About administering APC power controlers

My main problem with masterswitch is that if you plug it into one
of the APC ups's, say the RM 3U 2200VA, that when I plug in 3-4
dual athlons, I overload the maximum per outlet of the UPS and it
powers off.

>From what I can tell the APC RM3U 2200 VA has a much lower (than 2200 VA)
threshold per outlet.  Making the masterswitch pretty much useless for
our setup.

I'd recommend some other powermanagement for 72 nodes, or putting up
with a higher granularity by turning ups's on/off via serial or network
interface directly to the UPS.   Definitely check that you can control
as many nodes as you want and still be able to plug into the UPS
of your choice.
