Changing Jumper Settings
Changing Jumper Settings
The system board and the system-board jumper settings for your
model appear on a label inside your server. These values are preset.
If you need to change them, follow the instructions given below.
You will see the label when you remove the server side cover. (To
remove the side cover, go to “Preparing to Install Options” on
page 181.)
You might also need to change jumper settings on other devices,
including adapters and backplanes. Refer to the documentation that
comes with the device for specific information about the appropriate
jumper settings.
How to Set Jumpers
A jumper covers pins on a pin block. The jumper setting depends
on which pins are covered. For example, on the three-pin
administrator password jumper, you cover the left and center pins
to set the change state.
Jumper positions are indicated on the system board with the jumper
location identifier, for example J15, and the 0 or 1 symbol. The
following illustration shows the jumper on a pin block being moved
from position 0 to position 1. The orientation and labels for the
jumpers on your system board might be different from those shown
here.
To change a jumper setting:
1. Lift the jumper straight up off the pin block.
