General Installation Guidelines for SATA Devices
SATA connectors on the system board are labeled SATA0, SATA1, and SATA2.
Hard drives must be connected to the lower numbered SATA connectors, while any other SATA devices (such as an optical drive) must be connected to the
remaining SATA connectors numbered higher than the one that the hard drive(s) is connected to. For example, if you have two SATA hard drives and one SATA
optical drive, connect the two hard drives to the SATA0 and SATA1 connectors, and connect the SATA optical drive to the SATA2 connector. (See System Board
Components for the location of SATA connectors on the system board.)
Connecting Drive Cables
When you install a drive, you connect two cables—a DC power cable and a data interface cable—to the back of the drive.

General Installation Guidelines for SATA Devices
SATA connectors on the system board are labeled SATA0, SATA1, SATA2, and SATA3.
Hard drives must be connected to the lower numbered SATA connectors, while any other SATA devices (like an optical drive) must be connected to the
remaining SATA connectors numbered higher than the one that the hard drive(s) is connected to. For example, if you have two SATA hard drives and one SATA
optical drive, connect the two hard drives to the SATA0 and SATA1 connectors, and connect the SATA optical drive to the SATA2 connector. (See System Board
Components for the location of SATA connectors on the system board.)
Connecting Drive Cables
When you install a drive, you connect two cables—a DC power cable and a data interface cable—to the back of the drive.

Connecting and Disconnecting Drive Cables
When removing a cable with a pull-tab, grasp the colored pull-tab and pull until the connector detaches.
When connecting and disconnecting a cable without a pull tab, hold the cable by the black connector at each end.
Hard Drive
The OptiPlex 960 mini-tower chassis support either one or two 3.5-inch hard drives, or one or two 2.5-inch hard drives. If a single hard drive is installed, it may
be a 3.5-inch or 2.5-inch hard drive. When installing a second hard drive, the hard drive being installed must be he same type (3.5-inch or 2.5-inch) as the
drive in the chassis.
CAUTION: Before working inside your computer, read the safety information that shipped with your computer. For additional safety best
practices information, see the Regulatory Compliance Homepage at www.dell.com/regulatory_compliance.
CAUTION: To guard against electrical shock, always unplug your computer from the electrical outlet before removing the computer cover.
NOTICE: To avoid damage to the drive, do not set it on a hard surface. Instead, set the drive on a surface, such as a foam pad, that will
sufficiently cushion it.
NOTICE: When handling 2.5-inch hard drives, avoid pressing on the metal side (drive label). This can cause serious damage to the drove.
NOTE: For systems configured for RAID operation, removing or adding a drive may affect the RAID configuration. Refer to the Dell™ Technology Guide for
more information.
Removing a Hard Drive
The drive to be removed may be a 3.5-inch hard drive installed in the upper drive bay or lower drive bay, or 2.5-inch hard drive in the upper bay, and may be a
primary drive or secondary drive.
The upper drive bay always contains the primary hard drive, and, if a drive is installed in the lower drive bay, it is always configured as a secondary hard drive.
When two 2.5-inch hard drives are installed in the system (as primary and secondary drives), both are mounted on the same 2.5-inch hard drive caddy and it
is installed in the upper drive bay.

General Installation Guidelines for SATA Devices
SATA connectors on the system board are labeled SATA0, SATA1, and SATA2.
Hard drives must be connected to the lower numbered SATA connectors, while any other SATA devices (like an optical drive) must be connected to the
remaining SATA connectors numbered higher than the one that the hard drive(s) is connected to. For example, if you have two SATA hard drives and one SATA
optical drive, connect the two hard drives to the SATA0 and SATA1 connectors, and connect the SATA optical drive to the SATA2 connector. (See System Board
Components for the location of SATA connectors on the system board.)
Connecting Drive Cables
When you install a drive, you connect two cables (a DC power cable and a data interface cable) to the back of the drive.
