AIR-CAP3702I, showing red indication

[BALAMURUGAN SINGARAM]

We have "AIR-CAP3702I-E-K9" some access point giving red indicator led. When the same AP is connected to switch directly it gives green indication.

Customer update us cabling is tested and passed, but the AP connected to the wall shows red indication, please suggest what could be the problem.
