Introduction
EL900 Hardened Media Converter
10/100BASE-TX to 100BASE-FX
This hardened media converter provides an affordable solution for rugged and outdoor environment,
transportation road-side cabinet, industrial floor shop, multitenant dwellings or Fiber To The Home
(FTTH) applications. Capable of operating at temperature extremes of -40°C to +75°C, this is the
media converter of choice for harsh environments constrained by space.
Plug-and-Play Solution:
The hardened media converter is a plug-and-play media converter in compact size. It doesn't require
any complicated software to set up.

Unpacking
Open the carton and unpack the items. Your package should include an EL900 media converter, an
AC to DC power adaptor and cable (optional) and a Quick Install Guide. If items are missing or
damaged, notify your EtherWAN representative.
Select Installation Location
Installation is DIN rail-mount, or wall mount (in an enclosure or industrial panel).
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.

Connect Power
The media converter is equipped with an six-contact DC terminal block. The terminal block provides
dual DC power inputs, and a relay output contact. Redundant power supply is supported, but only one
power 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 10 to 48VDC.

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.
