sorry I am new, and I would like your help for check my topology and the devices before to buy.
I would like to setup and speed network 100% manage by omada.
The internet come from WAN/LAN1. Really I will use about 9 switches but for simplify I show you only 4.
My concert is if I am usgin right the Switch SPF+ TL-SX3016F
Welcome to TP-Link Business Community!
The TL-SX3016F switch is usually used in the core layer of a middle-sized business network, while the TL-SG2210P switch is normally used in the access layer. May I know your application scenario and your purpose of the topology? What devices will be connected to the downlink TL-SX3016F switches?
If you just want to connect the ER7206 router to the first TL-SX3016F switch, you may use a Media Converter like MC200CM to replace the TL-SG2210P (with a 1G SFP slot) and one 10G SFP Cable TL-SM5220-1M.
As you may find that there is no Ethernet port on the TL-SX3016F switch, if your end clients are some Ethernet devices, you may replace the downlink TL-SX3016F switches with a TL-SG3428X or a TL-SG3428XMP (it supports PoE out). By the way, using Ethernet Cat5e or above cable should be enough.
Hope the information above helps.
