Basic Station Setting | ● Option 1: CUPS access is DISABLED and only LNS configuration is allowed. Configuration and FOTA happen via AWS IoT and gateway has just the LNS configuration ● Option 2: CUPS access is ALLOWED and LNS configuration is known via CUPS. But it requires a public key and LNS configuration update in CUPS to point to the desired LNS. ○ LNS URI + Port Number ○ Public Key for the gateway which has been registered with CUPS ○ Customers will then need to add MAC, Private key, and claim code onto their CUPS |

User Manual
Connect Femto Lite
You can connect to the gateway via WiFi interface which the SSID and password are printed on the back label by default.
The rule of gateway SSID is Femto_Lite where the last digits are the last 6 digits of the MAC address
The PC will fetch the IP address of range 192.168.4.x except 192.168.4.1 assigned by the AP.
Femto Lite Setting
Open the web browser(ex: Chrome) after connecting to the gateway via IP address “192.168.4.1” Now you can configure the gateway through the WEB UI.
STEP 1: SET WAN: The gateway support either “Ethernet” or “Wi-Fi” connection as the internet backhaul.
Ethernet Setting
ETHERNET STATUS – The information of IP address/Subnet Mask/Gateway/DNS.
ETHERNET SETTING – Configure the IP address of WAN.[Static IP/DHCP client] Static IP – Setup the IP address/Subnet Mask/Default Gateway/DNS of the static IP.
DHCP – The IP address/Subnet Mask/Default Gateway/DNS will be assigned by the DHCP server.
STEP Wi-Fi
The gateway WiFi interface is the Access Point by default which SSID is printed on the back label. The administrator can only access the WEB UI through the Access Point mode to configure the gateway. The gateway will be the WiFi client and won’t access the WEB UI after enabling the WiFi interface as the internet backhaul connection.
MANUAL CONNECT – Specify the remote AP SSID and enter the password if necessary.
The gateway will scan the neighbor’s access point automatically. Just click the SSID for the WiFi connection.
Enter a WiFi password if it is necessary for the connection.
