3 How to Install Accessories Inside Your PC Installing Disk Drives Installing a Hard Disk Drive The computer has an integrated SCSI controller and an integrated Enhanced IDE controller. • The Enhanced IDE controller supports up to four IDE devices: Ì two IDE devices can be connected to the Primary Channel cable (connected to the grey connector on the system board) Ì two IDE devices can be connected to the Secondary Channel cable (connected to the red connector on the system board) • The SCSI controller supports up to seven SCSI devices (up to four SCSI devices can be connected to the internal SCSI cable). Before Installing an IDE Hard Disk Refer to the drive's installation guide to see if you must set jumpers or if there is a special installation procedure to follow. Before Installing a SCSI Hard Disk NOTE If you are installing an additional SCSI drive you must select a SCSI address for the new drive. SCSI addresses range from 0 to 7, with SCSI address 0 used by the first SCSI drive and SCSI address 7 reserved for the integrated SCSI controller. You do not need to select a SCSI address for Plug and Play SCSI hard disks (SCSI hard disks that support the SCAM protocol). You should assign an unused SCSI address to the second SCSI hard disk drive (for example, SCSI address 1). The SCSI address is usually configured with jumpers on the SCSI hard disk drive. Refer to the installation guide supplied with the drive for information on selecting a SCSI address. Some SCSI disk drives may have termination resistors that must be removed or disabled before installation in your computer. Refer to the drive's installation guide for more details and to see if there is a special installation procedure to follow. English 55
