Yes. If you would like to hardwire additional devices to your eero network, you can connect a wired switch to one of the Ethernet ports on any eero. Once you’ve connected a switch, the eero port will configure itself automatically.
Note: Always plug the switch into your eero and not directly into your modem. eero supports gigabit Ethernet (1000 / 100 / 10 mbps) but can also work with Fast Ethernet (100 / 10 mbps) equipment.
