SFP+ Non-qualified pluggable media present Question on S4810

Hi we have some S4810 switches in our DC.

We are getting some packet loss messages from our alerting system.

Looking at the server we cant see any issues.

On looking at the switch using the show interface command 

We are seeing the following Non-qualified pluggable media present, SFP+ type is 10GBASE-CU2M

Should we be worries about this ? or should the DAC be replaced ?

The DAC's are not dell branded could someone point me to a compatibility list for the SFP+'s for the S4810 Force10 switches.

 

Switches are running 9.11(2.6)
