Set RX and TX Clock Polarity Jumpers
J6
–
RX Clock Polarity
Selects the polarity of the receive clock.
When in A position, receive data (RxD) is sampled on rising edge
of Receive clock (RxC). When in B position, receive data (RxD) is
sampled on falling edge of Receive clock (RxC).
J7
-
TX Clock Polarity
Selects the polarity of the transmit clock.
When in A position, Transmit Data (TxD) is sampled on rising edge
of Transmit clock (TxC). When in B position, transmit data (TxD) is
sampled on falling edge of Transmit Clock (TxC).

FAULT ISOLATION & CORRECTION
If the media converter fails, isolate and correct the failure by
determining the answers to the following questions and then taking
the indicated action:
1.
Is the P(o)W(e)R LED on the media converter illuminated?
NO
•
Is the power adapter cord inserted properly into the
media converter?
•
Is the power adapter cord installed properly at the
external power source?
•
Does the external power source provide power?
•
If using SNMP management, has media converter been
powered OFF at software interface?
•
Contact Technical Support: (800) 260-1312.
YES
•
Proceed to step 2.
2.
Is the C(opper) L(ink) LED illuminated?

•
Is device attached to media converter by copper cable
working properly.
•
Is data present on the cable?
•
Contact Technical Support: (800) 260-1312.
YES
•
Proceed to step 3.
3.
Is the F(iber) L(ink) LED illuminated?
NO
•
Are fiber cables connected properly.
•
Are TX and RX cables on media converter connected to
RX and TX ports, respectively, on other media
converter.
•
Is data present on the cable?
•
Are both media converters in the same mode
(synchronous or asynchronous)?
•
Contact Technical Support: (800) 260-1312.
