Use the information in this topic to calculate power requirements of your QFX10008
configuration and the number of power supplies required for different QFX10008 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 QFX10008 modular switch
configuration. The actual power consumption of your switch will be less than
the calculated results shown here and will vary based on the hardware and
software configuration of your switch, the amount of traffic passing through
the line cards, and environmental variables such as room temperature.
Before you begin these calculations:
Ensure you understand the different switch configurations. See
Configurations" on page
Ensure that you know the power requirements of different switch components. See
