Table A-5 950 W AC-Input and DC-Input Power Supply LEDs
LED Meaning
INPUT OK AC-input power supplies:
• Green—Source AC voltage is OK. (Input voltage is 85 VAC or
greater.)
• Off—Source AC voltage falls below 70 VAC, is not present, or the
PEM is turned off.
DC-input power supplies:
• Green—Source DC voltage is OK. (–40.5 VDC or greater.)
• Off—Source DC voltage falls below –33 VDC or is not present at
the PEM.
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 voltages within acceptable margins.
Note For proper operation of the OUTPUT FAIL LED, systems with
single power supplies must be configured with a minimum of
one fan tray and one supervisor engine. Systems with dual power
supplies must have a minimum configuration of one fan tray, one
supervisor engine, and one additional module. Failure to meet
these minimum configuration requirements can cause a false
power supply output fail signal.
