Preface
This manual contains technical information necessary for servicing and repairing the
NEC PowerMateEnterprise NetPC computer from NEC Computer Systems Division,
Packard Bell NEC, Inc. It contains hardware and interface information for users who need
an overview of system design. The manual also includes system setup information,
procedures for installing options, and illustrated parts lists. The manual is written for
NECCSD-trained customer engineers, system analysts, service center personnel, and
dealers.
The manual is organized as follows:
Section 1 — Technical Information provides an overview of computer features and
options, hardware design, interface ports, and internal devices. System specifications are
listed including dimensions, weight, environment, safety compliance, power consumption,
and memory.
Section 2 — Setup and Operation includes unpacking, setup, and operation information.
Procedures are also included for configuring the system with the BIOS Setup utility, setting
passwords, using power management and security features, reinstalling the operating system
or software, and using the BIOS Update utility.
Section 3 — Option Installation provides installation procedures for adding optional
expansion boards, upgrading the hard disk, adding system memory, or upgrading the
processor.
NOTE: Access to the inside of the system is
restricted. The PowerMate NetPC is designed to
be upgraded by qualified, NECCSD-trained
personnnel, such as system administrators,
authorized dealers, NECCSD customer
engineers, and service center technicians.
Section 4 — Maintenance and Troubleshooting includes recommended maintenance
information, along with possible computer problems and their solutions, and the procedures
for battery replacement. NECCSD telephone numbers are provided for obtaining service,
accessing the NECCSD Bulletin Board System, and accessing the NEC FaxFlashSM service.
Section 5 — Repair includes computer disassembly and reassembly procedures. Also
included are an exploded view diagram (Illustrated Parts Breakdown) and a parts lists for
depot-level replaceable parts.

xiv Preface
NOTE: The PowerMate NetPC system is
designed to be repaired by qualified, NECCSD-
trained technicians at the depot level of service.
Appendix A — Connector Pin Assignments provides a list of system, riser, and option
board internal connector pin assignments and a list of external pin assignments for the
keyboard, mouse, serial ports, parallel port, network ports, and video port.
Appendix B —Jumper Settings provides jumper settings for the system board, and for
options that may ship with the computer, including the CD-ROM reader and the fax/modem
board.

Technical Information
SYSTEM OVERVIEW
NEC PowerMateEnterprise NetPC computers are designed to enable central
administration of computer resources in network environments. A highly manageable
platform, the NetPC features network boot capabilities, controlled upgrade paths for system
enhancements, and a “sealed case” that prevents end-user access for changing the system
hardware or software configuration.
NOTE: The PowerMate NetPC system is
designed to be repaired by qualified, NECCSD-
trained technicians at the depot level of service.
PowerMate NetPC systems are available in two basic models with the following features:

Windows®95 operating system, 166-MHz Intel®Pentium®MMXprocessor,
16 MB (minimum) of Synchronous Dynamic Random-Access Memory
(SDRAM), and a 2.0-GB IDE hard disk drive
 Windows NT®4.0 operating system, a 200-MHz Intel Pentium MMX processsor,
32 MB of SDRAM, and a 3.2-GB hard disk drive.
The MMX processor technology boosts audio, video, and 3D graphics performance.
Both PowerMate NetPC models come with an RJ-45 network connector and a video chip
with 2 MB of Synchronous Graphics Random-Access Memory (SGRAM).
Both models also contain audio/video components for multimedia presentations and support
optional memory expansion modules. For further hardware enhancements, both models
contain a PCI expansion slot for adding an optional, half-length, plug and play-compatible
PCI board.
The system features two USB ports, two serial ports, and one parallel port. Ultra DMA,
remote wakeup (“Wake on LAN”), 3D graphics, and power management are supported.
Build choices include hard disk drive and Pentium MMX processor upgrades. System
memory is provided in 16-MB, 32-MB, and (as available) 64-MB and 128-MB DIMM
sticks, in memory configurations ranging from 16 MB to 256 MB.
Figures 1-1 and 1-2 show the front and back features of the PowerMate NetPC system.

1-2 Technical Information
Figure 1-1 PowerMate NetPC Features – Front View
Figure 1-2 PowerMate NetPC Features – Back View

Technical Information 1-3
The NetPC chassis is divided into two sheet-metal halves. This allows the box to be
completely enclosed and “sealed” before plastics are installed on the outside. The top half of
the system contains the hard disk, fan, and power supply. The bottom half contains the
system board and riser card.
Figure 1-3 Top and Bottom Chassis Assemblies
The basic hardware features inside the PowerMate NetPC are listed below:
 Intel CN430TX system board
 Intel Pentium 166-MHz MMX processor
Intel Pentium 200-MHz MMX processor
 RJ-45 LAN connector (on riser card) for connection to an Ethernet network
 Two 168-pin DIMM sockets; system memory from 16 MB using 16-MB, 32-MB,
