Frequently Asked Questions
What is a 2.5 GbE switch and why do I need one?
A 2.5 GbE switch provides multi-gigabit connectivity between devices, delivering 2.5× the bandwidth of standard 1 GbE switches. It's ideal for high-bandwidth applications like 4K video streaming, large file transfers, and modern NAS deployments without the cost of full 10 GbE infrastructure.
Can the Switch Flex 2.5G be powered by PoE+?
Yes. The Switch Flex 2.5G supports both USB-C power and PoE+ (802.3at) input, allowing you to power it directly from a PoE+ injector or compatible upstream switch. This eliminates the need for separate power supplies in wall-mounted or remote deployments.
Does this switch work with UniFi network management?
Absolutely. The Switch Flex 2.5G integrates seamlessly with the UniFi ecosystem, enabling centralized management, real-time monitoring, VLAN configuration, and traffic analytics through the UniFi Controller dashboard.
What is the 10 GbE uplink port used for?
The dual-mode 10 GbE RJ45/SFP+ combination uplink connects the switch to your network backbone or core infrastructure, providing high-speed aggregation for multiple 2.5 GbE clients. Use RJ45 for copper connections or SFP+ for fiber-optic links.
