At least one power supply is supplying power to the system.
One of the following conditions has occurred: power-supply failure, EMM failure, cooling-module failure, over-temperature condition, split-bus module not
installed, or firmware currently being downloaded. For more information, see
The system is configured for cluster mode. For more information, see
The system is configured for split-bus mode. For more information, see
An over-temperature condition has occurred (the system will shut down when the temperature inside the box exceeds 50°C [122°F]). For more
