I appreciate your response, definitely helped. So I should be fine with the T620 as long as I also get a desktop switch to increase the number of available NIC ports I have, correct?

I found this POE Switch. Is this what I need? Nothing else besides the 1) T620, 2) POE switch & 3) an access point router?

I see a lot of people talking about these adapters. (or similar). Do I need this too or is this the same product as the above desktop switch?

My guess is they are the same thing.

Thank you again for your advice. I’m pretty new to this but excited to learn, just want to make sure I’m buying all the required things
