System Overview 1-13
AC Power Adapter and AC Power Cord
System DC power comes from the AC power adapter. A converter built into the
AC power adapter converts 110 to 230 Vac power to the DC power necessary
for system operation. The AC power adapter provides 90-watts of power for
system use.
The AC power cord plugs into the AC power adapter and a 115 Vac or 220 Vac
power source. The adapter’s DC power cord plugs into the system’s DC power
connector at the back of the system.
The DC power connector locations on the system board are given in Section 4,
“System Board.” Power supply specifications are in Section 9, “Specifications.”
Keyboard
The PS/2-compatible ergodynamic keyboard is standard equipment for the
system. The keyboard provides a numeric keypad, separate cursor control keys,
12 function keys, and is capable of up to 48 functions. Key status lamps on the
keyboard include Num (Numeric) Lock, Caps (Capital) Lock, and Scroll Lock.
The keyboard’s six-pin connector plugs into the back of the system. Keyboard
specifications are in Section 9, “Specifications.”
Mouse
The system ships with a standard PS/2-compatible mouse. The mouse has a
self-cleaning mechanism that prevents a buildup of dust or lint around the
mouse ball and tracking mechanism.
The six-pin mouse cable connector plugs into the back of the system. Mouse
specifications are given in Section 9, “Specifications.”
AGP
All systems come with the graphics accelerator (AGP) integrated on the system
board. The AGP provides an integrated, advanced MPEG (Motion Picture
Experts Group) 2D/3D graphics and video accelerator for exceptional graphics
and superior quality full-screen, full-motion video.
Included on the system board is a standard VGA output connector for
connecting a VGA-compatible monitor to the AGP component.
Graphics modes are in Section 2, “System Configuration.” Graphics board
specifications are in Section 9, “Specifications.”
