jerryeheath,
I don't think I have ever seen a switch with a feature like that. Why would you want to do such a thing, have you found some sort of a memory leak on the switch?
Or is your concern more indirect (meaning it isn't the DES-3200-28P you want to reboot, but whatever it is powering perhaps)? If that is the case, then the common solution would be to assign a time range to the poe ports that excludes a second when you want the reboot to happen.
Either way, I can't think of any reason to want a feature like this except as a bandaid for a much more serious problem.
Good luck!
