UniFi Switch US-48-500W Switch Managed PoE+ Gigabit with SFP 500W Layer 2

This UniFi Switch is a 48-port Gigabit Managed PoE+ Switch. It has a 500W
maximum deliverable PoE, and supports 802.3 at/af and 24VDC passive PoE. With
its 48 Gigabit ports, two SFP ports, and two SFP+ port, you should have more
than choices to expand your network. It's non-blocking throughput is 70Gbps,
and switching capacity is 140Gbps. The UniFi Switch delivers the forwarding
capacity to simultaneously process traffic on all ports at line rate without
any packet loss.
Total non-blocking throughput: up to 70 Gbps for 48-port
models. Each switch port offers custom settings: port name, PoE, network/VLAN
configuration, and operation mode (switching, mirroring, or aggregate) - as
well as 802.1X Authentication and Radius VLAN support. Two SFP ports support
uplinks of up to 1 Gbps. For high-capacity uplinks, each 48-port model
includes two SFP+ ports for uplinks of up to 10 Gbps. The UniFi Switch
features auto-sensing IEEE 802.3 af/at PoE to power multiple devices on the
network. The UniFi Switch integrates seamlessly into the UniFi Software-
Defined Networking (SDN) platform to create a highly scalable, end-to-end
system of network devices across multiple locations? all controlled from a
single interface.
