Power Balancing in Cat 6500

[mciarlo]

I need to know one CLI to indicate the power used in each WS-CAC-2500W.

The command sh power only diplay the power used in both WS-CAC-2500W.

Regards,

Martín

The modules have different power requirements, and some configurations require more power than a single power supply can provide. The power management feature allows you to power all installed modules with two power supplies. However, redundancy is not supported in this configuration because the total power drawn from both power supplies is at no time greater than the capability of one supply. Redundant and nonredundant power configurations are described in the following sections.

For more information, could you please refer the following link:
