The LEDs indicate the following:
•
Input OK LED—When the power switch is turned on, this green LED should go on immediately,
indicating that the source DC voltage is within the operational range of –40.5 to –75 VDC. If the
power switch is on and the LED remains off, either the source voltage is not present or exceeds
the operational range.
•
Output fail LED—If this red LED is on, one or both of the power supply output voltages (+5 and
–48 VDC) is out of tolerance. When the power supply is first turned on, the output fail LED
blinks on and off for five seconds, then turns off. If the LED stays on, a fault has been detected
within the power supply.
