Only one hub is actually present in this photo, there’s a C5 on one of the shelves. The C7 is being PoE powered in an upstairs closet alongside a Hue hub. There’s also a second C7 not featured, that lives in a detached garage.
25: Ethernet patches
24: usw-24-poe - Basically a 24 port POE switch from Unifi
23: UDMP - Unifi Dream Machine Pro
20-22: Shelf has the C5 on it, powered via a POE dongle
16-19: A drawer
5-15: There's a Raspberry Pi on here that currently runs NUT UPS, connects to a SDR dongle that I'm reading signals being broadcast from my gas and electric meter, and an instance of HomeAssistant that I don't really use. The tower is a server build from a couple of years ago, has a supermicro board. Runs ESXI with a couple of VMs - Splunk, a wireguard VM, a Teslamate VM, PacketFence, etc.
4: Just an empty power strip
3: A Cyberpower 500VA UPS (forget the SKU of this one, but it's a 1U UPS)
1-2: PR1500RT2U: A 1500VA Cyberpower UPS (I got tired of a couple of power outages this year so got myself an oversized UPS to keep me up longer)
This is mostly my network rack, though there are two HEs up there too. The rest is in a closet on the 1st floor for better coverage, Both HEs and the Arlo hub are powered with PoE splitters.
SmartThings Hub (actually don't need this anymore)
RPi4 Running Home Assistant and Mosquitto
Lower left corner is a USG-3P which goes over and feeds the USW-24-POE via SFP port
Next to that is a Unifi Switch 8 60 Watt that gets it's uplink from the other SFP port on the main switch.
The C7, SmartThings, and RPi4 all run off the Switch 8.
Also from the Switch 8 is the Cloud Key Gen 2 Plus (to the right of the Switch 8) its running the upgraded 5TB drive for our hardwired outdoor cameras.
The fiber jack is next to that.
On the patch panel is every TV in the house, access points, and cameras.
No... really just PoE. But once I committed to the 24 port switch I figured I would use it as a distribution switch and leave the UDM ports alone. Though I do plug a laptop in occasionbally for configuration.
