Stage 3 Installing the disc drives

The disc drives are held in metal boxes within the case (called "caddies")
You will see that the front of your computer case has a number of removable plastic panels, with a snap off metal guard straight behind. Decide where you would like your CDROM device, and remove the plastic and metal covers. Slide the drive in from the front of the case, and fasten it in place with two screws on each side. The drive will need connecting (see end of page)

Underneath the large 5 inch drive caddie is a smaller three and a half inch one that is intended to be used with floppy disc drives and hard disc drives. Instalation is identical to the CDROM, except that the hard drive is fitted inside the case without having to remove the front panels.

This is another view of the smaller drive caddie.

The floppy drive is connected using a special ribbon cable which appears to have some of the ribbon twisted half way through the cable. Plug one end into the socket on the Motherboard, and the other into the floppy disk drive itself. The plugs and sockets should only mate one way, be careful not to bend any pins.

On this image, you will see that the spare ribbon cable has been tucked into the small drive caddie.

The other drives are connected using a system called IDE (integrated drive electronics). This motherboard has two IDE channels, and both channels can support two devices.

This image shows bothe of the IDE channels, one connector is black and the other one is blue.

Channel 1 uses a much faster system called UDMA 100. This channel has a blue connector on the motherboard, and should be used with a special UDMA100 ribbon cable. Plug the blue plug into the blue socket on the motherboard, making sure that you dont bend any pins.

The other end of the UDMA ribbon cable should be plugged into the hard drive.

You should not mix UDMA 100 devices with slower drives (normal IDE drives such as CDROMS etc) It si possible to connect two IDE drives to the same channel, and we are going to connect a ZIP drive and a CDRW drive.

This image illustrates how the ribbon cable has been folded to make its path through the inside of the case less obtrusive.

The ZIP drive is a three and a half inch device, but on this workstation it has been installed into a larger bay using a speical fixing kit. The ribbon cable is plugged into both the ZIP drive and the CDRW
