Troubleshooting
This is normal prior to configuration. Neither the Active nor Standby LEDs on the
card is on.
Verify that the Run/Fail LED is green. If so, the card is receiving power and POST
test results are positive. If it is off, the card is not receiving power.
Check the state of the Active LED. If it is green, the card is in standby mode. If needed,
refer to
Manually Initiating a Line Card or SPIO Switchover, on page 23
information on configuring the card to serve as a redundant component.
Troubleshooting
None needed.
NOTE: This LED will not indicate the presence of a network link until the interface
parameters are set during the software configuration process.
Verify that the Run/Fail LED is green. If so, the card is receiving power. If it is off,
the card is not receiving power.
Verify that the interface is cabled properly.
Verify that the device where the interface is connected to is cabled and powered
properly.
Check the cable for continuity.
