Setting the Jumpers

To change a jumper setting, follow these steps:

1.Refer to the illustration under “Locating System Board Components” to locate the jumpers.

2.If any option cards are installed in your computer, you may need to remove them to access the jumpers. See “Removing an Option Card” for instructions.

3.A jumper’s setting is determined by where the jumper is placed on the pins. Use the table below to identify the pin settings for 2-, 3-, and 4-pin jumpers. (To identify the pin numbers, look at the system board under the jumper.)
