The Ubiquiti UniFi Mission Critical Switch is a Layer 2 PoE switch featuring an integrated 368Wh lithium-ion battery backup system. It is designed to maintain network operation for your most important devices during a power failure. The switch provides a total PoE budget of 120W, distributed across four Gigabit PoE+ and four Gigabit PoE++ ports, making it suitable for powering access points, IP cameras, and VoIP phones. In addition to its networking ports, it includes two 230V AC outputs, allowing it to function as a complete uninterruptible power supply (UPS) for other critical equipment. This ensures your essential infrastructure remains online when mains power is unavailable.
