Using the Fiber Optic Transceiver
The transceiver can be used to attach a 10BASE-T hub, through
another transceiver, to a terminal device or to another 10BASE-T hub.
1. Is ANY LED on the E-FL/RED-MC01 illuminated?
NO
•
Verify that the E-FL/RED-MC01 is installed properly in the AUI port and that the device
to which the E-FL/RED-MC01 is attached is powered ON.
•
Contact Technical Support at (800) 260-1312 or at (800) LAN-WANS.
YES
•
Proceed to step 2.
2. Is the Link LED illuminated?
NO
•
Check fiber cables for proper connection.
•
Verify that TX and RX cables on one media converter are connected to RX and TX ports,
respectively, on the other media converter.
•
Contact Technical Support at (800) 260-1312 or at (800) LAN-WANS.
YES
•
Contact Technical Support at (800) 260-1312 or at (800) LAN-WANS.
2. Is the Fault LED illuminated?
YES
•
Contact Technical Support at (800) 260-1312 or at (800) LAN-WANS.
CAUTION: Wear a grounding device and observe
electrostatic discharge precautions when setting
SQE switch. Failure to observe this caution could
result in media converter failure.
The SQE jumper is located inside the metal case of
the Redundant Fiber Optic Transceiver.
With a medium
Phillips
screwdriver,
remove the screws
from the sides and
back of the
transceiver.
Remove the cover and locate the SQE jumper, as
shown in the illustration below.
Place the SQE
jumper in the
proper (ON or OFF)
location.
Troubleshooting the Media Converter
Installation Notes
If the E-FR/RED-MC01 fails, determine the answers to the following questions:
NOTE: The transceiver is shipped with the internal SQE switch set to
OFF.?????? See below for direction for changing the switch setting.
SQE ON: Set the (internal) SQE switch to enabled (ON) when the
transceiver is connected to a terminal device.
SQE OFF: Set the (internal) SQE switch to disabled (OFF) when the
transceiver is connected to a hub.
