Front Panel LEDs

12.6LED Boot Sequence

During the boot process, the user LEDs will change in a pattern, as described in Table 55, “LED Event Sequence”, to indicate boot progress. The user LEDs will be off by the time the CMM software is fully loaded. Once the CMM is up, the administrator can control the LED through standard interfaces or via programmatic control. The following table describes the sequence of events following the insertion of the CMM and the corresponding LED state for each event.
