ISA and PCI adapters: The server uses a riser card for expansion. The riser card contains expansion slot connectors that connect adapters to the industry standard architecture (ISA) and peripheral component interconnect (PCI) buses. You can install a variety of adapters in the expansion slot connectors on the riser card. For information on locating the riser card, see "System board illustration" on page 142. For an illustration of the expansion slots that are located on the rear of the server, see "Input/Output connectors" on page 94. The riser card in the server has three dedicated ISA slot connectors and three dedicated PCI slot connectors. The following illustration shows the expansion slot connectors and other connectors on the riser card.
