[Info-vax] rx4640 power

[Snowshoe]

Is the Integrity rx4640 240 volt only? I got one and plugged it into 
120V. I could talk to the MP fine but when given the power on CM> PC -ON 
-NC it accepted the command but nothing happened.  The log says 
insufficient power.

The label on the power supply (HP 0957-2186) says it can run off 
100-127V or 200-240V, but the power output is almost twice as much at 
240V. Yet the 120V amount (696 W) should be sufficient for this box with 
1 CPU and little memory.

The HPE quickspecs mention AC Input power 200-240V 50-60 Hz, with no 
mention of 120V operation. I was wondering if that was an omission or it 
really does require 240V. In the US where I am, almost everything 1500 
watts or less runs off 120V.

Since the quickspec states a typical maximum for a fully loaded box as 
1065 watts which does exceed the 120V power supply's rating I am 
guessing it really is 200-240V only. Is this correct?
