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.
PowerMate NetPC systems are available in two basic models with the following features:
T
®
Windows
16 MB (minimum) of Synchronous Dynamic Random-Access Memory
(SDRAM), and a 2.0-GB IDE hard disk drive
T
Windows NT
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.
NOTE: The PowerMate NetPC system is
designed to be repaired by qualified, NECCSD-
trained technicians at the depot level of service.
