3750-X - SFP-H10GB-CU1M - Not Supported?

Unanswered Question
Aug 12th, 2010

I have 4 3750-X switches with the latest IP BASE IOS of 12.2(53)SE2 which have the C3KX-NM-10G= module in them.  They are configured in two seperate stacks and when I plug in the SFP+, I get that the module is not supported?  However all the equipment is on the supoprted DataSheet for the product, is this a bug or will the units need to be upgraded to LAN base for the hardware to be recongnized?

thanks in adance!

I have this problem too.

All the equipment came directly from Cisco, Demo Depot, for evaluation purposes.  However the cables are made in China!, well what isn't anymore! :-) 

Thanks for your response

Hi Jean,

Thanks for the information (+5).  I understand that Cisco is a very, very large organization but I would like to ask and request if someone can update the documentations to reflect this?

Thanks for the information.  I will try to reach back to Cisco for updated cables, however the updating of the datasheet would be beneficail to Cisco.
