Chapter 5: Installing the Controller and Disk Drives ● 35 Connecting Disk Drives to SCSI RAID Controllers 1 For each controller channel, set the SCSI ID of each disk drive to a unique number between 0 and 15. The controller is set to ID 7 by default. Although not recommended, you can change the controller ID by using the Adaptec RAID Controller utility (see page 75). Note: Do not change the controller ID unless absolutely necessary. 2 Install a terminator (or enable termination) on the disk drive at the end of each cable, or the end of the cable itself. Remove any terminators (or disable termination) on disk drives between the ends of each cable. Install your SCSI disk drives, following the instructions in your system's documentation. 3 If space inside your computer cabinet is limited, connect your disk drives to the SCSI cable before installing them. (For installation instructions, refer to your computer's documentation.) ! Caution: To avoid causing unstable operation, do not attach a cable to the controller unless the other end of the cable is attached to a least one disk drive. Alternatively, install your disk drives, then connect them to the controller. 4 When all internal disk drives have been installed and connected, close your computer cabinet, reattach the power cord, then continue with Connecting External Devices on page 35. Connecting External Devices Note: If you are not connecting any external devices, see the following section, Next Steps. 1 (SCSI controllers only) Ensure that SCSI IDs and termination are set before completing the connections to external disk drives or devices. See page 35. 2 Use high-quality cables to connect your controller to your external device(s), such as disk drives or disk drive enclosures. Adaptec recommends using only Adaptec cables. For more information or to purchase cables, visit the Adaptec Web site at www.adaptec.com.. Next Steps If you are installing the controller driver and an operating system onto a bootable array, continue with Creating a Bootable Array on page 36. If you are completing a standard installation onto an existing operating system, continue with Installing the Driver on an Existing Operating System on page 47.

Connecting Disk Drives to SCSI RAID Controllers
1
For each controller channel, set the SCSI ID of each disk drive to a unique number between
0 and 15.
The controller is set to ID 7 by default. Although not recommended, you can change the
controller ID by using the Adaptec RAID Controller utility (see
page 75
).
Note:
Do not
change the controller ID unless absolutely necessary.
2
Install a terminator (or enable termination) on the disk drive at the end of each cable, or
the end of the cable itself.
Remove any terminators (or disable termination) on disk drives between the ends of each
cable.
Install your SCSI disk drives, following the instructions in your system’s documentation.
3
If space inside your computer cabinet is limited, connect your disk drives to the SCSI cable
before
installing them. (For installation instructions, refer to your computer’s
documentation.)
Caution:
To avoid causing unstable operation,
do not
attach a cable to the controller
unless the other end of the cable is attached to a least one disk drive.
Alternatively, install your disk drives, then connect them to the controller.

When all internal disk drives have been installed and connected, close your computer
cabinet, reattach the power cord, then continue with
