Changing a Cassette: How do I identify the patched cable?

Step 1:

Check the ID Label and your documentation.

Step 2:

If you are not using any documentation, hold the cable at the PATCHBOX Cassette you want to change and give it a careful wiggle. There should not be any tension on the cable (read more here), so it should wiggle a little. Follow the cable movement with your eye until you find the port it is patched to.
