1 Introduction
Product Description
The M/E-PSW Series is a Fast Ethernet stand-alone Mini media converter that provides cost effective
media conversion between 10/100Base-TX ports and 100Base-FX ports. With its fixed configuration,
deployments are just plug-and-play, and its small size makes it ideal for locations where space is limited.
Operating at Layer 2, the data link layer, this converter not only converts copper to fiber, it also provides
rate conversion allowing legacy 10Base-T copper devices to connect to 100Base-FX fiber.

Lifetime
* MTBF (Mean Time Between Failure) is estimated using the predictability method. The computation is
based on the MIL-HDBK-217 F and Bellcore standards.
**Manufacturer’s rated ambient temperature.
WARNING: If the media converter is an IEEE802.3-2005 Powered Device (PD) capable of receiving
power via the Media Dependent Interface (MDI) leads, the power source, connector, and cable attached
to the barrel power connector must meet the isolation requirement specified in IEEE802.3-2005. Failure to
observe this warning could result in an electrical shock.

CAUTION: Copper based media ports, e.g., Twisted Pair (TP) Ethernet, USB, RS232, RS422, RS485,
DS1, DS3, Video Coax, etc., are intended to be connected to intra- building (inside plant) link segments
that are not subject to lightening transients or power faults. Copper-based media ports, e.g., Twisted Pair
(TP) Ethernet, USB, RS232, RS422, RS485, DS1, DS3, Video Coax, etc., are NOT to be connected to
inter- building (outside plant) link segments that are subject to lightening transients or power faults. Failure
to observe this caution could result in damage to equipment.
WARNING: Visible and invisible laser radiation when open. Do not stare into the beam or view directly
with optical instruments. Failure to observe this warning could result in an eye injury or blindness.
WARNING: Use of controls, adjustments, or the performance of procedures other than those specified
herein could result in hazardous radiation exposure.

2 Installation
Checklist
Before installing the N-FXE Series NIC, verify that the package contains these items:
•One N-FXE Series NIC
•A Product Post Card
Please notify your sales representative immediately if any of these items is missing or damaged.
Power Supply Included
To order the corresponding country specific power supply, add the extension to the end of the SKU.
For example, M/E-PSW-FX-02-NA = North America, -LA = Latin America, -EU = Europe, -UK = United
Kingdom, -SA = South Africa, -JP = Japan, -OZ = Australia, -BR = Brazil.
Electrostatic Discharge (ESD)
Always observe the following ESD precautions when installing or handing the M/E-PSW-FX-02
•Do not remove the converter from its protective packaging until you are ready to
install it.
•Wear an ESD wrist grounding strap before handling any module or component. If you do not have a
wrist strap, maintain grounded contact with the unit throughout
any procedure requiring ESD
protection.
Copper and Fiber Ports
The illustration below shows the front panel of the M/E-PSW-FX-02 media converters.

Connect the Fiber Cable
Full duplex (always ON) is on the fiber side only, therefore, the 512-Bit Rule does not apply. The cable
lengths are constrained by the cable requirement.
1. Locate or build IEEE 803.2 compliant 100Base-FX fiber cable with male, two- stranded TX to RX
connectors installed at both ends.
2. Connect the fiber cable to the M/E-PSW-FX-02 media converter as follows:
•Connect the male TX cable connector to the female TX port.
•Connect the male RX cable connector to the female RX port.
3. Connect the fiber cable to the other device (media converter, hub, etc.) as follows:
•Connect the male TX cable connector to the female RX port.
•Connect the male RX cable connector to the female TX port.
Connect the Twisted-pair Copper Cable
The AutoCross feature allows either MDI (straight-through) or MDI-X (crossover) cable connections to be
configured automatically, according to network conditions.
•If half-duplex mode is used, refer to the 512-Bit Rule.
•If full-duplex mode is used, the 512-Bit Rule does not apply. The cable lengths are constrained
by the cable requirements.
1. Locate or build IEEE 803.2™ compliant 10Base-T or 100Base-TX cable, with RJ-45 connectors
installed at both ends.
2. Connect the RJ-45 connector at one end of the cable to the RJ-45 port on the M/E-PSW-FX-02.
3. Connect the RJ-45 connector at the other end of the cable to the RJ-45 port on the other device
(switch, workstation, etc.).

Powering the Media Converter
The power options for the M/E-PSW-FX-02 media converter are product dependent. The following shows
the various power configurations associated with each model.

Power Adapter
AC Power
1. Connect the barrel connector of the power adapter to the media converter’s power port (located on
the back panel of the media converter).
2. Connect the power adapter plug to AC power.
3. Verify that the media converter is powered up by observing the illuminated LED power indicator
light on the front panel.
DC Power
See the Lantronix SPS-1872-SA DC User Guide for the external power supply for powering the media
converter.
