In Figure 7-4, the cover on the right side of the computer is removed to provide an interior view. Figure 7-4 also identifies the drive bays. Refer to these illustrations to locate interior features and components discussed later in this guide. The system board-the large, vertical, printed circuit board at the left side of the chassis-holds the computer's control circuitry and other electronic components. Some hardware options are installed directly on the system board. The external drive bays provide space for up to three half-height 5.25-inch drives, typically CD-ROM drives or tape drives. The diskette drive bay holds a 3.5-inch diskette drive. The harddisk drive bays provide space for up to four 1.6-inch or six 1-inch small computer system interface (SCSI) hard-disk drives. These hard-disk drives are connected to a SCSI host adapter on the system board or on an expansion card, via the SCSI backplane board. When you look inside the computer, note the DC power cables leading from the power supply. The power cables supply power to the system board, SCSI backplane board, externally accessible drives, and any expansion cards that connect to external peripherals. The wide ribbon cables are the interface cables for internal drives. For non-SCSI drives such as the diskette drive, an interface cable connects each drive to an interface connector on the system board or on an expansion card. For SCSI devices, interface cables connect externally accessible SCSI devices and the SCSI backplane board to a SCSI host adapter either on the system board or on an expansion card. (For more information, see Chapter 9, "Installing Drives in the External Bays" and Chapter 10, "Installing Hard-Disk Drives.") During an installation or troubleshooting procedure, you may be required to change a jumper or switch setting. For information on the system board jumpers, see Appendix B, "Jumpers and Switches."
