I think this relates to the power supplies.  I noticed 'Version 1' and
'Version 2' power options in the specs a few weeks ago.  When I asked our
SE he told me V1 has 3 power modules, V2 has 4.  The difference is
essentially to provide more headroom in the event of one of the modules
failing.  Apparently V1 can just about do a fully loaded chassis with 2
modules.

My bad. Yes, I knew about the power shelves/supplies, just didn't know 
that they were reflected in the chassis ID as well.

What other options we have to draw network diagrams other than visio and edraw max ?

Depends on how fancy you want the diagrams to look.

For Linux (free), there's Dia.
For OSX (not free), there's Omnigraffle.

Omnigraffle is a nice option.

For Q&D diagrams, there's also gliffy.

I would use omnigraffle if you want something predictably laid out. You can also use graphviz if you want something to automatically lay out hundreds or thousands of nodes.

omnigraffle uses graphviz as its layout engine, and can read .dot files
directly.

Yup, but graphviz if you want something on a linux box, or something where you can make a fancy CGI with ImageMaps, etc.. to make them context clickable and interactive if you are so daring :)
