Introduction

Transition Networks M/GE-T Series is a Gigabit Ethernet stand-alone Mini media converter that provides cost effective
media conversion between 1000Base-T ports and 1000Base-SX/LX 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 1, the physical
layer, data is passed through the converter at line speed, making it ideal for applications where low latency is essential.

Installation

Observe ESD Precautions

Always observe the following ESD (Electrostatic Discharge) precautions when installing or handing the M/GE-T-xxx-01
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 system unit throughout any procedure requiring ESD protection.

Copper and Fiber Ports

The figure below shows the front panel of the M/GE-T-xxx-01 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 1000Base-X fiber cable with male, two-stranded TX to RX connectors installed
at both ends.

2. Connect the fiber cable to the M/GE-T-xxx-01 media converters 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 (another 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.

1. Locate or build IEEE 803.2™ compliant 10/100/1000Base-T cables 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/GE-T-xxx-01 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.).

Note: With Fiber Link Pass Through permanently enabled, the copper Link LED only lights when there is a valid fiber link
on the converter.

Power up the Media Converter

Power Supply Included: To order the corresponding country specific power supply, add the extension from the list
below to the end of the SKU (-NA = North America, -LA = Latin America, -EU = Europe, -UK = United Kingdom, -SA =
South Africa, -JP = Japan, -OZ = Australia, -BR = Brazil).

The M/GE-T-xxx-01 media converter is powered by using a DC power adapter through the barrel connector on its rear
panel, as shown below.

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 that the front panel LED power (PWR) indicator is lit.

DC Power

Consult the user guide for the Transition Networks SPS-2460-SA DC external power supply for powering the media
converter.

Features

Auto-Negotiation

The M/GE-T-xxx-01 Auto-Negotiation feature is permanently enabled. Auto-Negotiation allows the media converter to
configure itself automatically to achieve the best possible mode of operation over a link. It broadcasts speed (1000
Mb/s) and duplex capabilities (full) 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.

Auto MDI / MDI-X

The AutoCross feature allows using either straight-through (MDI) or crossover (MDI-X) copper cables. 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 a switch if the link is lost, even with
Auto-Negotiation and Link Pass-through (both directions) enabled.

Fiber Link Pass Through (Fiber port only)

Link Pass Through is a troubleshooting feature that prevents media converters from isolating link failures and it allows
end devices to be notified in the event of a loss of link. Link Pass Through provides the media converter with the ability
to monitor both the fiber and the copper RX ports for a loss of signal. If a loss of RX signal occurs on one media port, the
converter will automatically disable the TX signal on the other port. By shutting down the fiber TX port, the link failure is
“passed through” to the remote converter and device. The end device automatically notified of link loss, which prevents
loss of valuable data unknowingly transmitted over an invalid link.

Cable Specifications

The physical characteristics must meet or exceed IEEE 802.3™ specifications. Specs may vary between suppliers.

Troubleshooting

If the media converter fails, isolate and correct the failure by determining the answers to the following questions and then taking the
indicated action:

1. Is the power LED illuminated and did the TX and FX LEDs turn ON then turn OFF?

NO

• Is the power adapter the proper type of voltage and cycle frequency for the AC outlet?

• Is the power adapter properly installed in the media converter and in the outlet?

• Contact TN Tech Support: See Contact Us on page 9.

YES

• Proceed to step 2.

Note the following:

• As a link pass-through device both copper and fiber cables must be installed before the LEDs will light.

2. Are the “FX – Link” and “TX-Link/Act” LEDs lit on the RJ-45 port?

NO

• Check the copper cables for proper connection.

• Check the fiber cables for proper connection.

• Contact Technical Support: See Contact Us on page 9.

YES

• Contact Technical Support: See Contact Us on page 9.
