"I got some more information from the marketing manager. There are two power supply configuration options available with the 1950 III and 2950 III when you order it. In the US it defaults to "Energy Smart" power supplies, which can be monitored, but if you change the configuration to "Redundant Power Supply", that includes a different power supply which can not be monitored for power and is a less efficient.Okay, I'm still not buying the story ;-) If you compare tag 9HNXM3J (1950 III) and 24SXM3J (2950 III) they have the same kind of power supplies according to the online original system configuration. PSU is "PE2950 III REDUNDANT POWER SUPPLY NO POW" or "PE1950 III REDUNDANT POWER SUPPLY NO POW". Neither has been purchased as "ES"
I update the page to show this at the bottom.
I am anticipating your next question, but go ahead and ask it. :-)"
