Specific status indicated by the LEDs
This section includes some specific conditions that are not covered in the
definition tables in the /etc/alertd/alert.conf.
Yellow intermittent Activity indicator LED
A yellow intermittent Activity LED indicates that host traffic is present.
Also, while the kernel is loading, the Activity indicator LED flashes yellow
intermittently when the disk is accessed. This condition is normal and
occurs only during boot up.
