Configuring System Jumpers

Before You Begin

Only a qualified technical person should perform the procedures in this section.
Electrostatic discharge (ESD) can damage the system
boards. Modify system boards only at an ESD workstation.
Otherwise, wear an antistatic wrist strap attached to chassis
ground.
The jumper blocks on the PCI board located in the PCI module (one PCI board
per PCI module) 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 3-1 shows the location of the system jumpers.
