Just closed on the new house today, and I got to really explore. The good news is that the house is pre-wired for ethernet (huzzah!). The ethernet (and coax) all come into this neat little patch panel in the laundry room: View attachment 99660 View attachment 99658 That's a netgear 8 port switch there at the bottom, which appears to plug into one of these https://www.homecontrols.com/OpenHouse-DataTelecom-Termination-Hub-LNH629 (Top right) I am NOT a networking person, so while this is VERY cool, it's new territory. A few questions: 1) the lunatic that set this up does not appear to have labelled these ethernet cables in terms of where they go. (ONE is labeled "den"). To figure out where they all go, I assume I will need one of these: https://www.amazon.com/gp/product/B01M63EMBQ/ref=ox_sc_act_title_1?smid=A1H9NMCPZH97BO&psc=1 Also, what is that white box thing on one of the ethernet cables? 2) Bottom left, there are two AC plugs. One has a power cord for the switch. The other is a wall wart with a coax out that goes into the top left coax junction box. Are they just using the coax for power instead of a normal wire? WTF? 3) That adapter is pretty warm. Is there a way to add some cooling to this little cabinet? 4) Not knowing networking well, can I run like this: Modem ....router (Google WiFi 3 pack)...wall.....ethernet switch in patch panel... wall......ethernet switch (to PC and Drobo)? I.e., is there any reason why you can't have a switch behind a switch? 5) Finally, this is [H], what else can I do with this setup that I don't know about? I've had one of these laying around, and I've been trying to decide if there is anything I can do with it.
