A . Node should be shut down for maintenance procedures
B . Hardware does not require ESD procedure
C . Node can remain online during maintenance procedures
D . Hardware does not require SolVe Desktop activity

Reveal Solution Hide Solution

Correct Answer: C
C

Explanation:

In Dell EMC PowerScale Gen 6 hardware, color-coded handles and components provide visual cues

about how to service the equipment safely.

Blue Handle Indication:

Hot-Swappable Components:

A blue handle signifies that the component is hot-swappable or hot-pluggable.

This means you can remove or replace the component without shutting down the node.

Examples of Blue-Handled Components:

Power supplies

Cooling fans

Certain I/O modules

Why Option C is Correct:

Online Maintenance:

Components with blue handles can be serviced while the node is operational.

Allows for maintenance without impacting system availability.

Why Other Options Are Incorrect:

Option A (Node should be shut down):

Contradicts the purpose of a blue handle indicating hot-swap capability.

Option B (Hardware does not require ESD procedure):

ESD precautions are always necessary when handling electronic components.

Option D (Hardware does not require SolVe Desktop activity):

SolVe Desktop provides guidance for maintenance tasks; the need for SolVe is not determined by handle color.

Dell PowerScale

Reference: Dell EMC PowerScale Hardware Replacement Guide:

Color Coding Conventions:

Explains that blue handles indicate hot-swappable components.

Maintenance Procedures:

Provides instructions for servicing components with blue handles without shutting down the node.

Safety Guidelines:

Emphasizes the importance of following ESD procedures during any hardware maintenance.

Best Practices:

Follow Proper Procedures:

Even though the node remains online, adhere to the recommended steps for replacing the component.

Use ESD Protection:

Wear an antistatic wrist strap and work in an ESD-safe environment.

Verify Component Status:

Check system logs and indicators to ensure it’s safe to remove the component.

Additional Notes:

Minimizing Downtime:

Hot-swappable components help maintain high availability and reduce service interruptions.

Consult Documentation:

Always refer to the latest Dell EMC documentation or SolVe Desktop for specific instructions.

Question #37

A platform engineer is connecting a new Dell PowerScale F600 node to the frontend switch in an existing cluster with legacy nodes.

How should the network cables be connected?

A . From the PCIe slot 1 to the frontend Ethernet switch
B . From the PCIe slot 3 to the frontend Ethernet switch
C . From the PCIe slot 1 to the frontend InfiniBand switch
D . From the PCIe slot 3 to the frontend InfiniBand switch

Question #39

A platform engineer has added an F200 node to a Dell EMC PowerScale cluster. The cluster now has five F200 nodes.

Before leaving the site, what action must the engineer perform?

A . Verify the node LNN is set to 1
B . SmartFail the node and rejoin the cluster
C . Reboot the node and wait for a green status
D . Ensure the install base record is updated

Question #40

Which Dell EMC PowerScale Gen 6 components are considered CRUs?

A . SSD, power supply, fan, and bezel
B . Back-end switch, power supply, disk drive, and bezel
C . SSD, power supply, disk drive, and bezel
D . SSD, memory card, disk drive, and bezel

Reveal Solution Hide Solution

Correct Answer: C
C

Explanation:

In Dell EMC PowerScale Gen 6 systems, components are categorized as either Customer Replaceable Units (CRUs) or Field Replaceable Units (FRUs). CRUs are parts that customers are authorized to replace themselves without the need for a Dell EMC service technician. Understanding which components are CRUs is essential for efficient maintenance and minimal downtime. CRUs in PowerScale Gen 6:

SSD (Solid-State Drive) and Disk Drive:

Both SSDs and HDDs are considered CRUs.

They can be hot-swapped without powering down the node. Customers can replace failed drives to restore full functionality. Power Supply:

Power supplies are hot-swappable and designated as CRUs.

Nodes typically have redundant power supplies; replacing one does not require shutting down the

node.

Bezel:

The front bezel is considered a CRU.

It can be removed and replaced without tools.

Serves both aesthetic and airflow management purposes.

Why Option C is Correct:

SSD: As a storage component, the SSD is a CRU.

Power Supply: Designated as a CRU for quick replacement.

Disk Drive: Refers to HDDs, also CRUs.

Bezel: Easily removable by the customer.

Why Other Options are Incorrect:

Option A: Includes fan, which is not typically a CRU in Gen 6 nodes; fans are usually considered FRUs due to the complexity of replacement and potential risks.

Option B: Lists back-end switch, which is a complex component requiring a service technician (FRU). Option D: Includes memory card (DIMM), which is generally not a CRU because replacing memory modules requires technical expertise and poses risks if not done correctly. Dell PowerScale

Reference: Dell EMC PowerScale Hardware Replacement Guide:

Chapter on Customer Replaceable Units (CRUs):

Lists the components that customers can replace.

SSDs, HDDs, power supplies, and bezels are specified as CRUs.

Safety Instructions:

Provides guidelines on how to safely replace CRUs.

Emphasizes the use of ESD (Electrostatic Discharge) precautions.

Dell EMC PowerScale OneFS Administration Guide:

Disk Management Section:

Explains how to handle drive replacements.

Details the hot-swapping procedure for drives.

Best Practices:

Before Replacing a CRU:

Verify the component has indeed failed.

Ensure you have the correct replacement part.

During Replacement:

Follow proper shutdown procedures if required (though CRUs are typically hot-swappable).

Use appropriate ESD protection.

After Replacement:

Confirm that the system recognizes the new component.

Monitor the system for any errors or warnings.
