Controller card power management using gNMI and gNOI

You can manage the power state of Routing Engines using the gRPC Network Management Interface (gNMI) and gRPC Network Operations Interface (gNOI) services. Use gNMI for configurations that persist across reboots, ensuring the controller card remains powered off. Use gNOI to temporarily power down a Routing Engine until the next reboot. This capability is particularly beneficial for troubleshooting and isolating faulty cards. To use the gNMI service, configure the path /components/component/controller-card/config/power-admin-state and set the value to "POWER_DISABLED" or "POWER_ENABLED" for the target Routing Engine. For the gNOI service, use the System service Reboot() RPC with the POWERDOWN or POWERUP option and specify the target Routing Engine.
