Which situation results in a flashing blue status LED on a Cisco Nexus 7000 switch I/O module?

A module that is resetting after initial power-on displays an amber or cycling status LED pattern, not a blue beacon light, which is reserved for the operator locator function.

Ejector levers being in the out position during a reset triggers a physical seating alert, not the blue beacon LED, which cannot be activated by mechanical conditions.

A module inserted during the chassis initialization process shows an initialization or amber status LED, not a flashing blue light, because blue is assigned exclusively to the operator-activated beacon function.

Insufficient power to bring up a module causes the LED to show amber or remain off to indicate a power fault condition, which is a separate LED state from the blue beacon.

The blue beacon LED is an operator-initiated locator feature activated via the NX-OS command 'hw-module beacon module slot-number', designed to help data center technicians visually distinguish a specific module among many in a fully populated chassis. It is distinct from all automatic status LED states, which use different colors or patterns to reflect hardware conditions. Toggling this LED off requires re-issuing the command, confirming it is an intentional operator action rather than an automated response.
