Got it now.<br>
<br>
Take a look at [1]. You should implement the 'chassisN' objects (in<br>
x86-power-control?) to handle the normal power sequence to each of your<br>
compute cards. I think in your case N = 1:4. You should also implement<br>
the 'chassis_system0' object, which will be a full power cycle of the<br>
entire system. Finally, you'll want to implement 'chassis_systemN'<br>
(again N = 1:4) to do the slot-level full power cycle.<br>
