HP MSA controller remote management?

Here's our problem, the data center loses power, and is running on the UPS batteries.  We have 45 minutes to bring the devices down before the batteries runs out of power.

How can we shutdown the MSA1000 controller and the disk drives the controller manages remotely?

I've done some reading on using Insight Manager, but I don't find anything on being able to power off an MSA controller. Can you shut it down using Insight Manager?

 I've also done some reading on the MSA1000, it mentions that the only way to really stop the flow of power to it is to unplug it.  I've read the CML manual and I don't find a shutdown command.  Can you shut it down from the command line?

And once it's shutdown can you power it up remotely?  Seeing how it doesn't really lose power unless it unplugged, I'm hoping you could power it up.

The shelves that house the disk drives, I don't remember them having a power button.  I think we just unplugged them to shut them down.  Is there some kind of device we could plug them into that could manage powering them off and on?

While we have a Liebert UPS to manage power to the data center, we don't have a generator to back it up.  When the power company kills the power for 12 hours, not much you can do without a generator.
