Note that both ends of the daisy-chain are terminated and that the<br />
actual end of the internal daisy-chain is not the AHA-1535 SCSI<br />
host adapter, but the Philips CDD2600 drive. Also note that some<br />
SCSI devices support different types of cables.<br />
Use the worksheet shown in Figure 4.12 to help you plan your SCSI<br />
cabling and physical layout. Start with the host adapter card. Figure<br />
4.13 shows a completed worksheet.
