Installing the Controller and Drives 8 Install the controller in the PCI slot and secure the controller bracket to the chassis. For Adaptec 2020SA/2020ZCR/2025SA/2025ZCR-Insert these controllers in the supported ZCR enabled slot on the motherboard and gently press down until they click into place. They may also be secured using other means available from the system manufacturer. See your motherboard documentation for more information on your supported ZCR enabled slot. 9 Connect the computer's disk activity LED cable to the appropriate connector on the controller. See Appendix G for the location of this connector for your controller. Ensure that the positive lead of the LED cable, usually a red wire or a wire marked with a red stripe, is attached to pin 1 and the negative lead, usually a black wire, is attached to pin 2. 10 Install and connect any internal drives using the appropriate cable. Note: If you are building a RAID 5 as described in Creating a Bootable RAID 5 Array on page 2-5, you must install at least three drives. 11 Close the computer cabinet. 12 SCSI controllers only-Connect any external cables and drives to the Adaptec SCSI RAID controller. Determining the Boot Controller Note: If your system will contain two or more bootable controllers, read this section. Otherwise, skip this section. The Adaptec RAID controller supports bootable drives and arrays. The default setting of the controller and system Setup usually allows you to install and boot from either a hard drive connected to the motherboard, or from a drive or array connected to the controller. 2-4
