HARD DISK DRIVE

All systems ship with one internal 3 1/2-inch hard disk drive (1-inch high, thin-height)
installed in the internal drive slot along the right side of the computer, at the rear of the
system. Drives are available in a 1.0-GB EIDE model, 2.1-GB, 3.2-GB, 4.3-GB, and
6.4-GB IDE models, and a 4.5-GB SCSI model.
All systems come with a two-connector IDE cable connected to the primary PCI/IDE
channel, and a three-connector IDE cable connected to the secondary PCI/IDE channel. In
systems with an IDE hard disk drive, the two-connector cable connects to the IDE hard
disk drive and the primary connector on the riser board. The riser board has two PCI/IDE
interface connectors (primary and secondary) for connecting IDE storage devices. Each
connector supports up to two IDE devices.
An optional second IDE hard disk drive can be added to the secondary PCI/IDE channel. If
the second hard disk drive is installed, it connects to the middle connector on the IDE cable.
In systems with a SCSI hard disk drive, a four-connector SCSI cable connects the drive to
the internal SCSI connector on the SCSI adapter board. Up to three internal SCSI devices
can be added to the cable.
Use the "Storage Device Installation" procedures in Section 3 when installing optional
devices. Connector locations are given in Appendix A. Jumper settings are given in
Appendix B. Hard disk drive specifications are given in Table 1-20 through Table 1-26.

POWER SUPPLY

The power supply is mounted inside the system unit. It supplies power to the system board,
option boards, diskette drives, hard disks, CD-ROM reader, keyboard, mouse, and other
internal options. A fan inside the power supply provides system ventilation. The power
supply provides 200 watts, and is NLX-compatible. Power supply specifications are given in
Table 1-35. Connector locations are given in Appendix A.

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 rear of the system. Keyboard specifications are given in Table 1-17.

MOUSE

A Microsoft IntelliMouse is standard equipment for the system. This PS/2-compatible
mouse has two buttons and a cursor control button. 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 rear of the system. Mouse
specifications are given in Table 1-16.
