[cisco-voip] "Small" switches that can provide 48 ports

[Howard, Chad]

The price difference between 24 vs 48 ports is a lot greater on the 100M
3750's.  

The gig 3750's are only about 100 bucks more (list) to buy 2 - 24's vs.
1 - 48 port box.  Doesn't seem to be much cost issue there, but port
density might be a problem for some folks since the stack limit is still
9 switches either way.

Not sure on the maintenance.

Buying 2 switches increases your per-port cost by 17% and the ongoing
Smartnet maintenance cost by 81%; not a great deal.  If you plug in the
675W RPS, can you then run all 48 ports at max power, as long as both
primary and redundant power supplies are operating, or is it an
either-or proposition?
