Diagnostic indicators

The diagnostic indicators on the system front panel display error status during system startup.

NOTE: No diagnostic indicators are lit when the system is turned off. To start the system, plug it into a working power source and press the power button.

The table here describes system conditions and possible corrective actions associated with these indicators:

Electrical indicator The indicator blinks

amber if the system experiences an electrical error (for example, voltage out of range, or a failed PSU, or voltage regulator).

See the System Event Log to determine the HDD or SSD that has an error. Run the appropriate Online Diagnostics test. Restart system and run embedded diagnostics (ePSA). If the HDDs or SSDs are configured in a RAID array, restart the system and start the host adapter configuration utility program.

See the System Event Log or system messages for the specific issue. If it is because of an issue with the PSU, check the LED on the PSU. Reseat the PSU by removing and reinstalling it. If the issue persists, see Getting help in this document.

Temperature indicator The indicator blinks

amber if the system experiences a thermal error (for example, a temperature out of range or fan failure).

Memory indicator The indicator blinks

Make sure that none of the following conditions exist:

• A cooling fan is removed or has stopped functioning.

• System cover, cooling shroud, EMI filler panel, memorymodule blank, or back-filler bracket is removed.

• Ambient temperature is too high.

• External airflow is obstructed.

PCIe indicator The indicator blinks

Restart the system. Update any required drivers for the PCIe card. Re-install the PCIe card. If the issue persists, see Getting help in this document.

Front HDD or SSD indicator patterns

A healthy HDD or SSD LED flashes to indicate I/O activity. The Nutanix Web graphical user interface (GUI) provides a feature to help locate a specific HDD. When the front LEDs are turned on using the Nutanix Web GUI, the HDD or SSD you are trying to locate continues to blink as long as there is an I/O activity. The other HDDs or SSDs blink twice every second (in addition to blinking because of I/O activity). The HDD or SSD you are trying to locate does not blink twice every second.

If you turn off the HDDs or SSDs using the Nutanix Web GUI, LEDs blink only when I/O information is being communicated. The SSD slots, which occupy the slots, beginning at slot 0 from the factory, blink at a faster rate than the HDDs, which happens because of more I/O activity. Dell recommends that you leave the SSD in the factory installed slots so that you can easily identify their location.

Do not rely on LED lights to indicate when the HDD or SSD is offline. Do not remove a front HDD or SSD prior to the Nutanix Web GUI, indicating that HDD or SSD is ready to be removed. When the Nutanix Web GUI indicates the HDD or SSD is ready to be removed, you can replace the indicated HDD or SSD.

Green The handle or LED indicator lights green indicating that a valid power source

is connected to the PSU and that the PSU is operational.

Flashing amber Indicates an issue in the PSU.

CAUTION: When correcting a PSU mismatch, replace only the PSU with the flashing indicator. Swapping the opposite PSU to make a matched pair can result in an error condition and unexpected system shutdown. To change from a High Output configuration to a Low Output configuration or vice versa, you must power down the system.

CAUTION: AC PSU support both 220 V and 110 V input voltages with the exception of Titanium PSUs, which support only 220 V. When two identical PSUs receive different input voltages, they can output different wattages, and trigger a mismatch.

CAUTION: The PSU must be of the same type and have the same maximum output power.

CAUTION: Combining AC and DC PSU is not supported and triggers a mismatch.

Flashing green When hot-swapping a PSU, this indicates that the PSU is mismatched with

the other PSU (in terms of efficiency, feature set, health status, and supported voltage). Replace the PSU that has the flashing LED indicator with a PSU that matches the capacity of the other installed PSU.
