Chapter 5: Installing the Controller and Disk Drives ● 44 7 Thread the tie-backs through the slots on the cap card and fix to the selected location on the computer chassis. The tie-backs should completely encircle the cap card to ensure that it is held in place securely, as shown at right. Be careful not to restrict air-flow through your system. 8 Connect your computer's disk activity LED cable to the LED connector on the controller (marked on the figures in About Your RAID Controller on page 17). 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. 9 Connect your RAID controller's I2C connector to an I2C connector on an internal backplane or enclosure, using an I2C cable. For more connection details, see About Your RAID Controller on page 17. 10 Prepare and install your internal disk drives, following the instructions in Connecting Disk Drives to Your Controllers on page 44. If you are not installing internal disk drives, close your computer cabinet, reattach the power cord, then continue with Connecting External Devices on page 48. Connecting Disk Drives to Your Controllers You can connect SAS disk drives, SATA disk drives, SATA Solid State Drives (SSD), and Adaptec MaxIQ Solid State Drives to your SAS RAID controller. (See www.adaptec.com/ compatibility for a list of compatible disk drives.) There are no jumpers or switches to set before installation. If you plan to build a bootable array using internal disk drives, ensure you install at least the minimum number disk drives required to support the RAID level you want. See page 37 for more information. Note: Although you can connect both SAS and SATA disk drives to your SAS controller, we recommend that you not combine SAS and SATA disk drives within the same array or logical drive. See page 79 for more information. You have two connection options: ● To connect directly to the controller, see the following section. ● To connect to a backplane, see page 45. To connect Adaptec MaxIQ SSDs or other SSDs to your controller, see page 46. Connecting Directly to the Controller In a direct-attach connection, SAS or SATA disk drives are connected directly to a SAS card with SAS cables. The number of direct-attached disk drives is limited to four per internal SAS connector. (For more information about direct-attach connections, see page 82.) 1 Install your internal SAS or SATA disk drives, following the instructions in your system's documentation.
