    Hard drive LED isn't blinking. In the computer unit, reseat the CPU card, Axis PCB, I/O PCB and try it again. Make sure the hard drive is plugged in to the CPU card.

    If the hard drive light still doesn't blink, remove the I/O and axis cards and try again. It won't boot but the hard drive light will blink as it tries. Seen a few times where bad I/O and Axis cards have locked up the backplane bus and kept the hard drive from blinking.

    Feel free to install a new CR2032 coin cell in the CPU card while you have access. It maintains the date & time.
