Validate the ability to toggle the power-admin-state for Fabric, Linecard, and ControllerCard components. Including negative scenario for attempting to power down both controller cards.

1. Test Setup:
   • Verify /components/component/{linecard|fabric}/state/oper-status is ACTIVE for all installed Linecards and Fabric Cards.
2. Test Logic:
   • Select one linecard and one fabric card.
   • Update /components/component/{linecard|fabric}/config/power-admin-state to POWER_DISABLED for the selected linecard and fabric card.
   • Verify /components/component/{linecard|fabric}/state/power-admin-state changes to POWER_DISABLED for the selected linecard and fabric card.
   • Verify /components/component/{linecard|fabric}/state/oper-status is DISABLED for the selected linecard and fabric card.
   • Update /components/component/{linecard|fabric}/config/power-admin-state to POWER_ENABLED for the selected linecard and fabric card.
   • Verify /components/component/{linecard|fabric}/state/oper-status returns to ACTIVE for the selected linecard and fabric card.

1. Test Setup:
   • Connect to the DUT via gNMI and retrieve the list of all available controller cards by checking components of type CONTROLLER_CARD.
   • Ensure there are at least two controller cards available on the DUT to perform this test.
   • Verify that the /components/component/state/oper-status is ACTIVE for both the controller cards.
   • Verify that the /components/component/state/switchover-ready is true for both the controller cards.
2. Test Logic:
   • Find out the PRIMARY Controller Card using /components/component/state/redundant-role.
   • Using gNMI Set, attempt to update /components/component/controller-card/config/power-admin-state to POWER_DISABLED for the PRIMARY controller card.
   • Wait until the switchover happens and the SECONDARY becomes PRIMARY.
   • Verify that the /components/component/state/oper-status of the disabled Controller Card is now DISABLED.
   • Using gNMI Set, attempt to update /components/component/controller-card/config/power-admin-state to POWER_DISABLED for the newly elected PRIMARY controller card.
   • The device should either:
     • Reject the configuration to POWER_DISABLED the controller card OR
     • Automatically enable the previously POWER_DISABLED Controller Card and then POWER_DISABLED the requested Controller Card.
   • In any case the device should not become unresponsive, unreachable or lose connectivity.
   • Restore the /components/component/controller-card/config/power-admin-state for the disabled controller card back to POWER_ENABLED via gNMI Set.
3. Verification:
   • Verify the operational status and redundant roles of the controller cards post-recovery.
