1-2 System Overview
This section provides an overview of the NEC PowerMate8100 Series desktop
configuration. The section highlights system hardware features, computer front,
back, and inside features, and system security features. It also includes brief
descriptions of the major components comprising the system.
Configurations
NEC PowerMate 8100 Series computers are built-to-order systems for
commercial offices. The systems feature an Intel Celeron™, PentiumII, or
Pentium III processor, three dual inline memory module (DIMM) sockets,
synchronous dynamic random access memory (SDRAM), and a plug and play
input/output (I/O) controller.
The system also features two universal serial bus (USB) ports, two serial ports, a
parallel port, and an infrared port. Ultra direct memory access (DMA), remote
wakeup (“Wake-On LAN”), accelerated graphics port (AGP), and power
management are supported.
Build choices include intelligent device electronics (IDE) hard drives ranging
from 3.2 gigabyte (GB) to 14.4 GB, and an ultra wide SCSI 4.55-GB or 9.1-GB
hard drive. System memory is provided in 32-megabyte (MB), 64-MB, 128-MB,
and 256-MB DIMM modules. Memory configurations range from 32 MB to 384
MB. Additional build choices include fax/modem, sound, video, CD-ROM
drive, a DVD-ROM drive, a Zip drive, or a tape backup unit.
The NLX system design leaves the system board free of internal cabling and
allows easy system board removal and replacement with a simple chassis latch.
The following figure shows the components shipped with PowerMate 8100
Series desktop systems (the monitor and speakers are optional).
