1-2 System Overview
This section provides an overview of the NEC PowerMate5100 Series
mini-desktop computer system configurations. The section highlights system
hardware features, computer front, back, and inside features, and system
security features. Also included are brief descriptions of the major components
comprising the system.
Configurations
NEC PowerMate 5100 Series computers are built-to-order systems for
commercial offices. The systems feature an IntelCeleron™ or PentiumII
processor, a built-in Accelerated Graphics Port (AGP) controller, two 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,
and a parallel port. Ultra direct memory access (DMA), built-in LAN circuitry
with remote wakeup (“Wake-On LAN”), and power management are supported.
Build choices include intelligent device electronics (IDE) hard drives ranging
from 2.1 gigabyte (GB) to 8.4 GB. System memory configurations range from a
minimum of 32 megabyte (MB) to a maximum of 256 MB using 32-MB and, as
available, 64-MB and 128-MB DIMM modules.
Additional build choices include fax/modem, network, video, and peripheral
devices such as CD-ROM drives.
The NLX chassis 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 the PowerMate 5100
Series system (the monitor and speakers are optional).

paragraphs. Also included are descriptions of the system’s security features.

1-4 System Overview
Front Features
The following figures identify the components, lamps, and controls on the front
of the system. Brief descriptions of the components follow the figures.

C– Diskette Drive (not installed in all systems)
System Controls and Lamps
A– Power Button B– Power Lamp C– Suspend Button D– Reset Button E– Disk Lamp
System controls allow the selection of specific system operations. Lamps
visually alert the user to the status of system operation. The system has the
following devices, controls, and lamps on the front of the system (see the
preceding figures for device, control, and lamp locations).

Diskette drive (not installed in all systems) — copy data files to and from
a diskette or as a bootable drive for loading and starting programs from a
diskette.

CD-ROM drive (not installed in all systems) — load and start programs
from a compact disc (CD) and to play audio CDs.

System Overview 1-5
 Suspend button — suspends system operation for saving power in
systems with Windows 95 or Windows 98 installed. An amber power
lamp lights when in suspend (power-saving) mode. Pressing any key or
moving the mouse resumes system operation. The Suspend button does
not function in systems with Windows NT 4.0 installed.
 Disk lamp — when lit, indicates that the hard drive is active. A lit lamp
indicates that the hard drive is reading or writing data.
 Power lamp — indicates if system power is on or off or in suspend mode.
A steady green lamp indicates power is on to all components. An amber
lamp indicates that the system is in suspend mode with full power
reduction.
 Reset button — restarts the computer after it is powered on. Used to reset
the computer if it is not operating properly.
 Power button — turns system power on or off.
Back Features
The back of the computer contains external connectors, a power socket, and
expansion board slots. The following figures identify the connectors on the back
of the system. Brief descriptions of each connector follow the figures.
