Do you put dual Sup's in the switches?  Ie, how do you handle the scenario
of software upgrades (doesn't the whole switch have to go down to do this
type of maintenance, or do you not do that sort of thing) or switch
malfunctions?  Is it a safe bet to put so many customers and links into one
box? Or are you actually using multiple switches?
