3-24 Configuring Your System
Configuring System 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 jumper blocks on the I/O riser board 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.
Figure 3-2 shows the location of the system jumpers. There are two jumper
blocks on the I/O riser board that make up the system jumpers. The “Processor
Speed" jumper block and the "System Function" jumper block. Table 3-4 lists
the "Processor Speed" jumpers and their factory default settings and Table 3-5
lists the "System Function" jumpers and their factory default settings.
