PoE Network Switch?
I have a panel containing all my ethernet runs to my entire house. I'm going to add a network switch to this panel to facilitate the internet getting to all the rooms. There is not a plug within the ...

Few comments:
- You talk about a network layout like
Modem -> Network Switch (PoE) -> Network Switch (Non-PoE)Is this Modem a modem+router, or do oyu intend to add a NAT router somewhere in this environment? If yes - how?
- Technically you can power a GS108Tv3 - a rare switch model which has one port ("PD port") that can be powered from a PoE switch. It does not matter where the PoE switch (or even just a standards compliant PoE inector) is located, this can be on the modem/router side, or from any other room where the cables are going to.
- It's possible such switch models might not be available in the future for a replacement
- If you intend to update the network to Multigig (with 2.5/5G or even 10G) one day, not aware auch PoE/PoE+/PoE++ powered switches exist today.

I have an AT&T Fiber modem and also a Netgear Orbi RBK23 system.
Sounds like I would plug in a PoE switch into my router. And then connect the GS108Tv3 with the PoE switch. The GS108Tv3 would get it's power from the PoE switch and not need an additional power source. Did I follow correctly?
Is there a certain PoE switch that I would need to power the GS108Tv3? Extremely light understanding but PoEs have different port power ratings?
Thanks.

Correct.

The GS108Tv3 does require plain standard IEEE 802.3af PoE. A IEEE 802.3af PoE or a IEEE 802.3at PoE+ power injector is perfectly sufficient (about 20 USD including power supply), unless you need a switch with more LAN ports near the router anyway. Watch your step - don't buy any of these passive or proprietary models.

Thanks a LOT for the help. All this stuff is over my head, but I think I'm tracking. It's a pain that I can't ask Netgear directly. You'd think they'd help sell their own products...
Actually I do need a few more ports next to my router. Maybe a 5 port switch there would be helpful? Any that you recommend that you be able to power the GS108Tv3 further down the chain?
Thanks again!

And would this work for the GS108T? Not sure it's v3 but I do see the PoE - PD Port.

Also any solutions if I needed one more port? Ironically I think I need 8 ports (ethernet going to 8 different places in the house) but with the ethernet coming into port 1, I'll be down one slot.

The switch selection depends on whatever you operate or intend to operate on your network. Should there be (or come) for example Sonos in the game, I strongly suggest to look for a switch with STP/RSTP support to match the GS108Tv3, so probably another (now AC-powered) GS108Tv3.
The "last resort" could be the bespoken injector and a whatever non-poE switch.
