I suspect this question belongs in a different Stackexchange, but then again maybe not :) - Welcome to Stack Exchange.

Firstly, and this is just a guess because each manufacturer does their own thing, the wiring in the 568A punchdown block looks like it may be wrong (swapped). You should, if a new build, call the contractor and ask them to confirm the wiring order to the specific patch panel they used.

Assuming your yellow cable is good, and this cable is connected to a room with an actual device plugged in, AND the yellow cable is plugged into a LANport on the router, you should be all set.

1. Check your cable, make sure it is a good cable.
2. Check the end point, try a different room and jack. Ensure the wires trace out right.
3. Call contractor or rewire the patch panel and RJ45 jacks as needed, if needed.

Here is the link to the product install guide for the punchdown block. It looks wired right. Are the wired tight? (Use a flashlight, look close, see if the sheathing of the wire has a blade cut through on it to ensure good electrical connectivity): https://icc.com/wp-content/uploads/2017/08/MSR-0411RevJ_DataModuleCAT5eCAT6_Installation_Instructions.pdf
