Switches

Ubiquiti UniFi switches from eight-port desktop units to rackmount Pro and Enterprise models, with and without PoE, including 2.5 GbE and 10 GbE uplinks and the Etherlighting models that show link status in the cable.
Which UniFi switch do I need? works through the three things that decide it: port count, PoE budget and uplink speed. Add up the draw of every powered device and leave headroom — a switch that runs out of PoE drops devices without warning.
