Appendix A Power Supply Specifications
4000 W AC-Input and DC-Input Power Supplies
Table A-30 4000 W AC-Input and DC-Input Power Supplies 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 power supply is turned
off.
DC-input power supplies:
• 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.
• 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.
