NOTE

Flashing indicates an irregular LED pulse. Blinking indicates a steady LED pulse.

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.
