I have 4 ap50 and 1 ap30. 3 ap50 online, 1 ap50 and ap30 as backup.
Configuration: 2 SSID+3 Vlans, 2 Vlans for SSIDs and 1 Vlan tagged for management access.
This configuration worked perfectly from UTM7-9.
Recently I upgrade the ASG220 to 9.315-2. So I thought the two backup APs need to be upgraded too, but the backup AP didn't work like before. Before, I just need to plugged the AP to trunk port on switch and the AP will be online automatically.
Here is what I did before:
1 Delete record from UTM wireless protection
2 Flash the APs.
3 Plug the AP50 to untagged switch port.
4 ASG finds the AP50, then add in.
5 Then assign the two wireless networks to the AP, add taged vlan to the ap. Save the configuration.
6 Unplug from the untagged switch port, plug to the trunk.
Nothing happened. 2.4ghz and 5ghz lights never on. Power light flashing.
1 Same configuration, Same ports (Tagged and untagged), same procedure, AP30 works fine.
2 One of the online (Old) AP50 works no problem with the tagged port.
3 All APs same configuration
4 Two new APs didn't work. All the AP50 are version 1 hardware, but got the two with problems after those 3 online APs.
Called Sophos, but when I was on the phone with support, I used external AC adapter instead of POE injector. redo the procedure 1-4 and worked!! So I closed the ticket as I thought the problem is the firmware for POE.
But today, when I disconnected the AP50, I CAN'T get them back to online again. Tried many times, no luck.
Any clues?
