Peripheral Drives
The following sections provide information on internally mounted drives and cables.
Drive Cabling Considerations
This section summarizes device cabling requirements and constraints. The number of
devices you can install internally 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
IDE Requirements
An 18-inch (45.7 cm) long IDE cable that supports two drives is standard in the system.
If you install an IDE drive, we recommendplacing it in the lowest 5.25-inch drive bay to
make cabling easier.
For proper IDE operation, note the cable length specified in Figure 1-6. If no drives are
present on an IDE channel, the cable must be removed. If only one drive is installed, it
must be connected at the end of the cable.
Figure 1-6 IDE Cable Dimensions
Note: If you plan to disable the IDE controller to reuse the interrupt for that controller,
you must physically unplug theIDE cablefromthe board connector if a cableis present.
Simply disabling the drive by configuring the SSU option does not make the interrupt
available.
