A few weeks ago the company that I work for received our Nexus 7000 (7010 to be exact) switches.  Since my team was not familiar with these switches, I decided to write some quick training docs and labs for them.  Since they where well received ( or perhaps they just do not know better ), I have decided to share them with the rest of the population.
These  docs are by no-means an end-all be-all type document on the Nexus 7000 switches, but they might be enough to get you familiar with them. They are in PDF format below:
Nexus 7000 Lab Answers ver1
Nexus 7000 Training Docs
Any questions, please let me know.
Cards 2, 3, 4, 7, 8, 9 and 10 are N7K-M148GT; cards 5 and 6 are N7K-SUP1, and cards 7 and 8 are N7K-M132XP.
There has been a recent request to post the cabling diagram, here it is to the best of my memory:

The configs for the switch and the router have been lost to time, but perhaps one day I can recreate them.
Updated March 2013:
Ron Fuller, David Jansen, and Matthew McPherson have released NX-OS and Cisco Nexus Switching, 2nd Edition recently.  Below is a link to Amazon where you can purchased this book.  It is a great addition to any technical library and covers the NX-OS in great depth.  I was also a technical review on this book.
