LED Name/Color Function
Power Lit when the 48 Vdc power supply is on and the output is within
(Green) specifications.
If not lit after the On/Off switch is depressed, the power supply has
detected an overvoltage or overcurrent condition.
Run Lit when console mode is terminated and system program execution
(Green) begins.
Not lit during power sequencing and when in console mode.
Fault Blinks at a slow 2-second rate during the power-up sequence and
(Amber) at a fast .5-second rate during the power-down sequence. After the
power-up sequence, it stays lit until all LSB and I/O modules have
passed self-test, and then goes out.
Being lit during normal operation indicates a blower failure, an
LSB or I/O module not passing self-test, or a power supply fault.
