ATM Physical Layer Statistics 9-13

If you suspect that the fiber optic cable is not

working, replace the cable with a cable known to be

working, and check the Link Status LED.

Check that the cable has not been accidently plugged

into an FDDI connector at one end of the connection.

Check that the ATM Module and ATM Switch are

using compatible transmit clocking options.

Check that the Line Rate settings on the two devices

are compatible.

If there is still a problem, contact your repair center

for advice. For more details, refer to Appendix E.
