7. If power is not present:
•
Verify that the fuse is installed correctly and turn on the breaker at the battery distribution fuse board
or fuse bay.
•
Check the voltage with a meter at the terminals of the power supply for correct voltage level and
polarity.
8. Attach an ESD grounding strap to your bare wrist, and connect the strap to one of the ESD points on
the chassis.
9. Move the DC circuit breaker on the DC power supplies to the on (|) position.
10. Verify that the BREAKER ON LED is lit green steadily.
11. Verify that the PWR OK LED is lit green steadily, indicating the power supply is correctly installed and
functioning normally.
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 .
12. 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 services gateway boots from the Junos OS image on the CompactFlash card.
After powering on a power supply, wait at least 60 seconds before turning it off.
