Adding N2K's to existing N5K's - can't ping devices

[HotdogNeck]

Hi.  I have several cabinets with top-of-rack N2K's attached to N5K's via FEX's.  9 cabinets with 2 switches each. 

Recently I added 3 more cabinets to the mix, for a total of 12 cabinets with 2 switches each.

I can get into the new switches and see the FEX's and configure ports, etc. but no device I attach to the 'new' N2K's is pingable over the network.  I can take the same device, same cable, and attach it to a legacy N2K talking to the same N5K's, and it immediately joins and is pingable over the network.

Any tips/advice would be appreciated.  Thanks.

Hi,

Are all your 2Ks (including the new once) are the same models?

Yes, they are all the same model (Nexus 2248TP).  Purchased at the same time, but the 'new' N2K's are being added now, a year later.
