950 W AC-Input and DC-Input Power Supply LEDs
Meaning
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.
Green—Power supply fan is operating properly.
Off—Power supply fan failure is detected.
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.
