Calculating Power Requirements for the SRX5800
Services Gateway
The information in this topic helps you determine which power supplies are suitable for various
configurations, as well as which power supplies are not suitable because output power is exceeded. You
determine suitability by subtracting the total power draw from the maximum output of the power supplies.
Afterward, the required input current is calculated. Finally, you calculate the thermal output.
We recommend that you provision power according to the maximum input current listed in the power
supply electrical specifications (see
“SRX5800 Services Gateway AC Power Supply Specifications” on
and
“SRX5800 Services Gateway DC Power Supply Specifications” on page 62
).
Use the following procedures to calculate the power requirement:
1. Calculate the power requirement.
2. Evaluate the power budget.
3. Calculate input power.
4. Calculate thermal output (BTUs) for cooling requirements.
