Far-End Fault (always enabled)

This troubleshooting feature generally used in conjunction with Link Pass Through to notify both end devices of a link loss. If the fiber RX signal is lost on the far end converter, the converter will automatically generate a far-end fault signal and send it on its TX fiber port to notify the near-end converter of the fiber link loss. Link Pass-Through will then disable the copper link on both ends, alerting both end devices of network trouble. See diagram below.

	Device	4	Converter A	2	Converter B		3	Device
	media converter A			Far-End Fault			media converter B

•Both end devices are notified automatically of the link loss

•Prevents loss of valuable data transmitted unknowingly over invalid link

•Allows quick diagnosis and resolution of network problem

Transition Networks’ media converters that include the FEF feature will work with other network devices that support Far End Fault per IEEE standards.

Automatic Link Restoration (always enabled)

Transition Networks's converters will automatically re-establish the link in all network conditions:

•Without a device reset, the converters will automatically re-establish the link when connected to switches after a link loss.

•With Auto-Negotiation enabled, automatic link restoration allows using Auto-Negotiation with Link-Loss Notification.

•With Link Pass-Through enabled in both directions, automatic link restoration allows using Link-Loss Notification in both directions.

CAUTION: Associated Ethernet wiring shall be limited to inside the building.

Installing fiber cables

1.Locate a 100Base-FX fiber cable with male, two-stranded TX to RX connectors installed at both ends.

2.Connect the fiber cables to the SPOEB10xx-100 media converter as described:

•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 cables to the other device (another media converter, hub, etc.) as described:

Install the copper cable

1.Locate 100Base-TX copper cables with male, 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 media converter.

3.Connect the RJ-45 connector at the other end of the cable to the RJ-45 port on the other device (wireless access point, VoIP phone, network camera, etc.).

Connecting power

1.Connect the barrel connector, on the power adapter, to the power port on the media converter (back panel).

2.Connect the power adapter plug to AC power.

3.Verify that the converter is powered by observing the illuminated LED power indicator light on the front panel

Note: If an under or over voltage condition is detect on the main power input, the error LED will turn ON. This means that the LED will stay ON even if the voltage returns to a valid level. This condition indicates a problem with the power supply adapter; therefore, the power supply adapter should be replaced.
