Adding an expansion card

The system board has seven (7) expansion slot connectors. The system board accepts two types of expansion cards: ISA and PCI. Some of the PCI expansion slots are designed to allow the slot to be shared with a special purpose expansion card such as a RAIDport card.

Some ISA expansion cards have jumpers or switches that set interrupts and I/O addresses. They come with instructions that explain how to set them to avoid hardware conflicts. Follow the instructions carefully.

Refer to Figure 7 on page 14 for the installation locations.

To Install an Expansion Card

1.Set any jumpers and switches on the card, if required in the card instructions.

2.Turn off the system and disconnect the power cord.

3.Open the case (“Opening the system” on page 3), observing the static electricity precautions in “Static electricity precautions” on page 2.

4.Locate an open slot of the correct type.
