Connecting to a DVD-ROM
In a direct-attach connection, DVD-ROM drives are connected directly to a SAS controller
with SAS cables. The number of direct-attached devices is limited to four per SAS connector.
For more information, see Direct-Attach Connections on page 54.
You can connect SATA DVD-ROM drives to your SATA/SAS controller. There are no jumpers
or switches to set before installation. (See www.adaptec.com/compatibility for a list of
compatible devices.)
1 Install your DVD-ROM. Refer to your system’s documentation for more information.
2 Use a SAS cable to connect the SATA/SAS controller to the DVD-ROM.
3 When all devices have been installed and connected, close your computer cabinet and
reconnect the power cord.

You can use a SAS expander to connect a maximum of 128 end devices to your SATA/SAS
controller.
To install the SATA/SAS controller to a SAS expander:
1 Using the appropriate cable, connect the SATA/SAS controller to the expander’s PHY
connector.
2 Connect a cable from the expander’s PHY connector to a disk drive.
Connecting to SATA/SAS Tape Drives
You can connect internal or external SAS or SATA Tape Drives to your SATA/SAS controller.
(See www.adaptec.com/compatibility for a list of compatible devices.)
1 Connect one or more SAS or SATA tape drives to the controller. Refer to your tape drive’s
documentation for more information.
