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.

Questions about this item

Should I choose the 48-port model with 32 PoE+ ports or the 24-port model with 16 PoE+ ports?

The 48-port model provides 48 RJ45 ports with 32 supporting PoE+ and a 195 W power budget, while the 24-port model offers 24 RJ45 ports with 16 PoE+ ports and a 95 W budget. Choose based on how many powered devices you need to connect.

What does the 104 Gbps switching capacity mean for daily traffic?

The 104 Gbps switching capacity and 52 Gbps non-blocking throughput allow all 48 Gigabit RJ45 ports and 4 SFP ports to run at line rate simultaneously without packet loss, supporting full-duplex traffic across every connected device.

The switch has 4 SFP ports — what uplink speed do they actually support?

The four SFP ports operate at 1 Gbps each, providing fibre uplinks up to 1 Gbps; they do not support 10 Gbps SFP+ modules.
