Physical Layer
Is there an optical signal between the TN230X and the A500?

of signal on the fiber? Recall that the TN230X detects continu ity problems
with either the Transmit (bottom) or the Receive (top) fibers.
2. Is the A500 port’s CD LED off, indicating a loss of sig nal on the fiber? Note

(right-hand) fiber; the state of the Transmit (left-hand) fiber is not d etected.
