- Quick Start Guide
Using the Ubiquiti UniFi UFiber OLT 4 is quite straightforward. First, find a suitable place to install it. Thanks to its rack - mountable design, you can easily place it in a rack. Connect the power cord to a power source within the supported voltage range of 100 - 240V AC or 16 - 25V DC. Then, connect your devices to the appropriate ports. You have four GPON OLT SFP ports for connecting ONUs and a 10 Gbps SFP+ port for other networking needs.
When it comes to configuration, use the Ubiquiti UniFi Network application. It allows you to manage and set up the device centrally. You can also use the Ethernet Out - of - Band Management or the RJ45 Serial Console port for management if needed.
Here are some important things to keep in mind. Make sure the ambient temperature is between - 10°C and 45°C and the humidity is between 10% and 90% non - condensing. This will help the device work properly. Don't touch the optical ports with your fingers as it can damage them.
For maintenance, regularly check the LEDs on the device. They can tell you if the device is powered on, if there are any link activities, etc. If you need to reset the device to its factory settings, press the factory reset button. Also, keep the device clean and free from dust. If you're not using the device for a long time, store it in a dry and cool place.
