We upgraded some Cisco Access Points with newer Aruba Access Points (all PoE) and we noticed that after swapping the AP and reconnecting the ethernet cables, there would be no LED status lights at all on the system or the Radio LED indicator (AP Model 315 Aruba). We had to switch to different modes to get back the system and radio lights. Not sure why that would be the case. The switch port is still working as I tested with my laptop so why did we have to switch to different switch ports for the new Access Points to work?
We even power cycled the switch (due to different reason and I tried shut/no shut (in case the switch port went to err-disabled).
Does any know know why?
