Installation

CAUTION: All installation and service must be performed by qualified service
personnel. Read and follow all warning notices and instructions marked on the
product or included in the manual.
Product features
AutoCross (always enabled)
The AutoCross™ feature allows either straight-through (MDI) or crossover (MDI-
X) cables to be used when connecting to 100Base-TX devices, such as wireless
access point, VoIP phone, network camera, etc. AutoCross determines the
characteristics of the cable connection and automatically configures the unit to
link up, regardless of the cable configuration devices.
Automatic Link Restoration (always enabled)
Transition Networks's converters will automatically re-establish 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.
Auto-Negotiation (always enabled)
The Auto-Negotiation feature allows the media converter to bring up the copper
links to the highest speed and mode possible for all the attached network
devices.

Far-End Fault (always enabled)
A 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 links on both ends, alerting
both end devices of network trouble. See diagram below.
• 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.

Link Pass-Through (always enabled)
The Link Pass-Through allows the media converter to monitor both the
fiber and copper RX (receive) ports for loss of signal. In the event of a loss
of an RX signal on one media port, the media converter will automatically
disable the TX (transmit) signal of the other media port, thus, "passing
through" the link loss.
The far-end device is automatically notified of the link loss, which prevents
the loss of valuable data unknowingly transmitted over an invalid link. See
diagram below.
