Powering On a DC-Powered SRX5400 Services Gateway

To power on a DC-powered services gateway:
1. Verify that an external management device is connected to one of the Routing Engine ports (AUX,
CONSOLE, or ETHERNET).
2. Turn on the power to the external management device.
3. Verify that the power supplies are fully inserted in the chassis.
4. Verify that the source power cables are connected to the appropriate terminal: the positive (+) source
cable to the return terminal (labeled RETURN) and the negative (–) source cable to the input terminal
(labeled –48V).
5. Switch on the dedicated customer site circuit breakers to provide power to the DC power cables. Follow
your site's procedures.
6. Check the INPUT OK LED is lit steadily green to verify that power is present.
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. 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.
9. Move the DC circuit breaker on each of the 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.
If the power supply is not functioning normally, repeat the installation and cabling procedures.
