OPERATION

Using Status LEDs
Use the status LEDs to monitor media converter operation in the network.
100 Steady LED indicates 100 Mb/s
operation.
One (1) continuous, slowly flashing
speed selection in
blink indicates
progress.
One (1) continuous, quickly flashing
blink indicates 100 Mb/s operation
Po(W)e(R) Steady LED indicates connection to
external AC power.
STAT(us) (10/100TX) Steady LED indicates
normal operation.
One (1) continuous, flashing blink
indicates Link Down.
Five (5) continuous, flashing blinks
when the selected speed is 10 Mb/s
indicates that the receive pair has the
wrong polarity; five (5) continuous,
flashing blinks when the selected
speed is 100 Mb/s should be ignored.
ACT(ivity) (10/100TX) Flashing LED indicates
10/100BASE-TX activity.
STAT(us) (10/100SX) Steady LED indicates normal operation.
One (1) continuous, flashing blink indicates
ACT(ivity) (10/100SX) Flashing LED indicates 10/

Using AutoCross
The AutoCross™ feature allows either straight-through (MDI) or crossover
(MDI-X) cables to be used when connecting to 10BASE-T or to 100BASE-TX
devices, such as hubs, transceivers, or network interface cards (NICs).
AutoCross™ determines the characteristics of the cable connection and
automatically configures the unit to link up, regardless of the cable
configuration.
*Requires no operator intervention.

Using Autonegotiation*
The C/E-TX-SX-02 series media converter Autonegotiation feature allows the
media converter to be used with 10BASE-T, 100BASE-TX, 10BASE-FL and
100BASE-SX ports.
The media converter will bring up the link in the highest speed and mode
possible between the station and the device.
*Requires no operator intervention.
Using LinkAlert™
The C/E-TX-SX-02 series media converter LinkAlert™ feature allows the
media converter to pass 10/100BASE-TX-side link faults over the link to the
10/100BASE-SX side and to pass 10/100BASE-SX-side link faults over the link
to the 10/100BASE-TX side.
If the C/E-TX-SX-02 media converter does not detect a good link on the
10/100BASE-TX side, the C/E-TX-SX-02 disables all transmission (including
active-idle) on the 10/100BASE-SX side.
