PWR
When this green LED is on, it indicates that the SEHI is receiving power.
If this LED is off, it indicates a loss of input power. Check the input
power source (circuit breaker, fuse, etc.). If the proper source power is
present, the problem could be with the SEHI.
CPU
This LED alternates from red to green during power up. After the boot is
complete, the LED blinks green. A blinking green LED indicates normal
operation. A red LED indicates a faulty processor.
NOTE
Flashing indicates an irregular LED pulse.
Blinking indicates a steady LED pulse.
