    Introduction

    Cisco Aironet 3502i Access Point has NO Light

    Scenario

    Newly mounted Aironet 3502i shows no lights. The access point is working fine and is visible in the switch, WLC and WCS. The ping request is getting replies. Everything is working as expected even then the lights are not ON.

    User tried to shutdown the port in the switch and noticed it turns green (booting), once it was registered in WLC the light goes off. Currently all 4 Access Points having same issue i.e. no light but working fine.

    Great information, however I am not able to view the LED settings using the GUI on version 7.0.116, can you verify that the global LED option is present on this version of code (5508 7.0.116).

    Thanks,
