Appendix A Power Supply Specifications
3000 W AC-Input Power Supply
TableA-26 3000W AC-Input Power Supply LEDs
LED Meaning
INPUT OK
• 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.
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.
42V OK
• Green—42 VDC is present at the fan power connector.
• Off—42 VDC is not present at the fan power connector.
