Installation
Copper and fiber ports
The illustration below shows the front panel of the M/E-PSW-FX-02 media converters.
Electrostatic Discharge (ESD)
Always observe the following ESD precautions when installing or handing the M/E-PSW-FX-02 media
converter:
• 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
ESD protection.
any procedure requiring
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 coppe r 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
by the cable requirements.
1. Locate or build IEEE 803.2™ compliant 10Base-T or 100Base-TX cable, with
connectors installed at both ends.
2. Connect the RJ-45 connector at one end of the cable to the RJ-45 port on the
02 media converter.
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.).
