1400 W DC-Input Power Supply LEDs
LED
Meaning
INPUT OK
•
Green—Source DC voltage is OK. (Input voltage is –40.5 VDC or
greater.)
•
Off—Source DC voltage falls below –-33 VDC, is not present, or
the power supply is turned off.
FAN OK
•
Green—Power supply fan is operating properly.
•
Off—Power supply fan failure is detected.
OUTPUT FAIL
•
Red—Problem with one or more of the DC-output voltages of the
power supply is detected.
•
Off—DC-output voltage with acceptable margins.
In-line PWR
•
Green—–48 VDC passthrough output voltage is enabled and is
greater than –39 VDC and less than –60 VDC.
•
Off—Indicates any of the following:
–
Passthrough breakers are not enabled
–
DC input is less than –40.5 VDC
–
One or more –48 VDC outputs is less than –39 VDC
•
Amber—Passthrough breakers are enabled and input voltage
exceeds –60 VDC
