On a X460G2-48p-GE4 the SFP ports wont activate after I upgraded the firmware from 184.108.40.206 to 220.127.116.11
If I downgrade to 18.104.22.168 the port starts up again and the uplink connects to the core switch.
I checked the release notes and cannot find any info, on the logs it when I pull the sfp out and put it back in it just shows:
04/07/2015 14:42:14.33 : Media SX is inserted into Port 49
The SFP's were bought from Enterasys and used on C5 switches. The make on the SFP's are JDSU (JSP-12S0AA1) PN 52P6529
