Drive cabling considerations
This section summarises device cabling requirements and constraints. The number of
devices you can install depends on:
The number supported by the bus
The number of physical drive bays available
The height of drives in the internal bays (1-inch or 1.6-inch high)
The combination of SCSI and IDE devices
SCSI Requirements
One narrow and two wide SCSI cables are standard in the system.
All SCSI devices must be unterminated except the peripheral at the end of the SCSI cable.
Hard drives usually provide an active termination, while CD-ROM drives do not. Because
we recommend putting hard drives only in the internal bays, this means that you should
route the SCSI cable so that the last device on the cable is a hard drive in the internal bay.
