Question 72 - D-PSC-MN-01 discussion

Report
Export

A platform engineer is at a customer site to replace a failed Dell EMC PowerScale Gen 6 node. After removing the compute module, they observe lit LEDs inside the removed node.

What is the recommended response?

A.

This is not normal; they need to shut down the partner node.

Answers
A.

This is not normal; they need to shut down the partner node.

B.

There is an internal electrical fault; they should call support.

Answers
B.

There is an internal electrical fault; they should call support.

C.

The node is not yet completely shut down; they should wait.

Answers
C.

The node is not yet completely shut down; they should wait.

D.

This is normal; they should continue with the procedure.

Answers
D.

This is normal; they should continue with the procedure.

Suggested answer: D

Explanation:

When a platform engineer removes the compute module from a Dell EMC PowerScale Gen 6 node and observes lit LEDs inside the removed node, this is a normal behavior due to the design of the node's power and indicator systems.

Reasons Why LEDs Remain Lit:

Residual Power:

The node's capacitors may hold residual power for a short time after shutdown, keeping LEDs lit temporarily.

Shared Power Supplies:

In Gen 6 nodes, power supplies may be shared between paired nodes, and some components might still receive power.

Recommended Response:

Proceed with the Procedure:

The lit LEDs are expected and do not indicate a fault.

The engineer should continue with the replacement procedure as per the guidelines.

Dell EMC PowerScale Hardware Replacement Guide:

Section on Compute Module Replacement:

Notes that internal LEDs may remain lit after removal.

Confirms that this is normal and does not require additional action.

Safety Precautions:

Always ensure proper ESD protection when handling components.

Follow all recommended steps to safely replace hardware.
