If the LED is on and then turns off during system boot, then the
system status is normal.
If the LED continues blinking or stays on, it indicates the system is
not able to shut down properly. When the chassis Inhibit switch is in
the Manual position, a controller shutdown results in a Microsoft
Windows shutdown; however, the controller is not able to shut
down the chassis power supply. As a result, the LED remains on
until the chassis Inhibit pin is pulsed low (thus cycling the power
supply) OR the chassis power button is pressed again causing
Microsoft Windows to reboot.
