Installing an SRX5400 Services Gateway DC Power Supply

NOTE: The SRX5400 Services Gateway and SRX5600 Services Gateway use the same power
supply model.
To install a DC power supply:
1. Ensure that the voltage across the DC power source cable leads is 0 V and that there is no chance that
the cable leads might become active during installation.
2. 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.
3. Switch the circuit breaker on the power supply faceplate to the off position O.
4. For a DC power supply, check the setting of the input mode switch. Use a sharp, nonconductive object
to slide the switch to the desired position. Set the input mode switch to position 0 for 60-A input or
position 1 for 80-A input. This setting is used by the power management software and must be set on
the power supply. See Figure 102 on page 240.
