Table 2. System status LED patterns
LED pattern	System status	Description
Solid green	Normal	System is functioning without any errors.
1 Hz blinking green	Issues with the system	There might be redundancy loss in the power supply or fan. The non-critical threshold has crossed due to temperature, input power to power supply, voltage, output current for main power rail from power supply, and process thermal control sensors. Power supply failure might have occurred while redundant power supply was present. There is a fault in the hard drive. The controller is unable to use all of the installed memory. The battery has failed.
1 Hz blinking amber	Fatal or unrecoverable system hardware failure	An amber LED means there has been a fatal error in the system. System failure is caused when: Critical threshold is crossed. Minimum number of fans to cool the system is not present or the fans have failed. The required number of power supply is not present in the system.
