Changing the Jumper Settings

The hard disk drive jumpers are located on the drive’s circuit board, near the large cable socket. The jumpers on your drive may be in a slightly different location than the one shown below, but you set them the same way.

There are four positions for the jumpers on each hard disk drive. Jumpers are installed in only two of the positions and the other two positions are left open.

To move a jumper from one position to the other, use your fingers, needle-nose pliers, or tweezers to pull it off its pins and gently move it to the other position. Be careful not to drop the jumper or damage the pins as you install it.

If you are going to use only one hard disk drive, the jumpers should be set in positions C/D and ACT. If not, change them to these settings. Then see “Installing a Hard Disk in the Vertical Position,” on page B-8, for instructions on installing your first hard disk drive.
