Issue with SFP ports as uplink ports to firewall

Eric_Fresno

I have a TZ 470 firewall connected to two (daisy chained) SWS 14-48FPOE switches. The uplink from the first switches is on the SFP port 51. The switches work as expected for passing traffic. However, I cannot get switch visibility on the firewall. It gives me a message of, "Index of the Extended Switch Instance," when I try adding the first switch to the firewall. I get the same message even if I use port 48 (copper) on the switch. Any suggestions?
