For server models that have hot-swap redundant power supply module(s), there might be one or two power
cord connectors 1 on the rear of the server. For each hot-swap redundant power supply module, there
might be one or two status LEDs on the power supply module near the power cord connector. When the
green LED is lit, it indicates that the hot-swap redundant power supply module is working correctly. When
the red LED is lit, it indicates that the hot-swap redundant power supply module has failed.
