System Overview 1-11
Diskette Drive
A single diskette drive is supported in the system (the BIOS does not support a
second diskette drive). The installed 1.44-MB 3 1/2-inch diskette drive is
connected by a single ribbon cable with three connectors. The diskette drive
cable plugs directly into the riser board. There are no switches or jumpers that
need to be set and the diskette drive is terminated.
Connector locations for the diskette drive on the riser board are given in
Section 5, “Riser Board.” Section 6, “Illustrated Parts Breakdown,” lists the
NEC CSD part for the diskette drive. Diskette drive specifications are given in
Section 10, “Specifications.”
Hard Drive
All systems ship with one internal 3 1/2-inch hard drive (1-inch high, thin-
height). The drive is installed in the internal drive bay in the right rear of the
system. Drives are available in 3.2-GB, 4.3-GB, 6.4-GB, 8.4-GB, 12.9-GB, and
14.4-GB IDE Ultra DMA models. Also available are 4.55-GB and 9.1-GB SCSI
drives.
The riser board has two IDE/PCI interface connectors (primary and secondary)
for connecting IDE storage devices. In systems with an IDE hard drive, a three-
connector hard drive IDE cable connects to the IDE hard drive and the primary
connector on the riser board. Each connector supports up to two IDE devices.
An optional second IDE hard drive can be added to the primary channel. If the
second hard drive is installed, it connects to the middle connector on the IDE
cable.
In systems with a SCSI hard drive, a four-connector SCSI cable connects the
drive to the internal SCSI connector on the SCSI adapter board. A total of three
internal SCSI devices can be added to the cable.
Hard drive jumper settings are given in Section 2, “System Configuration.”
Connector locations for the IDE hard drive connectors on the riser board are
given in Section 5, “Riser Board.” Section 6, “Illustrated Parts Breakdown”
lists the NEC CSD parts for the hard drives. Hard drive specifications are given
in Section 10, “Specifications.”
Power Supply
The power supply is mounted inside the system unit. It supplies power to the
system board, riser board, option boards, diskette drive, hard drives, CD-ROM
drive, DVD-ROM drive, 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.
