Moving System Board Jumpers - NEC LS2400 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 cord 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.
