Having a problem connecting servers with HP NC550SFP Nic's to Catalyst 6506.
Have servers with NC550SFP Nic's and if I plug the SFP Patch cable into a 3750 or 2960 or any other switch (Connected to this same 6506) they link up and work fine. When I plug the same SFP directly into my 6506 no link.
Also if I plug a GLC-T into the same port on my 6506 and connect it to the copper nic in above server it connects fine.
Using Cisco GLC-SX-MM SFP's on both ends.
Any help would be appreciated.
