use torque value 1.7 lb-in, do not use excessive force when fixing wiring.
The wire rating must be at least 105°C
Label clean up:
Indoor use and pollution degree II, it must be wiped with a dry cloth for clean up the labelling.
If the equipment is used in a manner not specified by the manufacturer, the protection provided by the
equipment may be impaired.
The media converter shall be mounted in an industrial control panel and ambient temperature is not
exceed 75 degree C.
Altitude up to 2000 meters.
Humidity range (Operational): 5% to 95%, non-condensation.
The product is open type.
The product is for indoor use.

DIP Switches
Port, power and LFPT settings are made very simple by means of two sets of six DIP (Dual Inline
Package) switches on the top panel of the hardened media converter. Default position for all DIP
switches is ‘0’.

* LFPT=Link Fault Pass Through
If Force mode is enabled, the media converter must be restarted in
order for the new setting to take effect.
Link Fault Pass Through (LFPT)
LFPT (Link Fault Pass Through) is a feature that will pass a link fault through the device at each
segment. If either of the copper TX links fail, the media converter will pass the fail state on throughout
the link, taking down the middle fiber as well as the copper link on the opposite end. This prevents the
connected switches from sending packets that would end up lost. LFTP is designed for use with media
converters arranged in pairs, and both devices must support LFPT.

Relay Output Alarm
The media converter is equipped with relay output contacts on the terminal block for signaling of a
power or port failure. The relay output can be connected to an alarm signaling device. Current is 0.6A
@ 30VDC. Default is PW1 and PW2 both off and points 2 & 3 open.
