Dell EMC Exam D-PSC-MN-01 Topic 3 Question 11 Discussion

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.
