Hi,
Im using 2 Aruba Indoor 325 AP with a v6.4.4.8-4.2.4.18_78941 in my cluster environment, both are configured to act like unified AP if cluster got broken
Network topology be like Firewall >> PoE switch >> AP's for wireless access
I'm planning to upgrade the existing AP's with New Aruba Indoor 535 AP, so 12 Nos of this model AP
I'm trying to configure this new AP before deployment, since i don't bought any Power adapter for this new AP nor we do have any additional PoE switch hence i connected one new AP to the existing PoE switch,
As default new AP got IP from DHCP release from my FW
When i try to get access into the new AP, Im unable to login in to this new device with default username (admin) and password (serial no of the device) it throws me username, password incorrect error... even i have tried with cluster credentials but it didn't work... any idea why this happened ?

Also Im planning to deploy 12 qty of AP 535, can anyone suggest any PoE switch model for smooth functioning of AP ?
