X = jumper installed

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-7 for instructions on installing

your first hard disk drive.

If you’ll be using two hard disk drives, you have a total of

four jumpers for eight jumper positions. Two jumpers are

included with each drive. Install three of the jumpers on the

master drive in positions C/D, DSP, and ACT. Install the

fourth jumper on the slave drive in position ACT.

If you are installing both of your hard disk drives at one time,

you should install the drive in the horizontal drive bay first.

See “Installing or Removing a Disk Drive in the Horizontal

Position” on page B-27 for instructions.
