In Figure 6-4 the right computer cover is removed to provide interior views from the right sides. This illustration also identifies features on the front of the computer. Refer to these illustrations to locate interior features and components discussed later in this guide. When you look inside the computer, note the direct current (DC) power cables leading from the power supply. These cables supply power to the system board, small computer system interface (SCSI) backplane board, externally accessible drives, and any expansion cards that connect to external peripherals. The wide, flat ribbon cable is the interface cable for internal drives. For non-SCSI drives, an interface cable connects each drive to an interface connector on the system board or on an expansion card. For SCSI devices, two 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. 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 (see Figure 6-5). Some hardware options are installed directly on the system board. The external drive bays provide space for up to three half-height 5.25" drives, typically CD-ROM drives or tape drives. The diskette drive bay holds a 3.5" diskette drive. The internal drive bays provide space for up to six 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. During an installation or troubleshooting procedure, you may be required to change a jumper or switch setting on the system board, an expansion card, or a drive. Figure 6-6 shows the location of the system board jumpers. For more information about the system board jumpers, see Appendix B, "Jumpers and Switches," in the Installation and Troubleshooting Guide Working Inside Your Computer 6-5

In Figure 6-4 the right computer cover is removed to provide interior views from the
right sides. This illustration also identifies features on the front of the computer. Refer
to these illustrations to locate interior features and components discussed later in this
guide.
When you look inside the computer, note the
direct current (DC)
power cables
leading
from the power supply. These cables supply power to the system board, small com-
puter system interface (SCSI) backplane board, externally accessible drives, and any
expansion cards that connect to external peripherals.
The wide, flat ribbon cable is the
interface cable
for internal drives. For non-SCSI
drives, an interface cable connects each drive to an interface connector on the system
board or on an expansion card. For SCSI devices, two interface cables connect exter-
nally accessible SCSI devices and the SCSI backplane board to a SCSI host adapter
either on the system board or on an expansion card.
The
system board
—the large, vertical, printed circuit board at the left side of the chas-
sis—holds the computer’s control circuitry and other electronic components (see
Figure 6-5). Some hardware options are installed directly on the system board. The
external drive bays
provide space for up to three half-height 5.25” drives, typically
CD-ROM drives or tape drives. The diskette drive bay holds a 3.5” diskette drive. The
internal drive bays
provide space for up to six 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
.
During an installation or troubleshooting procedure, you may be required to change a
jumper
or switch setting on the system board, an expansion card, or a drive. Figure 6-6
shows the location of the system board jumpers. For more information about the sys-
tem board jumpers, see Appendix B, “Jumpers and Switches,” in the
