Cause

This event occurs when the Management Locator Switch, labeled "ACK", on the back of the Ax600 slammer is depressed. By itself, the problem is harmless but should be resolved to clear the event.

The original purpose was to be used as a way to identify a system, but this functionality was never implemented.

The recessed ACK button is located on the upper left side of the PIM (Private Interface Module) just to the right of the recessed PWR button.
