4-4 Adding Expansion Devices
Connecting USB devices is easy. You don’t need to turn off the system to
connect or disconnect the devices. Simply match the connectors on the
USB cable to the USB port on your system and the port on the USB
device, then plug in the cable.
For multiple USB devices, plug the USB cable on the new device into a
free USB port on the existing device (many devices come with two or
more ports).
Most USB devices do not need a separate power source as they draw their
power from the system. Some high power devices (for example, USB
hubs and amplified speakers) might need their own power supplies.
PC Cards
Your system supports Type II and Type III PC cards for extending system
capabilities. All cards have a standard 68-pin connector.
Type II cards are often storage or communication devices such as Static
Random Access Memory (SRAM), Read Only Memory (RAM), Flash
Memory, modem, and Small Computer System Interface (SCSI).
Some PC cards are Type II extended cards. The extended card has an
additional physical component that protrudes beyond the normal card
size. The extension provides room for additional electronics as well as a
location for external connectors.
Type III cards are thicker than Type II cards and allow no extensions.
Type III card uses include advanced function cards with additional
features such as multimode cards (such as a combined modem and LAN
card) and small hard drive storage.
Inserting a PC Card
The system integrates two CardBus slots on the left side of the system
unit. Use the slots to insert up to two Type II PC cards, either 16-bit or
32-bit (CardBus) or one Type III card. The Type II cards can be inserted
in either or both slots. The Type III card goes in the bottom slot only, with
no card in the top slot. The CardBus slots do not support zoomed video
(ZV Port).
