Copper SFP ports won't talk to each other, will talk to other ports on switches
I've got a TL-SG3452P and a TL-SG2210MP to run a CCTV system. I need all the built-in PoE ports for cameras so I installed gigabit copper adapters in the SFP ports to interconnect the switches (cat6 is run between the locations) and connect to the DVR.
The SPF ports won't connect when plugged into each other, or to my bench LAN. Tried a straight-through and crossover cable. They do link up though when I go from an SFP to a PoE port on the other TP-Link switch. Am I missing something here?
