Dell™ OptiPlex™ 760 Service Manual

  Drives

Drives

Your computer supports:

• One serial ATA (SATA) hard drive
  
  
• One 3.5-inch drive bay (to support a floppy drive or a media card reader)
  
  
• One SATA optical drive
  
  

NOTE: Due to the limited number of drive bays and controllers on this computer, you will not be able to connect all supported devices at once.

NOTE: If you will be operating your computer without an optical drive or a 3.5-inch device (floppy drive or media card reader) installed, the appropriate drive bay insert must be installed in place of the drive. Contact Dell if you need a drive bay insert.

General Drive Installation Guidelines

SATA connectors on the system board are labeled SATA0 and SATA1. Hard drives must be connected to the lower-numbered SATA connectors. Any other SATA device (like an optical drive) must be connected to the remaining SATA connectors numbered higher than the one that the hard drive is connected to. For example, if you have a SATA hard drive and a SATA optical drive, connect the hard drive to the SATA0 connector and connect the SATA optical drive to the SATA1 connector (see System Board Components for the location of the 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.

Drive Inserts

Your computer will come with a plastic insert with shoulder screws and a metal insert.

Removing Drive Inserts

1. Follow the procedures in Working on Your Computer.
   
   
2. Remove the computer cover (see Removing the Computer Cover).
   
   
3. Lift the drive release latch.
