OPERATION
After installation, the transceiver should function without operator intervention.
Status LEDs
Use the status LEDs to monitor transceiver operation in the network.
STATUS
ON=OK
Steady green
LED indicates
normal
operation.
Link Down:
One (1)
continuous,
flashing blink indicates no data packet or link
integrity pulse being received over twisted-pair.
Local Jabber: Two (2) continuous, flashing blinks
indicate AUI packets are too long.
Polarity Reversed: Five (5) continuous, flashing blinks
indicate receive pair has the wrong polarity. The
transceiver automatically corrects this condition if
switch 3 is UP. This warning will continue until the
wiring is corrected.
Dark LED indicates NO connection to external
power.
C0L(lision):
Illuminated amber LED indicates signal collisions on the
Ethernet cable.
TX
Flashing or illuminated amber LED indicates packet
transmission (AUI to twisted-pair).
RX
Flashing or illuminated amber LED indicates packet
reception (twisted-pair to AUI).
FAULT ISOLATION and CORRECTION
If the transceiver fails, determine the answers to the following questions:
1.
Is the STATUS LED on the transceiver illuminated?
NO
•
Verify that the transceiver is installed properly in the AUI port and
that the DTE device is powered ON?
•
Contact Technical Support at (800) 260-1312/(800) 526-9267.
YES
•
Proceed to step 2.
2.
Is the RX LED illuminated?
NO
•
Check twisted pair cables for proper connection.
•
Contact Technical Support at (800) 260-1312/(800) 526-9267.
YES
•
Proceed to step 3.
3.
Is the TX LED illuminated?
NO
•
Check AUI cables for proper connection.
•
Restart the workstation to restart the initialization process.
•
Contact Technical Support at (800) 260-1312/(800) 526-9267.
YES
•
