Calculating Power Requirements for a PTX10008
Use the information in this topic to calculate power requirements of your PTX10008 configuration and
the number of power supplies required for different PTX10008 router configurations.
CAUTION:
that you maintain n +1 power supplies in your router at all times. Replace failed power
supplies immediately to prevent unexpected failures.
If a new line card is installed in an operational router, 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 PTX10008 router configuration. The actual power consumption of your router
will be less than the calculated results shown here and will vary based on the hardware and software
configuration of your router, 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 router configurations. See
Configurations" on page
Ensure that you know the power requirements of different router components. See
