Installation -- Continued
Power the Media Converter
NOTE: The external power supply provided with this product is UL listed by
the power supply’s manufacturer.
AC
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.
DC
Consult the user’s guide for the Transition Networks SPS1872-xx DC external
power supply for powering the media converter.
Operation
Status LEDs
Use the status LEDs next to the fiber ports to monitor the media converter and
the fiber network connections.
F(ull) D(uplex)
On = Full-duplex connection.
Off = Half-duplex connection.
L(ink) ACT(ivity)
On = Fiber link connection.
Flashing = Fiber network activity.
P(o)W(e)R
On = Connection to external AC or DC power.

The “FD” and “LACT” LEDs near the top of the media
converter refer to Fiber Port 2 (F2).
The “FD” and “LACT” LEDs near the bottom of the media
converter refer to Fiber Port 1 (F1).

Use the bi-color twisted-pair status LEDs to monitor the twisted-pair copper
network connections.
Duplex/Link LED
Amber = A link in half-duplex mode has been
established for the twisted-pair copper link.
Flashing Amber = Activity on the half-duplex
copper link.
Green = A link in full-duplex mode has been
established for the twisted-pair copper link.
Flashing Green = Activity on the full-duplex
copper link.
Speed LED
Amber = 10Mb/s operation.
Green = 100Mb/s operation.
Product Features
Full-Duplex Network
In a full-duplex network, maximum cable lengths are determined by the type
of cables that are used. See pages 1 and 2 for the cable specifications for the
different SBFTF10xx-14x models.
The 512-Bit Rule does not apply in a full-duplex network.
Half-Duplex Network (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:
