CH121 health indicator

The health indicator statuses of the CH121 in the E9000 are described as follows:
? Off: The compute node is powered off.
? Steady green: The compute node hardware is operating properly.
? Blinking red at 1 Hz: The compute node has a major alarm.
? Blinking red at 4 Hz: The compute node has a critical alarm.
? Blinking red at 5 Hz: The compute node is not fully inserted.
Note: It is difficult to identify the blinking frequencies of 4 Hz and 5 Hz. When the indicator is quickly blinking red, you are advised to check whether the device is properly installed and then check for alarms.
