FAULT ISOLATION and CORRECTION
If the media converter fails, isolate and correct the fault by determining the
answers to the following questions and then taking the indicated action:
1. Is the P(o)W(e)RLED on the media converter illuminated?
NO
• Is the power cord properly installed in the media converter and in
the grounded AC outlet?
• Does the grounded AC outlet provide power?
• Contact Technical Support: (800) 260-1312/(800) LAN-WANS.
YES
• Proceed to step 2.
2. Does one of the green 100BASE-TX Status LEDs blink once* and
go off?
YES
• Check twisted pair cables for proper connection.
• Contact Technical Support: (800) 260-1312/(800) LAN-WANS.
NO
• Proceed to step 3.
3. Does one of the green 100BASE-FX Status LEDs blink once and
go off?
YES
• Check fiber cables for proper connection.
• Verify that TX and RX cables on media converter are connected to
RX and TX ports, respectively, on other device.
• Contact Technical Support: (800) 260-1312/(800) LAN-WANS.
NO
• Proceed to step 4.
4. Does one of the green 100BASE-FX Status LEDs blink twice and
go off?
YES
• Determine cause of Far End Fault and then repair or replace faulty
cable or equipment in copper link.
• Contact Technical Support: (800) 260-1312/(800) LAN-WANS.
NO
• Proceed to step 5.
*If one of the 100BASE-TX Status LEDs blinks twice, the 100BASE-TX
link is Auto-Negotiating. If the media converter port is connected to a
100BASE-TX device, no action is necessary. If the media converter port
is connected to a 10BASE-T device, the multi-port media converter will
not operate properly.
Install Cable
COPPER
NOTE: KEEP TWISTED PAIR RUNS AS SHORT AS POSSIBLE.
NOTE: AutoCross™ allows the use of either straight-through or crossover
configuration cables.
1. Locate or build 100BASE-TX compliant cables with male RJ-45
plug connectors at both ends.
2. Connect male RJ-45 plug connector at one end of cable to media
converter port RJ-45 jack connector.
3. Connect male RJ-45 plug connector at other end of cable to
100BASE-TX device RJ-45 jack connector.
FIBER
1. Locate or build 100BASE-FX compliant fiber cable with male two-
stranded TX to RX connectors at both ends.
2. Connect male TX and RX cable connectors at one end of cable to
TX and RX female connectors, respectively, on media converter
port.
3. Connect male TX and RX cable connectors at other end of cable to
RX and TX connectors, respectively, on 802.3 compliant fiber
device.
Connect to Power
1. At multi-port media converter back, locate male power receptacle.
2. Plug female media converter end of power cord into multi-port
media converter power receptacle.
3. Plug male outlet end of power cord into correct voltage, properly
grounded, AC rack or wall power source.
4. Verify that multi-port media converter is powered by observing
illuminated power and status LED(s).
