Thanks Vijay/Patrick for your comments.

The feature we are working is different from vijay's feature.

Out p= latform is multi host system and we have the host as FRU and it can b= e plugged in to a slot. The slot has an option to control slot power and th= is can be used for a AC cycle.

We pr= oposed a design to add the slot power control in the x86-power-contro= l.The earlier discussion can be found in the below link.

ed tanous,

I will create a clear document on when to use this slot power control featu= re.

Thanks,

Priyatharshan P

Hi Priyatharshan,

Chassis system reset is for removing AC power for = the whole chassis and it is already supported in x86-power-control. I am wo= rking on enabling this feature in redfish. I am not sure how it is related = to your new features. If it is related then you can also define system_reset target unit.

Regards

-Vijay

Hi V= ijay,

&nbs= p;

I am= working on a patch to support 12v slot AC cycle in x86-power-control= .This can be enabled by configuring slotACPowerName in json config file.Sin= ce you are also working on similar kind of feature in x86-power-control, I would like bring up this discussion on mai= ling list to understand how these two features, and the design you proposed= for chassis reset are intended to work together.Kindly go through my desig= n changes below and share your thoughts.

&nbs= p;

I ha= ve modified the existing /xyz/openbmc_project/state/chassis0 object to impl= ement 12V On, Off, and Power Cycle for system which has 12V Slot power supp= ort.

&nbs= p;

If s= lotACPowerName is disabled and if,

&nbs= p;

Requ= estedPowerTransition =3D "xyz.openbmc_project.State.Chassis.Transition= .Off" then poweroff [existing functionality not changed]

&nbs= p;

Requ= estedPowerTransition =3D "xyz.openbmc_project.State.Chassis.Transition= .On" then powerOn [existing functionality not changed]

&nbs= p;

Requ= estedPowerTransition =3D "xyz.openbmc_project.State.Chassis.Transition= .PowerCycle" then PowerCycle [existing functionality not changed]

&nbs= p;

even= ts will be called.

&nbs= p;

If s= lotACPowerName is enabled and if,

&nbs= p;

Requ= estedPowerTransition =3D "xyz.openbmc_project.State.Chassis.Transition= .Off" then 12V Ac Slot Off

&nbs= p;

Requ= estedPowerTransition =3D "xyz.openbmc_project.State.Chassis.Transition= .On" then 12V Ac Slot On

&nbs= p;

Requ= estedPowerTransition =3D "xyz.openbmc_project.State.Chassis.Transition= .PowerCycle" then 12V Ac Slot PowerCycle

&nbs= p;

even= ts will be called.

&nbs= p;

Than= ks,
