Power status LEDs—ThesefrontandrearpanelLEDsindicate
thePS124statusbylightingasfollows:
• Green when power is applied and current draw is normal
• Red indicates a current overload condition
C
Continued operation in an overload condition may
cause premature power supply failure.
• Unlit when an output is shorted
N
To identify the shorted output, unplug the outputs one at
a time until the LEDs light green.
