Calculating Power Requirements for an EX8208 Switch

Use the information in this topic to calculate power consumption, system thermal output, and number of
power supplies required for different EX8208 switch configurations.
Before you begin these calculations:
Ensure you understand the different switch configurations. See
page 27.
Ensure that you know the power requirements of different switch components. See
for EX8208 Switch Components" on page
If the switch contains PoE line cards, ensure that you understand the PoE power budget requirements
of each line card. See Understanding PoE on EX Series Switches.
