Ubiquiti UniFi USW-Mission-Critical Managed PoE Switch

The Ubiquiti UniFi Switch Mission Critical (Part Number: USW-Mission-Critical) is a unique Layer 2 managed PoE switch specifically engineered to ensure uninterrupted network availability during power outages and emergencies. It integrates advanced switching capabilities with a built-in uninterruptible power supply (UPS), making it an ideal solution for mission-critical applications such as surveillance, building control, and essential network services.

The switch includes 8× 1 Gigabit RJ45 ports, divided into 4× PoE+ ports (802.3at) and 4× PoE++ ports (802.3bt), delivering up to 120W of total PoE power. In addition to its standard RJ45 ports, the unit features a 1× 1 GbE uplink port for connectivity to core network infrastructure. Designed to be deployed in locations where downtime is not an option, this switch ensures that power and data delivery remain active for essential systems even when the main power source fails.

Its standout feature is the integrated Li-ion battery system, which provides backup power to connected devices during outages. When used in conjunction with the UniFi SmartPower Redundant Power System (USP RPS), it can seamlessly switch to RPS power or battery mode without disruption. The switch’s smart power logic prioritizes which devices receive power during backup operation, ensuring that the most critical equipment remains active.

The USW-Mission-Critical is managed through the UniFi Network Controller, where users can define PoE power priority levels, view real-time battery health, monitor power draw, and configure port settings. The centralized interface also allows for firmware updates, VLAN configuration, and traffic monitoring, just like other UniFi switches. With remote monitoring capabilities, IT teams can receive alerts and status updates about power events and battery conditions from anywhere.

Compact and designed for edge deployment, the fanless unit offers silent operation and is suitable for placement in cabinets, wall enclosures, or IT closets. It is especially well-suited for locations such as retail floors, schools, medical offices, and industrial facilities where network continuity is crucial for safety, security, or operational efficiency.

In conclusion, the Ubiquiti USW-Mission-Critical combines intelligent Layer 2 switching, advanced PoE delivery, and built-in battery backup in a compact, UniFi-integrated form factor. It is purpose-built for organizations that cannot afford network interruptions and need a reliable solution for maintaining essential connectivity during unexpected power loss.
