Switch Enterprise Campus 48S PoE is a stackable Layer 3 switch for a 19-inch rack, with PoE+++ output, SFP28 ports and dual, hot-swappable power supplies.

Who it suits

Suits schools, office buildings and other large organisations where a network room powers many access points, cameras and other PoE devices, and where the network is expected to grow within the same rack. It is an access switch with SFP28 ports for uplinks to the backbone of the network; the ports need modules or DAC cables. It can route traffic between VLANs, so not everything has to pass through the gateway. It is managed in UniFi Network, which runs on a UniFi gateway or another host.

Good to know

  • Up to four switches can be stacked, and only switches with the same port count. A link aggregation can span the switches in a stack, with up to eight ports per LAG.
  • The 2,150 W PoE budget (at 200–240 V mains) is shared across the 48 PoE+++ ports (up to 90 W per port), so not every port can deliver full power at once. In redundant power mode, where one module can take over for the other, the budget is 950 W.
  • For four-post racks. Two-post racks need a center-mount bracket or cantilever shelf for optimal support.
