If the switch is powering devices over the cable, the number to check is the total power budget rather than the per-port figure, because that total is shared and a full rack of cameras or phones will exhaust it long before the ports run out. Unmanaged units plug in and work; managed ones add configuration you only need if someone will use it. See networking, network cables and ethernet adapters.
