Description
The UniFi Flex 2.5G PoE is a Layer 2 managed switch featuring eight 2.5 GbE PoE++ ports and one 10 GbE uplink port, centrally managed via UniFi Network.
Key Features
60 Gbps switching capacity with 30 Gbps non-blocking throughput and 45 Mpps forwarding rate
Eight PoE++ ports delivering up to 64W per port for direct device power
10G SFP+ uplink alongside the 10 GbE RJ45 port for high-speed fiber connections
Compact form factor with desktop, wall, DIN rail, and magnetic mounting options
Full Layer 2 features including STP/RSTP, port isolation, storm control, and loop protection
NDAA compliance
Performance and Connectivity
The switch includes eight 2.5 GbE RJ45 PoE++ ports supporting 2.5G, 1G, 100M, and 10M speeds, one 10 GbE RJ45 PoE+++ port compatible with 10G/5G/2.5G/1G/100M, and one 10G SFP+ port for 10G or 1G fiber. Switching capacity reaches 60 Gbps with a total non-blocking throughput of 30 Gbps and a forwarding rate of 45 Mpps. The MAC address table supports up to 4,000 entries and 256 VLANs, with jumbo frame support.
PoE Power
The eight 2.5 GbE ports deliver PoE++ with a maximum power of 64W per port, 32W in PoE+ mode, and 15.4W in PoE mode. Total PoE availability varies by input method: 76W with PoE+++ input, 46W with PoE++ input, 16W with PoE+ input, and 196W with a 210W AC adapter. The switch accepts a voltage range of 50–57V DC/PoE and can be powered via PoE+++ or an optional AC/DC adapter. Maximum device power consumption is 14W without PoE output on PoE input, 17W without PoE output on AC adapter input, and 210W including PoE output.
Management and Layer 2 Features
Management is handled over Ethernet using the UniFi Network application, requiring version 9.0.114 or later. The switch supports STP and RSTP, egress rate limiting, flow control, storm control, multicast and broadcast limiting, port isolation, port mirroring, jumbo frames, and loop protection. The device is NDAA-compliant. Its polycarbonate housing and compact form factor allow for desktop, wall, DIN rail, or magnetic mounting.
