Aruba 8-port 2530-8G PoE+ switch with a 65W budget
A VoIP phone or CCTV camera may only need a 5W, so 8 x cameras/phones = 8 x 5W = 40W
However, an AP may need 15W, so the switch may only support 4 x APs = 4 x 15W = 60W
If not planned carefully and you exceed the budget, you may find devices will power up, but will have issues. So for this example, plugging a 5th AP into the 8-port switch may appear to be successful, but may result in performance issues with some or all APs.
Planning for the future…
When purchasing any new switch, we always recommend considering future changes, such as adding VoIP, CCTV technology, door access control or even IP speakers onto your network.
Often HPE Aruba switches with PoE+ ports are available at special prices (comparable to non-PoE+ versions), so it is always best to ask us before buying any switches.
