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.

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:
4. Connect the male TX cable connector to the female RX port.
5. 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.

M/E-PSW-FX-02 Back Panel Power

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 the 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.

• FX-Link/Act (Fiber Link/Activity): (Upper Left on RJ-45)
• ON = Link; Flashing = Activity
• TX-Link/Act (Copper Link/Activity): (Upper Right on RJ-45)
• ON = Link; Flashing = Activity

Product Features

• Feature Summary – M/E-PSW-FX-02

Auto-Negotiation| AutoCross| Link Pass-Through (LPT)| Far End Fault
---|---|---|---
Yes| Yes| No| Yes

Congestion Reduction

• The M/E-PSW-FX-02 media converters do not forward collision signals or error packets from one collision domain to another, resulting in improvements in baseline network performance.
• In addition, the media converter filters packets destined for local devices, which reduces network congestion.

Auto-Negotiation

• The Auto-Negotiation feature is ON permanently for the M/E-PSW-FX-02 media converters. Auto-negotiation allows the media converter to configure itself automatically to achieve the best possible mode of operation over a link. It broadcasts speed (10 Mb/s or 100 Mb/s) and duplex capabilities (full or half) to the other device and negotiates the best mode of operation. Auto-negotiation allows quick and easy installation because the optimal link is established automatically.
• In a scenario where an auto-negotiation device is linked to a non-negotiating device, the negotiating device via parallel detection recognizes the speed of that second device and then establishes the best operating speed (10Mb/s or 100Mb/s) at half-duplex.

AutoCross™

• The AutoCross feature allows the use of either straight-through (MDI) or crossover (MDI-X) copper cables when connecting to 10Base-T or 100Base-TX devices. AutoCross determines the characteristics of the connection and automatically configures the device to link up, regardless of the copper cable configuration, MDI or MDI-X.

Automatic Link Restoration

• The media converter will automatically re-establish the link when connected to switches if the link is lost, even with Auto-Negotiation and Link Pass-through (both directions) enabled.

Full-Duplex Flow Control

• In a full-duplex network, maximum cable lengths are determined by the type of cables used. The 512-bit Rule does not apply in a full-duplex network. Note: Full duplex is ON permanently for the fiber port only.

Half-Duplex Flow Control (512-Bit Rule)

• In a half-duplex network, the maximum cable lengths are determined by the round-trip delay limitations of each Fast Ethernet collision domain. (A collision domain is the longest path between any two terminal devices; e.g., a terminal, switch, or router.) The 512-bit Rule determines the maximum length of cable permitted by calculating the round-trip delay in bit-times (BT) of a particular collision domain. If the result is less than or equal to 512 BT, the path is good.

Flow Control

• The process of adjusting the flow of data from one device to another ensures that the receiving device can handle all the incoming data. This is particularly important where the sending device is capable of transmitting data much faster than the receiving device can accept it.

Distance Extension

• The M/E-PSW-FX-02 media converters can segment one (1) 10Base-T copper Ethernet and/or 100Base-TX copper Fast Ethernet, and one (1)100Base-FX fiber Fast Ethernet collision domain:
• In a half-duplex Ethernet or Fast Ethernet environment, the M/E-PSW-FX-02 media converters extend network distances by segmenting collision domains so that the 512-bit Rule applies separately to each collision domain.
• In a full-duplex Ethernet or Fast Ethernet environment, the M/E-PSW-FX-02 media converters extend network distances to the physical cable limitations imposed by the selected twisted-pair copper fiber cables.

Rate Conversion

The M/E-PSW-FX-02 media converters allow connection of 10Mb/s terminal devices on a 10Base-T legacy Ethernet copper network to 100Mb/s terminal devices on a 100Base-TX Fast Ethernet copper network and/or to 100Mb/s terminal devices on a 100Base-FX Fast Ethernet fiber network.
Far-End Fault
When a fault occurs on an incoming fiber link (1), the media converter transmits a Far-End Fault signal on the outgoing fiber link (2). In addition, the Far-End Fault signal also activates the Link Pass-Through, which in turn, disables the link on the copper portion of the network (3) and (4).
