3-26 Configuring Your System
Configuring System Board Jumpers
Before You Begin
Only a qualified technical person should perform the procedures in this section.
! CAUTION
Electrostatic discharge (ESD) can damage the system
board. Modify the system board only at an ESD workstation.
Otherwise, wear an antistatic wrist strap attached to chassis
ground.
The system board jumpers enable you to set specific operating parameters for
your system. A jumper is a small plastic-encased conductor (shorting plug) that
slips over two jumper pins.
The “System board Jumpers” illustration shows the location of the system board
jumpers. The “System Board Jumper Configurations” table lists the system
board jumpers and their factory default settings.
