I inserted a SFP-GE-T (Gigabit RJ-45) transceiver in my Nexus 5548UP and I got "access down" "SFP Validation Failed" in show interface.

According to the Cisco Gigabit Ethernet Transceivers Compability Matrix the SFP-GE-T is compatible with the 5548UP.

How do I get past "SFP Validation Failed" on a SFP-GE-T transceiver on a Nexus 5548UP?

    Silly question, have you tried reseating the module? – Zypher Dec 11 '11 at 21:52
  • Totally valid question @Zypher. Reseating doesn't fix it for me :) – Alain O'Dea Dec 13 '11 at 2:27
  • Are you sure it's not counterfeit? Did you check the serial number? – MikeyB Dec 14 '11 at 20:23

Configure the port as speed 1000 before inserting the SFP-GE-T transceiver.

If you have the transceiver inserted already, remove it and then set speed 1000 on the port. Upon re-insertion the SFP should come up :)
