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, make sure
the jumpers are set in positions
C/D and ACT. Then see
“Installing a Hard Disk in the Vertical Position” on page 7-7
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,
it is easiest to install the drive in the horizontal drive bay
first. See “Installing or Removing a Drive in the Horizontal
Position” on page 7-19 for instructions.
