Power supply error LED

When the power supply error LED is lit in amber, it indicates that there is a power supply problem. To identify the failing power supply, check the status LED near the power cord connector on the redundant power supply. When the LED is lit in green, it indicates that the hot-swap redundant power supply is working correctly. When the LED is lit in amber, it indicates that the hot-swap redundant power supply is likely to fail or has failed.
