Adapters and the Riser Card Your computer uses a riser card for expansion. The riser card contains expansion slots 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 slots on the riser card. For information on locating the riser card, see "Locating Components" on page 9. The riser card in your computer has two ISA slots and three PCI slots. The third PCI connector from the top shares a slot with the ISA connector directly below it. The other slots are dedicated to either the ISA or PCI bus. You can install only one adapter in the shared slot, for a total of four slots. The following illustration shows the expansion slots and connectors on the riser card.

Chassis-intrusion detection, Alert on LAN and Asset ID are available on some models only. 2. The diskette and IDE drive connectors are also on the riser card. When installing optional drives, refer to this illustration. 3. If you attach a 4-position cable connector to the 2-pin modem wakeup connector, ensure that the unused positions (of the cable connector) are next to the bottom of the riser card. If you incorrectly attach the cable connector to the modem wakeup feature, the computer might automatically restart each time you power down. Chapter 4. Working with Adapters 27

Adapters and the Riser Card
Your computer uses a riser card for expansion.
The riser card contains expansion
slots 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 slots on the riser card.
For
information on locating the riser card, see “Locating Components” on page
9.
The riser card in your computer has two ISA slots and three PCI slots.
The third
PCI connector from the top shares a slot with the ISA connector directly
below
it.
The other slots are dedicated to either the ISA or PCI bus.
You can install only one
adapter in the shared slot, for a total of four slots.
The following illustration shows the expansion slots and connectors on the riser
card.

Notes:
1.
Chassis-intrusion detection, Alert on LAN and Asset ID are available on some
models only.
2.
The diskette and IDE drive connectors are also on the riser card.
When
installing optional drives, refer to this illustration.
3.
If you attach a 4-position cable connector to the 2-pin modem wakeup
connector, ensure that the unused positions (of the cable connector) are
next to
the bottom of the riser card
.
If you incorrectly attach the cable connector to the
modem wakeup feature, the computer might automatically restart each time you
power down.
