First plug the power cord into a power outlet and then plug the other end into the back of the machine. There may also be a rocker switch labeled “I” and “O”. Make sure this is set to the “I” position before attempting to power on the system.
Plug the keyboard and mouse into the corresponding ports on the back of the machine, if the keyboard and mouse have PS2 connectors (round) the ports are going to be color coded green for the mouse and purple for the keyboard. If they are USB (rectangular connectors), simply plug them into any USB ports. There should be some available right near where the round keyboard/mouse connectors are located.
Plug in the monitor’s VGA or DVI cable into the back of the machine. If your machine has onboard video in addition to an expansion video card, plug your video cable directly into the video card’s video port. If your monitor has a VGA cable and your card has a DVI connection you are going to need an adapter. This should have already been provided to you in your motherboard box or bag that came with the system. If you require one of these adapters, make sure to connect the adapter to the video card, and then plug your video cable from your monitor into the adapter. The adapter will not work if plugged into the monitor directly.
Now plug in your Ethernet (network) cable into the matching port on the back of the machine. Depending on the NIC card you may see a green and/or orange light at the port to acknowledge the connection, assuming the power supply switch is set to the “1” or on position. If you have more than one Ethernet port, use the top port if applicable.
If your system came with speakers plug the speakers into the matching green speaker port on the machine.
If you are going to use a RAID array, in most cases a driver disk must be created prior to the installation of Windows, for use during the installation. The floppy can be made using the included motherboard CD. If using Microsoft Vista or Windows 2008, these files can be loaded from a CD, but otherwise a floppy disk is needed.
