Connected to the far end with
an RJ-45 straight-through
connector instead of a
cross-over cable.
If you are using a straight-through
cable, replace it with an RJ-45
cable.
The equipment at the far end of
the cable is not operational.
Verify that the far end is enabled
and is actively sending a signal
down the cable.
The cable is broken. As an experiment to isolate the
failure, use a small loopback cable
to connect the Cisco 10000 line
card to itself. If the LED lights
under this condition, continue to
investigate cable or far-end
equipment failure. Try replacing
the cable.
Defective line card. Replace the line card.
