If the router is completely powered off when you power on the power supply,

If the Routing Engine finishes booting and you need to power off the router
again, first issue the CLI request system halt command. For more information,

After a power supply is powered on, it can take up to 60 seconds for status
indicators—such as the output status LED on the powersupply, the command
display output, and messages on the LED display on the craft interface—to
indicate that the power supply is functioning normally. Ignore error indicators
that appear during the first 60 seconds.
