8. Verify that the DC power source wiring from the source DC breaker to the power supply
is correct.
9. Reinstall the protective shield covering the terminal studs.

After a power supply is turned on, it can take up to 60
seconds for status indicators—such as LEDs on the power
supply,
show chassis commands, and messages on the
craft interface LCD—to indicate that the power supply is
functioning normally. Ignore error indicators that appear
during the first 60 seconds.
The Routing Engine boots as the power supply completes
its startup sequence. If the Routing Engine finishes booting
and you need to power down the router again, first issue
the CLI
request system halt command. For complete
instructions, see “Disconnect DC Power from the Router”
on page 147.
If after powering on the power supply you must power it
off, wait at least 60 seconds. After powering off a power
supply, wait 60 seconds before turning it back on.
