LEDs

The following LEDs are used to monitor the functioning of the power supply units:
•
•
On both the AC-input and DC-input power supplies, the IN LED is used to monitor the voltages received
by the platform from the power source. If the input voltages are within normal operating ranges, the
green IN LED is illuminated. If the input voltages are above or below normal ranges, the IN LED is not
illuminated.
On both the AC-input and DC-input power supplies, the OK LED is used to monitor the power supply
DC output voltages used to power the platform. The normal operating ranges for the 12 VDC output
voltage is between 11.9V and 12.1V. If the output voltages are within normal operating ranges, the green
OK LED is illuminated. If the 12 VDC output voltages are above (more than 12.1V) or below (less than
11.9V) normal ranges, the OK LED is not illuminated.
The Power A and Power B LEDs on the front panel indicate whether the corresponding power supply
unit is functioning normally.
