1. Make sure that the Ethernet cable is plugged into the correct port on the
SS-300-AT-C-55-E 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 SS-300-AT-C-55-E AP/Sensor did not receive a valid IP address from the DHCP
server, ensure that a DHCP server is ON and available on the VLAN/subnet to which
the AP/Sensor is connected. If the AP/Sensor still fails to obtain a valid IP address,
reboot the device once to check whether the problem gets resolved.
3. If you are using AirTight Cloud Services, ensure that Internet connectivity is available
from the VLAN/subnet to which the AP/Sensor is connected. Check if the required
ports for AP/Sensor 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 filtering, ensure the settings allow communication between the AP/Sensor
and AirTight Cloud Service.
4. This is a rare occurrence and usually indicates a failure of the Wi-Fi radio. Try rebooting
the AP/Sensor once to check if it functions normally.
After following these guidelines, if you are still unable to resolve the problem, contact the
local AirTight SE or 24/7 AirTight Technical Support.
