subrate SFP?

  Unless I missed something, iLO is always on when the machine has 
power; as such, WOL shouldn't be coming into play on reasonably modern 
HP servers.  (That said, the power draw is likely still the reason, 
although I can't readily confirm Charles' observation on my only 
rackmount Gen8.)
