We have about 20 IAP-205 connected to a Aruba wireless instance controller. Everything has been running great. Today I added 3 IAP-205. They lights on power lit and then all other lights come on. After some time I came back an checked on status. Now only PWR (Green solid) ENETO,ENET1 (OFF), 5GHZ (AMBER solid), 2.4GHZ (AMBER solid). They are not showing on the controller. No changes have been made to controller. I added 3 one week ago without problem. I have only 20 showing on controller. Thanks for the help.
