After the O-90 is powered ON and connected to Ethernet, if the status
of Power (PWR) LED is not Solid Green, it indicates that the AP is not able to function

1. Make sure that the Ethernet cable is correctly plugged into the LAN1 (POE) port on
the O-90 and the other end of the cable is plugged into an Ethernet jack or a port on
a switch that is turned ON.
2. If the O-90 did not receive a valid IP address from the DHCP server, make sure that a
DHCP server is ON and available on the VLAN/subnet to which the AP is connected. If
the AP still fails to get a valid IP address, you can reboot it once to see if that resolves
the problem.
3. If you are using AirTight Cloud Services, make sure that Internet connectivity is
available from the VLAN/subnet to which the AP is connected. Check if the required
ports for AP and Server communication – UDP 3851 and default HTTP (TCP port 80)
– are open on the Firewall. If you are using a Proxy, Web accelerator or URL content
ltering, make sure the settings allow communication between the AP and AirTight
Cloud Services.
After following these guidelines, if you are still unable to resolve the problem, contact the
local AirTight Sales Engineer or 24/7 AirTight Technical Support.
