The illuminated amber LED on an expansion enclosure typically indicates a fault. In the context of Dell PowerStore expansion enclosures, an amber light can signify various issues such as power supply problems, cooling system malfunctions, or other operational faults that may affect the enclosure's performance.

When troubleshooting, the following steps are generally taken:

Identify the specific LED that is illuminated amber using the hardware documentation.

Consult the Dell PowerStore Hardware Guide to determine the exact nature of the fault indicated by the amber LED.

Follow the recommended actions provided in the guide, which may include checking power connections, ensuring proper airflow, or other hardware checks.

If the issue persists, contact Dell Support for further assistance, providing them with the details of the fault LED and any other relevant information observed.

It's important to address any faults indicated by an amber LED promptly to maintain the integrity and reliability of the storage system. The Dell PowerStore documentation provides comprehensive information on LED indicators and troubleshooting steps to help resolve such issues effectively.

When the node B embedded module fault LED on a Dell EMC PowerStore system is blinking blue and amber alternating at one-second intervals, it indicates that the node is in service mode1. Service mode is a state where the node is not in normal operation and may be undergoing maintenance or diagnostics.

In service mode, the node is typically isolated from normal storage operations to allow for troubleshooting, hardware replacement, or software updates without affecting the rest of the system. The alternating blue and amber LED is a visual indicator used by technicians to identify the current state of the node.

To return the node to normal operation, the service task must be completed, and the node must be taken out of service mode using the appropriate commands through the system's management interface. For detailed procedures on managing nodes in service mode, refer to the Dell EMC PowerStore Service Manual or contact Dell EMC Support for guidance2.

When a Dell EMC PowerStore node powers up in service mode, the commands and sequence used from the appliance SSH client to restore the node back to normal are as follows:

Run the svc_rescue_state clear command to clear the boot mode and take the node out of service mode1.

Then, run the svc_node reboot command to reboot the node and return it to normal operational mode1.

It is important to follow this sequence to ensure that the node exits service mode correctly and reboots into normal mode without any issues. For more detailed instructions or if you encounter any problems during this process, refer to the Dell EMC PowerStore Service Scripts Guide or contact Dell EMC Support for assistance1.

When shipping the system, additional stability is necessary to ensure that the equipment remains secure and undamaged during transportation. Proper stabilization prevents any potential movement or impact that could harm the delicate components of the system.

This command is used to inject a temporary root access key into the Dell EMC Data Domain system, allowing the storage administrator to have root access to perform the necessary tasks.

Based on the documentation and available commands for storage administrators, this is the appropriate command for the described scenario.
