No you can not and this not meant to be.

The N2K is a NIC card extender. You can not connect a switch, the FEX does not run spanning tree.

See this as a solution that makes cabling to your servers easier  and provides an uplink of 40 GB

Only the Nexus 5000 series support the FEX right now.

thank you Lucien.

I think you got a right name for N2Ks, a NIC card extender.  In my opion N2K should be able to support Blade switches. Not every company has just rack mount servers, most enviroment is mixed. In my case, I run out ports on N5K, but plenty available on N2K.  I want add two more blade centers with gig switch modules in them. now I have to buy a N5K!!!.  I'm sure Cisco can make N2K to support switches too.

If you are interested the Nexus for Blade Server, there is Nexus 4000 available for IBM Blade Server.
