SFP (SX Media) not activating on 15.7.1.4

[Tino]

On a X460G2-48p-GE4 the SFP ports wont activate after I upgraded the firmware from 15.6.2.12 to 15.7.1.4

If I downgrade to 15.6.2.12 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

Tino,

I have been looking into the issue with the 1000BASE-SX and 10/100/1000BASE-T SFPs in the Summit X460G2. Thus far in our testing the issue has only been seen when running 15.7.1.4. Engineering has been made aware of the issue.

[Tino]
