The following is a collection of important advice and things to be aware of.

Never look directly into a fibre connector or the end of a fibre cable. It can carry invisible laser light that can damage your eyes.
Never open your fibre termination box.
Before any drilling, point out hidden water pipes and electrical cables to the installation team so they aren’t struck by accident.
Keep your router and fibre box away from water and damp.
Make sure an adult is present whenever an installation or repair team is working in your home.

Don’t reset your router to factory defaults unless you’re sure it’s needed – you’ll lose your custom settings (WiFi name, password, port forwards, etc.).
Don’t paint over, cover, or stack things on the fibre box – it needs ventilation and clear access for repairs. Make sure you can easily reach it to reboot it or take a photo of the status lights.
Don’t remove the fibre box (ONT/CPE) – it remains the property of the FNO.
Don’t put your router into “Bridge” mode.
Don’t bend or coil your fibre patch cable too tightly – fibre is glass, and a sharp bend can cause major signal loss.
Match the power supply to the device. Check the voltage and current (amps) the router, ONT or CPE needs, and only use a PSU with the correct voltage and connector. A higher-voltage PSU can permanently damage the device.
Don’t hide your WiFi router in an enclosed space (cupboard, drawer, box) – routers generate heat and need ventilation to work reliably.
Loadshedding and power spikes can damage your fibre box and router – ideally power these devices with a DC-UPS or use a surge-protected multi-plug.
Make sure you have a laptop or PC with a Gigabit Ethernet port, so you can do a cabled speed test.
