So I picked up a 6248 used (on a budget) and some finsar 850nm 10Gb SPF+ transievers.
The switch came with 2.x.x firmware and I updated it to the latest 3.3.13.1 firmware in order to get things caught up, apply some patches, ect.
Updates went well and without error.
The problem I'm having is that I'm unable to link between the switch and any of my servers. Everything else seems to work on the switch but the fiber.
I've checked the Web GUI diagnostics and it says on one of the ports, "Loss of signal - No". The only other fiber I have connect at the moment says, "Yes"
So in the process of troubleshooting I just wanted to see if it would link to itself. Sure enough the link/act lights lit and I was seeing activity. But still no link to the servers.
One server is a PowerEdge 2950 and the other a SuperMicro. I don't recall what fiber card the PowerEdge has but it is the server that's giving me the "Loss of signal - No".
My SuperMicro has a SPF adapter card and the same model of SPF+ module as the switch. I even tried rotating them around and still nothing.
I'm pretty much at a loss here. I'm not quite sure what else to do.
I've tried disabling auto negotiate, manually setting speeds, ect. Nothing gets me a link.
Any help would be appreciated.
