Ubiquiti Networks USW-48-POE (195W) 48-port network switch

48-Port Managed Switch with 195 W PoE

This rack-mountable Layer 2 switch provides 48 Gigabit RJ45 ports and four 1 Gbps SFP uplinks. Thirty-two RJ45 ports deliver IEEE 802.3af/at PoE+ with a total power budget of 195 W. The fanless design ensures silent operation in noise-sensitive environments. Non-blocking throughput reaches 52 Gbps with a 104 Gbps switching capacity.

Suited for PoE access points and cameras.

Network managers who need to power UniFi access points, IP cameras or VoIP phones over a single cable will find the PoE+ ports and 195 W budget convenient. The switch also supports VLANs, LACP aggregation, IGMP snooping and port isolation for traffic segmentation. Buyers requiring 10 Gbps fibre uplinks or Layer 3 routing should look at a different model.

195 W total PoE budget decides port density

The 195 W pool limits how many ports can simultaneously supply full PoE+ class power, so planners must calculate per-device draw before committing all 32 PoE ports. If the connected devices stay within the budget the switch delivers line-rate forwarding on every port at 77.38 Mpps. Exceeding the budget will cause some ports to negotiate lower power classes or remain unpowered.
