Appendix A Power Supply Specifications
1400 W AC-Input Power Supply
1400 W Power Supply AC Power Cords
Table A-16 lists the specifications for the AC power cords that are available for the 1400 W AC-input
power supply. These power cords plug into the 1400 W PEM (PEM-20A-AC+); not directly into the
power supply. The table includes references to power cord illustrations.
Note All 1400 W power supply power cords are 14 feet (4.3 meters) in length.
Note All 1400 W power supply power cords have an IEC60320/C19 appliance plug at one end.
Table A-15 1400 W 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 is detected.
• 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.
