XS728T 10Gbe connection issues followup
This is just a follow up to our previous post about our issues with our XS728T switch.
We had our XS728T replaced after several of the ports would no longer negotiate a connection over CAT-6 and CAT-6a cables longer than a few meters. Firmware updates, factory reset e.t.c. did not help. After contacting support a replacement was issued. The replacement worked fine for a few days, then ports that were working fine all of a sudden stopped working, and would no longer negotiate a connection (like the last switch). A week later another port dropped off. NETGEAR Support instructed a factory reset. We did so, but this did not help.
What did help, at the suggestion of NETGEAR Support, was to go to Switching > Ports > Port Configuration, then change the Admin mode of the problematic ports from Enable to Disable, then back to Enable. After that 3 of the 4 problematic ports started working correctly and would negotiate at the full 10G. 1 port would now negotiate a connection, but only at 1G instead of 10G. I then changed the Port Speed to 1G Full Duplex and back to Auto. After this the port negotiated properly at 10G (the device must be connected when you do this otherwise it won't work).
Just wanted to put this information here in case it helps someone else.
I'm going to leave this post for a bit to see if the switch remains stable and no more ports drop offline. Hopefully this helps someone.
