Power the Media Converter
NOTE:
The external power supply provided with this product is UL listed by
the power supply’s manufacturer.
1.
Connect the barrel connector on the power adapter to the media
converter’s power port
(located on the back of the media converter).
2.
Connect the power adapter plug to AC power.
3.
Verify that the media converter is powered by observing the illuminated
LED power indicator light.
For DC power, consult the user’s guide for the Transition Networks SPS1872-
xx DC External power supply for powering the media converter.

Product Features
Link Pass-Through
The Link Pass-Through feature 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 (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.

AutoCross™
The AutoCross feature allows either straight-through (MDI) or crossover (MDI-
X) copper cables to be used when connecting to 10/100Base-TX devices.
AutoCross determines the characteristics of the connection and automatically
configures the unit to link up, regardless if the copper cable is MDI or MDI-X
configuration.
Auto-Negotiation
The Auto-Negotiation feature allows the media converter to automatically
configure itself to achieve the best possible mode of operation over a link.
The media converter broadcasts its speed (10 Mb/s or 100Mb/s) and duplex
capabilities (full or half) to the other devices and negotiates the best mode of
operation. Auto-Negotiation allows quick and easy installation because the
optimal link is established automatically. No user intervention is required to
determine the best mode of operation.
NOTE:
The SSETF10xx-205 series media converter does NOT support rate
conversion between 10Mb/s and 100Mb/s network devices.
