3.2 SYSTEM SETTING
Jumper pins allow you to set specific system parameters. Set them by changing the pin location of jumper blocks.
(A jumper block is a small plastic-encased conductor that slips over the pins.) To change a jumper setting, remove
the jumper from its current location with your fingers or small needle-nosed pliers. Place the jumper over the two
pins designated for the desired setting. Press the jumper evenly onto the pins. Be careful not to bend the pins.
CAUTION: Do not touch any electronic components unless you are safely grounded. Wear a grounded wrist strap
or touch an exposed metal part of the system unit chassis. The static discharges from your fingers can
permanently damage electronic components.
