Safety Guidelines

Warning - Risk of electric shock or fire.

• Connect the Product power adaptor or cord to the right supply voltage of Local Philippine Government.
• The socket-outlet shall be easily accessible. Pay attention to the power load of the electrical outlet and possible extension cord.
• An overburdened power outlet or damaged cords and plugs may cause electric shock or fire. Check the power cords regularly. If you find any damage, replace the cord immediately.
• Do not connect the plug into an extension cord, receptacle, or other outlet unless the plug can be fully inserted with no part of the blades exposed. Leave adequate space for heat dissipation to avoid any damage caused by overheating the Product.
• Do not cover the Product or its ventilation holes. Blocking the ventilation holes may cause fire. Use the power adapter provided with your Product and do not fasten the power cable to building surfaces. Ensure the cable can move freely.
• Do not place heavy objects on the cable.
• Do not use the Product outside, and make sure all the connections are indoors.
• Do not install, use, or service this Product during a thunderstorm. There is a remote risk of electric shock from lightning.

Installation Precautions

• The device should only be installed by qualified personnel according to local laws and regulations.
• Check the voltage rating before connecting the power. It is recommended not to share the same power socket with other high power-rated devices (e.g., hairdryer, refrigerator, iron).
• Do not place the device near flammable or conductive materials, high temperature (direct sunlight), moisture, or other appliances that produce heat.
• Always ensure the device is properly ventilated; do not place any objects on the device to avoid over-heating.
• Ensure the device is installed on an even surface.
• The power socket and power cable shall be inspected regularly and must be replaced if damaged to avoid risk of electric shock or fire.

Operation Cautions

• Do not look directly at the optical port without protection.
• Do not insert any sharp object into the openings of a Product.
• Do not put the Product near a heat source. Avoid placing the Product in direct sunlight.
• Do not put the Product in damp or wet locations (e.g., near a bathtub, washbowl, kitchen sink, laundry tub, wet basement, or swimming pool).

Accessing the Web GUI

You can customize your ONT's configuration using the web graphical user interface. Altering the default configuration is not recommended if you are unfamiliar with the settings.

1. Set the LAN setting to obtain an IP Address automatically.
2. Open a web browser and enter the default gateway IP address http://192.168.254.254 in the address bar. The default gateway IP address is printed on the product label on the back panel of the ONT. You can connect to this IP address using your web browser after connecting your PC to one of the Ethernet ports of the ONT. Your PC's static IP address must be in the same subnet as the ONT. The login window will appear.
3. Enter your username and password in the login window. The default username and password are printed on the product label on the back panel of the ONT.
4. Click Login.

The web GUI displays device information and provides options for WAN status, Network settings, Wi-Fi settings, and other configuration changes. Altering network settings is not recommended when internet connections are already established and working.

After logging in, you can check the ONT's internet and Wi-Fi connection status on the "dashboard and status" page. You can configure LAN/Wi-Fi attributes by clicking the configuration item on the left.
