9. On the external management device, monitor the startup process to ensure that the
system boots properly.
NOTE: After you power on a power supply, wait for at least 60 seconds before you turn
it off. After you power off a power supply, wait for at least 60 seconds before you turn
it back on.
If the system is completely powered off when you switch on a power supply, the SRE
or RE module boots as the power supply completes its startup sequence.
After you power on a power supply, it can take up to 60 seconds for status indicators
such as power supply LEDs and the
show chassis operational mode CLI command
display to indicate that the power supply is functioning normally. Ignore any error
indicators that might appear during the first 60 seconds.
