I recently purchased switches to run data and phones for our office, however I'm having some issues with the SFP+ adapters not linking.
The transceivers in question are Intel branded "FTLX8571D3BCV-IT" (Intel Prod Code E10GSFPSR). I also have a few Dell "FTLX8571D3BCL" SFP's that seem to work fine.
I also have other Intel 10GbE SFP+ transceivers "AFBR-703SDZ-IN2" (also Intel Prod Code E10SFPSR) that work just fine.
The 5548P will log when the non-working SFPs are plugged in and unplugged. If I run "show fiber-ports optical-transceivers", I am able to see vital stats from the "non-working" ports, including stating that there is no loss of signal on the port. I can also watch the Input Power field and am able to tell when a fiber is connected or not. All of this is also true when the same SFPs are connected to an 8132F. Both switches are running the latest firmware available (8132F - v5.1.1.7; 5548P - 4.1.0.10).
Any ideas on what could possibly be causing these transceivers to not link and function properly?
