Step 1
replace it with a known-good one.
Caution Removing a card that currently carries traffic on one or more ports can cause a traffic hit. To avoid this,
perform an external switch if a switch has not already occurred. Refer to the procedures in the
"1.10.1 Protection Switching, Lock Initiation, and Clearing" section on page
information, refer to the "Maintain the Node" chapter in the Cisco ONS 15310-CL and
Cisco ONS 15310-MA Procedure Guide.
Resend test traffic on the loopback circuit with a known-good card.
Step 2
If the test set indicates a good circuit, the problem was probably the defective card. Return the defective
