It appears to. From the "management guide",

Someone else just mentioned that to me privately, I hadn't
seen it before. It looks to be very similar to the SMC
box, but it's hard to tell because Dell's website gives
you virtually no detail -- perhaps you can access the
manual if you're registered on their site or something.
