UniFi’s Advanced High Availability Solutions
UniFi’s Enterprise lineup prioritizes redundancy to ensure maximum network uptime and reliability by eliminating single points of failure.
UniFi enables High Availability across your deployment by building redundancy into every part of the network—from Gateways to Switches to Access Points—so that if one component fails, another instantly takes over.
Enterprise Fortress Gateway and Shadow Mode
Enterprise Fortress Gateways feature an active-passive failover mechanism known as Shadow Mode. This technology leverages Virtual Router Redundancy Protocol (VRRP) to monitor the health of the primary gateway, and seamlessly let the passive spare take over in the event of hardware failure. Thanks to firewall connection state tracking, the failover process will be practically invisible to your end users, ensuring that their productivity remains unaffected.
Combined with multi-WAN load balancing and hot-swappable power supplies on the Enterprise Fortress Gateway, you can be confident that your network’s edge is suited for any failure mode.

Enterprise Campus Aggregation and MC-LAG
The Enterprise Campus Aggregation is a high-capacity 100G switch that extends redundancy to the core of your network. It features Multi-Chassis Link Aggregation (MC-LAG), which allows combining two physical switches into a single logical unit. This enables link aggregation of ports across both switches to effectively load balance traffic, and more importantly provide nearly instant failover in the event of a link failure, port failure, or even an entire switch failure.
Similar to the EFG, it also features hot-swappable power supplies and hot-swappable fans to further enhance redundancy and maintain operational continuity no matter what happens.

Enterprise Campus 24/48 Redundancy
The Enterprise Campus 24/48 switches provide 25G uplinks, hot-swappable power supplies and fans, and PoE+++ (90W) to support high-performance devices. Their redundant architecture ensures seamless failover in case of port, cable, or switch failure. When paired with MC-LAG at the aggregation layer, they create a highly resilient access network.
Additional resilience will come with Switch Stacking, which will be available on upcoming ECS models.
E7 Series Access Points
UniFi’s E7 Series Access Points (E7, E7 Campus & E7 Audience) are built for WiFi 7 performance in high-density environments. They feature a 10GbE primary uplink and a 1GbE secondary port for redundant power and data when connected to separate switches. With Multi-Link Operation (MLO), they optimize traffic across all bands for better performance and lower latency. Powered via PoE++, they integrate seamlessly with the Enterprise Campus 24/48 switches for a fully redundant wireless network.
LTE Backup
UniFi’s LTE Backup Pro ensures uninterrupted connectivity by automatically switching to a cellular network when other internet connections go down. Designed for flexibility, LTE Backup Pro can be physically connected anywhere in your network, so it can be placed where LTE signal strength is optimal. To optimize performance and control costs, administrators can selectively enable LTE failover for critical networks, such as point-of-sale systems, while disabling it for bandwidth-heavy ones like guest WiFi. Data limits and alerts can also be configured to prevent unexpected overages. Learn more here.
