This issue might be seen if the following conditions are met:

1. On Junos OS Evolved PTX10003 platforms
2. When Telemetry streaming for power usage.

The value of the openconfig/components/component/*/properties/property/power_input1_usage/state/value telemetry path reported “unknown”

This is addressed from the 23.4R2 onwards.

After the fix:
