Hello Ravi,
From what I can see, this AP is not under the 90 day software warranty period or under any support agreement.
My recommendations:
1 - Acquire a support agreement:
https://gtacknowledge.extremenetworks.com/articles/Q_A/where-can-I-purchase-or-renew-a-support-contract-for-my-wireless-controller-and-APs
2 - Upgrade the lot to version 5.9.3.3:
https://gtacknowledge.extremenetworks.com/articles/How_To/How-to-upgrade-adopted-APs-from-the-virtual-controller
Currently, the VC will see the newly added AP but will not push the config to it. If you run the command '#show adoption status',
and look under the CFG-STAT column, you should see 'version mismatch' for this particular AP. All APs should be on the same firmware version.
I hope this helps,
Thank you,
Chris
