How to Calculate the Power Consumption of Your QFX10016 | 173
How to Calculate the Number of Power Supplies Required for Your QFX10016 Configuration | 176
Use the information in this topic to calculate power requirements of your QFX10016 configuration and
the number of power supplies required for different QFX10016 switch configurations.
CAUTION: To ensure adequate power and to avoid raising a power alarm, you must
maintain a redundant power supply in your device at all times. This additional power
supply provides for the recommended
n +1 redundancy.
Replace failed power supplies immediately to prevent unexpected failures.
If a new line card is installed in an operational switch, power management does not
power on the line card if the increased power demand exceeds the total available
power, including redundant power. If redundant power is used to power on the line
card, a minor alarm is raised, which becomes a major alarm in five minutes if the
condition is not corrected.
NOTE: The calculations in this topic represent the maximum power requirements that you need
to budget for your QFX10016 modular switch configuration. The actual power consumption of
