Hi,
if the APs are at factory default they'll try to reach activate at least at every boot. But you can not build a policy in activate to "send" them to central. You have to add them into your central account. Central will then create a activate policy for you. If Aruba got the right information from your distribuor and activate and central accounts somehow match, then these APs are already assigned to your activate and central accounts and you just can select them in central.
Looks like this is not your case. So in central you can add them by MAC-address or serial number.
At next reboot, they should be visible in central. (takes some time).
So I suggest:
- add them to central
- disable all but one (easier to see, whats going on) e.g by disabling PoE/Switchport/disconnecting them
- factory reset that one again or just reboot
- check in central
- restart the rest
- check in central
- they'll form a cluster again with the one started first as VC. Even if the rest is not defaulted, they should join the cluster, unless you disabled autojoin or disabled swarmode in bootenvironment or similar.
IP address should be provided by your infrastructure with DHCP (plus gateway, dns, ntp-timeserver, ...). Otherwise they'll not be able to reach central. Don't forget firewall rules, if one is in place.
