Appendix A Power Supply Specifications
6000 W AC-Input Power Supply
Note The 6000 W AC-input power supply should not be used in mixed-voltage configurations. All the inputs
in a chassis must be at the same voltage (110 VAC o r 2 2 0 VA C ) .
Table A-31 shows the wattage output possible from a 6000 W AC-input power supply in redundant
mode. In redundant mode, two power supplies must have identical inputs and all inputs must be at the
same voltage. If the input voltages are mismatched, choose the value matching the weaker of the two
power supplies.
Table A-32 shows the maximum output wattage with two 6000 W AC-input power supplies in combined
mode.
Ta b l e A-30 6000 W AC-input Power Supply LEDs
LED Meaning
INPUT OK • Green—Source AC voltage is OK. (Input voltage is 85 VAC o r
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 is detected.
• Off—DC-output voltage with 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 assembly and one supervisor engine. Systems with
dual power supplies must have a minimum configuration of one
fan tray assembly, one supervisor engine, and one additional
module. Failure to meet these minimum configuration
requirements can cause a false power supply output fail signal.
