When a platform engineer disconnects and removes the power supply from a Dell EMC PowerScale Gen 6 node, they see an LED on the inside of the compute…

In Dell EMC PowerScale Gen 6 nodes, such as the ones in the F-series, nodes are deployed in pairs

within a chassis, sharing power supplies for redundancy.

Key Points:

LED Indicator Inside Compute Module:

When a power supply is removed from one node, an LED inside the compute module may illuminate.

This LED indicates that the node is still receiving power from its pair node's power supply, ensuring

continuous operation.

Redundant Power Supply:

PowerScale Gen 6 nodes are designed with redundant power configurations.

If one power supply fails or is removed, the paired node's power supply provides power to both

nodes.

Safe Removal and Replacement:

The LED serves as a visual indicator that the node is still powered, and caution should be exercised

when handling components.

There is no immediate shutdown or time limit for replacing the power supply due to the redundancy.
