The user receives the "%sys-1-sys_overpwrrtng: system drawing more power than the power supply rating" error message on Catalyst 6500 series switches that run Catalyst OS (CatOS) software

Core issue

This message indicates that the system draws more power than the power supply rating. The power management LED is red. This condition occurs only when the system is fully configured and the Supervisor Engines draw unequal power.


The workaround is to re-seat the power supplies and then upgrade the Supervisor Engine software to a version that supports the hardware.

Refer to the Supported Hardware section of the Cisco Catalyst 6500 Series Switches Release Notes for the relevant release.
