Thanks for the clarification.Got things cleared now.
As you mentioned, I will implement chassis_system0 object for full power cycle of the
entire system, and 'chassis_systemN' [N = 1:4 for my case] to do the slot-level full power cycle in x86-power-control.

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