Appendix A Power Supply Specifications
8700 W AC-Input Power Supply
Table A-39 8700 W AC-Input Power Supply LEDs
LED Meaning
INPUT OK 1, INPUT OK 2,
and
INPUT OK 3
• Green—Source 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.
220VAC 1, 2, and 3
• Green—High-line AC is present on the respective AC inputs. (Input
voltage is 170 VAC or higher.)
• Off—Source AC voltage falls below 170 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—One or more of the power supply DC-output voltages is out
of the normal operating range:
– For +3.3 VDC output: 2.7–3.0 VDC (min); 3.6–3.8 VDC (max)
– For +12 VDC output: 10.5–11.5 VDC (min); 12.6–13.0 VDC
(max)
– For +42 VDC output: 38.0–40.0 VDC (min); 45.0–52.0 VDC
(max)
• Off—All DC-output voltages are within normal operating ranges.
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.
