That’s a Cisco Meraki device. It’s Enterprise grade equipment. Part of the appeal of that line of device is being able to basically just register the serial number of the device on a dashboard and the configuration that you pre-configured on the Dashboard can be automatically pushed to the device when it is powered on. In theory, it means you can basically ship it to a dinosaur of a user and ask them to plug it in and turn it on. In practice? Stuff like this happens all the time if you try to do that.

Could also be power source for PoE, if that is separate on the device. And if that is powering IP phones, and the PCs are connected to integrated switches of those IP phones, "the internet is down".
