If the system is completely powered off when you power on the power
supply, the Routing Engine (or RCB) boots as the power supply completes
its startup sequence. If the Routing Engine finishes booting and you need
to power off the system again, first issue the CLI request system halt
command.
After a power supply is powered on, it can take up to 60 secondsfor status
indicators—such as the status LEDs on the power supply and the
show chassis command display—to indicate that the power supply is
functioning normally. Ignore error indicators that appear during the first
60 seconds.
10. On the external management device connected to the Routing Engine, monitor the
startup process to verify that the system has booted properly.
