Item Specification
Ta b l e A-5 1300 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 assemblyand 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.
