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.

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.
