EL900  EL900 Series Hardened Media Converter

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.

EL900

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

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 fails, 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.
