Regenerate PoE Licenses for legacy Aruba 620


I have an old Aruba 620 unit that came into my team's network lab recently. Unfortunately, I erased the licenses off the controller during reconfiguration, and now PoE no longer runs off the box. Additionally, we were not given the power adaptors and our setup requires PoE to run the APs. 

As the 620 has been EOS'd and the old licensing webpage is defunct (, is there anyway for me to regenerate the licenses for this unit?


Thanks any and all assistance.

Type "dir" on the commandline to see if there is a flashbackup.tar.gz file.  If there is, maybe it has a license.  Do a "restore flash" and reboot to see if the licenses reappear.

Backup file was still intact, and reboot worked like a charm. Thank you so much!
