Control
PWR Lights solid green when system is powered up. If the system
(Power) is not powered up but is connected to AC power (so that
standby voltage is available), the LED blinks green. If there
is no AC power, the LED is dark.
PRFL Blinks yellow if the speed of the power supply's internal fan
(Predictive Fail) falls below acceptable levels. Power supply has not failed, but
may do so soon.
FAIL Lights solid yellow when power supply fails. Blinks yellow
(Power Supply when power supply is drawing more current than it should,
Failure) because of a short-circuit in the power supply or elsewhere in
the server. If the short-circuit is in the power supply, the
power supply shuts down. If the short-circuit is in the server,
the server shuts down.
