The switch weighs 3.9 kg (8.6 lb) without mounting brackets and 4 kg (8.8 lb) with them. Its enclosure is made of SGCC steel. It features an Ethernet In-Band management interface, 48 GbE RJ45 ports, and 4 1G SFP Ethernet ports. With a total non - blocking throughput of 52 Gbps, a switching capacity of 104 Gbps, and a forwarding rate of 77.376 Mpps, it offers high - performance networking. It uses a universal input power method (100 - 240V AC, 50/60 Hz) with an internal AC/DC 60W power supply. The max power consumption is 40W. It has ESD/EMP protection (Air: ± 16kV, contact: ± 12kV), a 1.3 - inch touchscreen LCM display, and a factory reset button. It operates in a temperature range of - 15 to 40°C (5 to 104°F) and humidity range of 10 to 90% non - condensing. It is certified with CE, FCC, and IC. The LEDs show system status, Ethernet speed/link/activity, and SFP link/activity. It requires UniFi Network version 7.2.94 and later.

Using this Unify Switch 48 is quite easy. First, make sure your UniFi Network is at version 7.2.94 or later. Connect the switch to a power source within the 100 - 240V AC range. You can then start connecting your devices to the GbE RJ45 ports or the 1G SFP Ethernet ports. The touchscreen LCM display helps you manage the switch easily. If you ever need to reset the switch to its factory settings, just press the factory reset button. When it comes to maintenance, keep the switch in a place where the temperature is between - 15 and 40°C and the humidity is 10 to 90% non - condensing. Avoid exposing it to extreme electrostatic or electromagnetic fields as it has limited ESD/EMP protection. Also, check the LEDs regularly to monitor the system status, Ethernet connections, and SFP links. This way, you can ensure the long - term performance of your switch.
