Configuring Your System
Configuring System Jumpers and Switches
This section describes the jumpers and switches used
on the I/O riser board, processor board, and system
board.
Before You Begin
Only a qualified technical person should perform the
procedures in this section.
Notice: 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 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.
Configuring I/O Riser Board Function Select Switches
This section describes how to configure and set the
function select switches for specific operating
parameters.
Caution: 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 setting switches and moving
jumpers can result in personal injury and equipment
damage.
The function select DIP switches configure the modes
of your server. Figure 4-1 shows the DIP switches that
consist of a block of four switches, accessible on the I/O
panel that is located on the I/O riser board at the rear
of the chassis.
