Thanks :)  Our firewall blade in this chassis isn't in production yet ..
just did a shutdown successfully on it which didn't free up power but
going to yank it and see.. should free up several amps...

It _might_ split for now, but be prepared for the possibility of strange
things happening, like modules shutting down on their own.  You may also
get warnings that the chassis can't supply all of the requested power,
so some modules will not be energized.  The slots are normally energized
in numerical order, so whatever modules you have at the end will not get
powered up if you're short on juice.

If/when you upgrade to Sup720s, I believe those slots will get priority
on power since nothing else will come up if the sups can't be energized.
