We are in a new Lennar "smart home". Media panel has an ICX 7150 C12P switch, and there are two R510 AP's installed - one upstairs, one downstairs. However, all the cables are hanging loose and not connected in the media panel. Questions: 1/ regarding the two ethernet cables coming from the R510 AP's - what ports on the switch do I plug them into? I do not know which cable comes from the Master AP, and which comes from the slave AP if that makes a difference. Is there a way to determine which of the two R510 AP's is the Master? 2/ the ethernet cable coming from the ISP - what port on the switch do I plug that into? Also - can I connect an ethernet cable coming directly from the modem to the 7150 switch, OR, am I required to install a router between the modem and the switch? 3/ if a router is not required, can I connect an ethernet cable from the modem to a TPLink 5 port switch, and then an ethernet cable from the TPLink 5 port switch to the ICX 7150 switch, and again, to which port? 4/ lastly - I have no idea whether the switch and AP's have had an initial set up and/or configuration - is that necessary and who would do that? Or, will everything "just work" after powering up and connecting all the cables? We have Comcast/Xfinity internet and will use a SurfBoard 8200 modem. I thank you for any advice and direction as to how best to connect the various cables. May I assume that once all is up and running that by using the "Unleashed" app I will be able to periodically update the firmware on the ICX 7150 switch and the two R520 AP's?? Thanks. Gary in Georgia
