Phase LEDs
Note: for single-phase Rack
PDUs, only one LED is
present.
When no alarms are present, the LED display
shows a phase current, and a green Phase LED
indicates for which phase. The system
automatically cycles through each phase,
displaying the phase current for three seconds.
If an alarm is present for one phase, the applicable
Phase LED turns on and stays on while the alarm
condition is present. The LED will illuminate orange
for a Warning alarm or red for a Critical alarm. If an
alarm is present for more than one phase, the
system will automatically cycle through each phase
with an alarm, illuminating the Phase LEDs for three
seconds.
3 LED display Shows the phase current for the currently
illuminated Phase LED.
