Verifying Power Configuration and Use on page 385
Verify on an EX8200 switch:
What the power redundancy and line card priority settings are
Whether the N+1 or N+N power requirements are being met
Whether the switch has sufficient power for a new line card or an N+N configuration
Enter the following command:

The switch is configured for N+N redundancy. As shown by the
(Redundant case)
field, the switch has sufficient power to meet the N+N power
requirements and has an additional 420 W available. The switch has insufficient power
for an additional 8-port SFP+ line card while maintaining N+N redundancy, because the
line card requires 450 W. However, it does have enough power for an additional 48-port
SFP line card, which requires only 330 W. The 8-port SFP+ line card in slot 6 has a higher
power priority than the 48-port SFP line card line card in slot 5.
