Always observe the following ESD precautions when installing or handing the

M/GE-PSW-xX-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.

Installation -- Continued

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-PSW-xX-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.

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-PSW-xX-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.).

Product features

Congestion reduction

The M/GE-PSW-xX-01 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 also.

Auto-Negotiation

The Auto-Negotiation feature is ON permanently for the M/GE-PSW-xX-01 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 /100/1000 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 then establishes the best operating speed (10/100/100Mbs) at half-duplex.

AutoCross™

The AutoCross feature allows using 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.

Link Pass-Through

The Link Pass-Through feature (illustrated below) allows the media converter to

monitor both the fiber and copper RX (receive) ports for loss of signal. In the event

of an RX signal loss (1), the media converter will automatically disable the TX

(transmit) signal (2), thus “passing through” the link loss (3). The far-end device is

automatically notified of the link loss (4), which prevents the loss of valuable data

unknowingly transmitted over an invalid link.

Note: Both copper and fiber cables must be installed before the LEDs will light.

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—see page 1 (front cover) for M/GE-PSW-xX-01 cable specifications.

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.

For more information on the 512-Bit Rule, see the white paper titled “Collision

Domains” on the Transition Networks website at: www.transition.com

Back pressure

Back pressure is used in half duplex mode. It ensures the retransmission of

incoming packets when a port using half-duplex is temporarily unable to receive

incoming frames.

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/GE-PSW-xX-01 media converters can segment one (1) 10Base-T copper

Ethernet, 100Base-T copper fast Ethernet, or 1000Base-T copper Gigabit Ethernet,

and one (1)1000 Base-X fiber Fast Ethernet collision domain:

In a half-duplex Ethernet or Fast Ethernet environment, the M/GE-PSW-xX-01

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/GE-PSW-xX-01

media converters extend network distances to the physical cable limitations

imposed by the selected twisted-pair copper fiber cables.

Rate conversion

The M/GE-PSW-xX-01 media converters allow the following connections:

• 10Mb/s devices on a 10Base-T legacy copper network to 1000Mb/s devices on

a 1000Base SX/LX Gigabit Ethernet fiber network.

• 100Mb/s devices on a 100Base-T legacy copper network to 1000Mb/s devices

on a 1000Base SX/LX Gigabit Ethernet fiber network.

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?

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 Technical Support: US/Canada: 1-800-260-1312, International:

00-1-952-941-7600.

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 “TX and FX-Link/ACT” LEDs illuminated on the RJ-45 port ?

• Check the copper cables for proper connection.

• Check the fiber cables for proper connection.

• Contact Technical Support: US/Canada: 1-800-260-1312, International:
