3.6 Installing the CIO-DAC## in the Computer
Turn the power off.
Remove the cover of your computer. Please be careful not to dislodge any of the
cables installed on the boards in your computer as you slide the cover off.
Locate an empty expansion slot in your computer.
Push the board firmly down into the expansion bus connector. If it is not seated
fully it can fail to work and could short circuit the PC bus power onto a PC bus
signal. This could damage the motherboard in your PC as well as the CIO-DAC##.
