Moving System Board Jumpers - NEC MC2400 User Manual

Moving System Board Jumpers

Before doing the procedures in this section, make sure that
your system is powered off and unplug the AC power cords
from the back of the chassis. Failure to disconnect power
before moving the jumpers can result in personal injury and
equipment damage.
Observe static precautions. Use an antistatic wrist strap.
To configure the system board options:
1. Power off the system and remove the left panel as described in Chapter 4 of
this guide.
2. Check to ensure the system power cord is removed from the back of the
system.
3. Locate the position of the jumpers on the system board you are changing. To
change a jumper setting, use a pair of needle-nose pliers or your fingers to
remove the jumper from its current location. Position the jumper over the
two pins for the desired setting and press it onto the pins. Be careful not to
bend the pins. Refer the System Board Summary table for system board
jumper settings.
4. Install the system cover and power up the system.
