[c-nsp] 7600/6500 Power Supplies

Matt,

We had a problem with PS at 110V in a CAT6513. Depending how many modules 
you have, two PS at 110V will not give you redundancy you want. In our 
case, after power failure, one of Ethernet modules stops.

Can someone give me a quick real world lesson on power supplies for the 
7600/6500's?

Looking at Cisco's site it seems that most of the AC supplies will run 
on 110 or 220 volts, with the capacity being halved at 110V.

I'm planning on using a 7606 with a Sup720-3BXL, with maybe a couple 
line-cards to start. I won't be doing any POE and probably never will at 
this location. I'd like to do redundant supplies.

What capacity power supplies should I be looking at? Can I reasonably 
stay at 110V, since it's a lot easier to get in most colo facilities? Is 
there a could rule of thumb for figuring this out?

Thanks.
