The Ubiquiti UniFi Mission Critical (USW-Mission-Critical) is a high-performance Layer 2 managed switch specifically engineered to provide uninterruptible power and connectivity for essential network infrastructure. Designed for enterprise-grade deployments in environments such as hospitals, hotels, and emergency services, this rack-mountable unit ensures that your most vital devices remain operational even during a primary power failure.

Uninterrupted Power Delivery
What sets the Mission Critical switch apart is its sophisticated internal power system. It features an integrated 368Wh lithium-ion backup battery, designed to provide immediate failover support for connected PoE devices. For extended redundancy, the unit includes an external 48V DC battery input, allowing for further customisation of your backup capacity. Additionally, two 230V AC power outlets are included to support non-PoE critical hardware, such as gateways or modems, providing a comprehensive power solution for an entire network rack.
Advanced Networking and PoE Support
This 9-port Gigabit switch is built to handle high-demand devices with ease. The port configuration includes:
4 x 802.3bt PoE++ ports: Delivering up to 60W per port, ideal for powering UniFi Access hubs and high-performance building security systems.
4 x 802.3af/at PoE+ ports: Perfect for powering wireless access points, VoIP phones, and surveillance cameras.
1 x GbE RJ45 uplink port: Providing a high-speed connection to your primary gateway.
Intelligent Management and Monitoring
Equipped with a 1.3" colour touchscreen LCM display, the Mission Critical switch offers instant at-a-glance monitoring of system status and power usage. For professional administrators, the switch supports a full suite of Layer 2 features, including VLAN tagging, port isolation, and IGMP snooping. Integration with the UniFi Network application enables centralised management, allowing you to monitor and optimise your network infrastructure from a single, intuitive interface. The unit is also compatible with Augmented Reality (AR) technology, simplifying port identification and maintenance in complex rack environments.
