6. Wrap and fasten one end of the ESD grounding strap around your bare wrist, and connect the other
end of the strap to the ESD point on the chassis.
7. Switch the AC switch in the chassis above each power supply to the on (—) position.
8. Check that the AC power supply is correctly installed and functioning normally. Verify that the AC OK
and DC OK LEDs light steadily, and the PS FAIL LED is not lit.
NOTE: After a power supply is powered on, it can take up to 60 seconds for 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.
If any of the status LEDs indicates that the power supply is not functioning normally, repeat the
installation and cabling procedures.
9. On the external management device connected to the Routing Engine, monitor the startup process to
verify that the system has booted properly.
NOTE: If the system is completely powered off when you power on the power supply,
the Routing Engine boots as the power supply completes its startup sequence. Normally,
the router boots from the Junos OS on the CompactFlash card.
After powering on a power supply, wait at least 60 seconds before turning it off.
