Card connector and jumper information
Identifying adapter card connectors
You can install low-profile PCI adapter cards into the card connectors on the system
board. Use the following table to help you determine the type and length of adapter
cards that you can install in the card connectors.
Refer to the section ”Adding and removing adapter cards” on page 8-4 for
instructions on adding or removing cards.
Setting a jumper
When you install an adapter card, you may have to set switches or move jumpers to
make the card work properly. Plug and Play cards normally require no changes, but
other cards might. Refer to the documentation that came with the new hardware to
determine if changes to jumper or switch settings are required.
The following figures show how to set a jumper. Position A shows closing pins 1-2
while position B shows closing pins 2-3. Pin 1 of a jumper is usually marked by a
solid white line beside the pin.
