Upgrading a sup's ROM can be done while the sup is active.  Actually having the sup use the new code will require rebooting the sup.  If you have dual sups, you can do this failing from one sup to the other.  (If you're doing both sups, don't forget to insure 1st sup being reloaded comes fully back on-line before doing 2nd.)  If you have a single sup, it will cause a hit to the whole chassis.
