I have an SG500-28P switch in my office that is currently connected to an SG500-52P switch in a server closet 15ft away, using two SFP gigabit modules. I would like to upgrade this connection to make full use of the 5G SFP ports. The switches are currently configured in standalone mode, but I could consider stacking them in the future.
I haven't had much luck finding a compatible SFP to RJ45 module that works in the SG500 switches. I'd like to stick with ethernet if possible, due to crawl space/accessibility limitations, but am not opposed to running fiber as a last resort (or if it is considerably less expensive).
I've tried a 10G module from Ipolex that claims it will work at 10G/5G/2.5G/1G speeds, but that didn't work (the switch recognized the module, but no link was established).
Any help is appreciated. Thanks!
