Your server model might have one or two hot-swap redundant power supplies. Each hot-swap redundant
power supply has one power cord connector
1 on the rear of the server. For each hot-swap redundant power
supply, there might be one or two status LEDs on the power supply near the power cord connector. 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.
