Richtige Antwort: C
C

Explanation:

When installing Dell EMC PowerScale Gen 6 nodes in a customer-provided rack, it is crucial for the platform engineer to ensure that the rack meets all safety and installation requirements. One of the most critical pre-checks is verifying that the rack has a full earth ground and is properly bolted to the floor.

Key Points:

Full Earth Ground:

Ensures electrical safety by providing a path for fault currents.

Protects equipment and personnel from electrical hazards.

Reduces the risk of electrical interference affecting the equipment.

Properly Bolted to the Floor:

Provides physical stability to prevent the rack from tipping over.

Essential for seismic compliance in areas prone to earthquakes.

Prevents movement due to vibrations from equipment operation or external factors.

Why This is Important:

Safety Compliance:

Adhering to safety standards is mandatory to prevent accidents.

Electrical grounding is a fundamental requirement for data center equipment installations.

Equipment Protection:

Proper grounding and securing the rack protect sensitive equipment from damage.

Minimizes downtime caused by electrical faults or physical disturbances.

Why Other Options Are Less Critical:

Option A (PDUs on Opposite Sides):

While distributing PDUs can aid in power redundancy and cable management, it is not as critical as

grounding and securing the rack.

Option B (Rack Leveling):

Leveling the rack is important for equipment alignment but is a standard step during installation rather than a pre-check.

Option D (Minimum of Two PDUs):

Having multiple PDUs provides redundancy but depends on the power requirements and design of the system.

Reference: Dell EMC PowerScale Site Preparation and Planning Guide:

Section on Rack Requirements:

Emphasizes that customer-provided racks must be properly grounded and secured.

States that racks should be bolted to the floor to prevent tipping.

Safety Precautions:

Details the importance of electrical grounding for safety and equipment protection.

Best Practices:

Before Installation:

Verify that the rack complies with all local electrical codes and regulations. Ensure that a qualified electrician has installed the grounding system. During Installation:

Check that all grounding connections are secure.

Confirm that the rack is level and stable after bolting it to the floor.

After Installation:

Perform an electrical continuity test to verify proper grounding.

Document the installation for future reference and compliance audits.
