Technical Information 1-17
Infrared Interface
The I/O controller incorporates an infrared interface that provides two-way wireless
communication through the IrDA window (port) on the front of the system. The interface
uses infrared as the transmission medium instead of a traditional serial cable.
The IrDA port permits transfer of files to or from portable devices such as laptops and
personal digital assistant (PDA) products using the pre-installed LapLink applications
software or other software supporting IrDA data transfer. The port supports data transfers
at 115 Kbps from a distance of 1 meter (3 feet 3 inches).
The IrDA port uses the system’s COM2 serial port to transfer data. The port shares
registers and function logic with COM2.
POWER SUPPLY
The power supply is mounted inside the system unit. It supplies power to the system board,
option boards, diskette drives, hard disks, keyboard, and mouse. A fan inside the power
supply provides system ventilation. The power supply provides 200 watts. Connector
locations are in Appendix A.
DISKETTE DRIVE
Up to two diskette drives are supported in the desktop and minitower systems. The installed
3 1/2-inch diskette drive is connected by a single ribbon cable with two drive connectors.
The diskette drive cable plugs directly into the system board. Typically both diskette drives
are terminated. Connector locations are given in Appendix A.
HARD DISK DRIVE
Up to four IDE hard drives are supported in the desktop and minitower systems. The
system board has two IDE/PCI interface connectors (primary and secondary) for connecting
various storage devices such as hard disk drives. Each connector supports up to two IDE
devices.
Desktop hard disk systems ship with one internal 3 1/2-inch hard disk drive (1-inch high,
thin-height) installed behind the front panel. The drive cable plugs into the primary (fast)
connector on the system board.
Minitower hard disk systems ship with one internal 3 1/2-inch hard disk (1-inch high, thin-
height) installed behind the front panel, at the bottom of the chassis. The three-connector
drive cable plugs into the primary (fast) connector on the system board. An optional second
hard drive can be connected to the cable and installed at the bottom of the minitower
chassis (see Section 3). Adding a third hard drive requires an optional two-drive connector
cable (NEC part number 158-050383-004). The optional cable plugs into the secondary
connector on the system board. If adding a fourth hard drive (in a 5 1/4-inch accessible
slot), it connects to the unused connector on the optional cable.
