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:

designed to be repaired by qualified, NECCSDtrained 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

The PowerMate NetPC system is



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.

Processor and Secondary Cache

The system uses an Intel Pentium processor with an internal clock speed of 166 MHz, or 200 MHz. These processors use Intel MMX technology.

The processor is an advanced pipelined 32-bit addressing, 64-bit data processor designed to optimize multitasking operating systems. The 64-bit registers and data paths support 64-bit addresses and data types.

Page 24

1-8 Technical Information

The MMX processor has 32 KB of built-in cache memory (16 KB instruction and 16 KB data). To use the Pentium processor’s power, the system features an optimized 64-bit memory interface and 256 KB of secondary write-back cache located on the system board.

The processor is compatible with 8-, 16-, and 32-bit software written for the Intel386™, Intel486™, Pentium, and Pentium Pro processors. The Pentium processor is mounted into a socket-7 zero insertion force (ZIF) socket. Systems with the 166-MHz processor can be upgraded to 200-MHz. The socket provides an easy upgrade path.

System BIOS

The system BIOS is from Intel, based on Phoenix Technologies Limited (PTL) BIOS ‘95. This ISA- and PCI-compatible BIOS is contained in a flash memory device on the system board. The BIOS provides the Power-On Self-Test (POST), the system Setup program, a PCI and IDE auto-configuration utility, and BIOS recovery code.

The system BIOS is always shadowed. Shadowing allows any BIOS routine to be executed from fast 32-bit DRAM on the system board, instead of from the slower 8-bit flash device.

NEC’s Flash ROM allows fast, economical BIOS upgrades. The Flash ROM is a reprogrammable EPROM containing both the system and video BIOS. Using the Flash ROM to change the ROM BIOS provides the following advantages:

the BIOS upgrade is performed quickly and easily



the expense of replacing ROM BIOS chips is eliminated, so system maintenance costs are reduced



there is less chance of inadvertently damaging the system board than when physically replacing ROMs



new technology can be incorporated while maintaining corporate standards



network administrators can exercise company-wide control of BIOS revisions.

Page 25

Technical Information 1-9

The BIOS programs execute the Power-On Self-Test, initialize processor controllers, and interact with the display, diskette drives, hard disk drives, communication devices, and peripherals. The system BIOS also contains the Setup utility. The POST copies the ROM BIOS into RAM (shadowing) for maximum performance.

The Flash ROM allows the system and video BIOS to be upgraded with the BIOS Update utility, without having to physically remove the ROM (see Section 2 for further information on the BIOS Update utility). The Flash ROM supports the reprogramming of the system BIOS and the video BIOS.

The system memory map is shown in Table 1-3.

System Memory

The system comes with between 16 MB and 256 MB of SDRAM installed in dual in-line memory module DIMM sockets on the system board.

The memory configuration consists of two sockets. The DIMM memory sockets accept 168-pin, 64-bit (non-parity) 8-, 16-, 32-, 64-, and 128-MB DIMMs. Table 1-5 lists the supported DIMMs.

Page 28

1-12 Technical Information

Memory upgrades are easy with DIMMs. Advantages of using DIMMs are listed below:



DIMMs do not need to be installed in pairs on the system board. DIMMs of different memory types and sizes can be installed on the same board.



No switches or jumpers need to be set if the memory is changed.



The system BIOS automatically detects the DIMMs.

See “Checking the Memory in the System” in Section 3 for the valid DIMM configurations.

Hardware Monitor

The National Semiconductor Heceta LM78 chip provides economical instrumentation capabilities (NEC MagicEye™ Technology) for reduced cost of PC ownership when the system is used with the LANDesk® Client Manager. This single-chip ASIC features:



integrated ambient temperature sensor



power supply voltage monitoring to detect excessively high or low voltage levels



registers for storing POST hardware test results and error codes



remote reset capabilities from a remote peer or server through LANDesk Client Manager v.3.0

When ranges for temperature, fan speed, or voltage are exceeded, an interrupt is activated. The hardware monitor component connects to the ISA bus as a 8-bit I/O mapped device.

Interrupt Controller

The interrupt controller operates as an interrupt manager for the entire system environment. The controller:



accepts requests from peripherals



issues interrupt requests to the processor



resolves interrupt priorities



provides vectors for the processor to determine which interrupt routine to execute.

The interrupt controller has priority assignment modes that can be reconfigured at any time during system operations.

The interrupt levels are described in Table 1-6. Interrupt level assignments 0 through 15 are in order of decreasing priority. See Section 2 for information on using the Setup utility to change the interrupts.

Technical Information 1-15

Plug and Play

The system comes with a Plug and Play BIOS in support of Plug and Play technology. Plug and Play simplifies setup procedures for installing Plug and Play expansion boards. With Plug and Play, adding a Plug and Play expansion board is done by turning off the system, installing the board, and turning on the system. There are no jumpers to set and no system resource conflicts to resolve. Plug and Play automatically configures the board. (Some Plug

and Play devices may need to be jumpered if used in a system running the Windows NT



operating system.)

Chassis

The NetPC chassis is divided into two sheet-metal halves. The system has one 3.5-inch drive slot for a hard drive and one add-in card slot, which accepts a half-length PCI card. The dimensions of the chassis are included in Table 1-16.

Power connections to the system board are carried through the riser card, which also contains the half-length PCI card slot.

PCI Local Bus

The 32-bit PCI bus is the primary I/O bus for the system. The PCI bus is a highly-integrated I/O interface that offers the highest performance local bus available for the Pentium processor. The bus supports burst modes that send large chunks of data across the bus, allowing fast displays of high-resolution images.

The PCI bus operates at half the Pentium processor’s bus speed. The PCI bus supports memory transfer rates of up to 105 MB per second for reads and up to 120 MB per second for writes, depending on processor configuration.

The high-bandwidth PCI bus eliminates the data bottleneck found in traditional systems, maintains maximum performance at high clock speeds, and provides a clear upgrade path to future technologies.

PCI expansion slot connector pin assignments are provided in Appendix A.

Page 32

1-16 Technical Information

PCI/IDE Ports

The system board supports one high-performance PCI/IDE port (the primary channel for a master/slave configuration), though the port is actually located on the riser card. The port supports one or two devices in a master/slave setting configurable in BIOS Setup. The primary PCI/IDE port has an enhanced IDE interface that supports PIO Mode 4 devices with 16 MB per second 32-bit wide data transfers on the high-performance PCI local bus. The channel supports Ultra DMA/33. The installed hard disk drive is connected to the primary PCI/IDE port with a two-connector cable. A second Ultra DMA/33 device can be logically added to the primary PCI/IDE channel, but in such a case, neither device should run in Ultra DMA/33 mode because the length of the three-connector cable required for this configuration would cause signal degradation.

NOTE:

Physically, the chassis only has room for

one hard disk drive.

Parallel Interface

The system has a 25-pin bi-directional parallel port on the system board. Port specifications conform to the IBM-PC standards. The port supports Enhanced Capabilities Port (ECP) and Enhanced Parallel Port (EPP) modes for devices that require ECP or EPP protocols. The protocols allow high-speed bi-directional transfer over a parallel port and increase parallel port functionality by supporting more devices.

The BIOS has automatic ISA printer port sensing that works with most devices. If the BIOS detects an ISA printer port mapped to the same address, the built-in printer port is disabled. (Verify in the BIOS Setup that printer ports mapped to the same address are enabled or disabled appropriately.) The BIOS also sets the first parallel interface port it finds as LPT1 and the second port it finds as LPT2. The interrupt is set at IRQ7 via the Setup utility. Software-selectable base addresses are 3BCh, 378h, and 278h.

Sets of I/O addresses and interrupts for the parallel port are given in Table 1-8. This is a list of all possible configurations; the parallel port uses only one set.

Serial Interface

The system has two 16C550 UART compatible serial ports (COM1 and COM2) integrated on the I/O controller. The serial ports support the standard RS-232C interface. The buffered high-speed serial ports support transfer rates up to 115.2 KB. These ports allow the installation of high-speed serial devices for faster data transfer rates.

Sets of I/O addresses and interrupt levels for the two channels are given in Table 1-9 and Table 1-10. (Note that COM2 is disabled by default.) The interrupt levels are selectable via the Setup utility and include IRQ3 and IRQ4. Software selectable base addresses are 3F8h, 2F8h, 3E8h, and 2E8h. If serial ports are reconfigured to share an interrupt, verify that the software and hardware added by users can share interrupts without problems.

Serial interface signals are output through the system board 9-pin, D-subconnectors. The connectors are located at the rear of the system unit. Pin locations for the serial interface connector are shown in Appendix A.

USB Interface

The Universal Serial Bus (USB) ports allow new Plug and Play serial devices to be added without having to open the system. The devices may be plugged into a USB port. The USB determines system resources for each peripheral and assigns them without user intervention. With a hub and the proper cabling, up to 127 devices can be daisy chained to a single computer. Boot support for a USB keyboard is present so the system can be booted with a USB keyboard instead of a standard keyboard.

Video Interface

The system board features the S3 Trio 64 ViRGE/GX 3D accelerator chip with 2 MB of video SGRAM soldered on the system board.

The video and graphics controller accelerates color space conversion and video upscaling to deliver exceptional graphics and high quality MPEG and video playback and true multimedia functionality. MPEG is a compression/decompression standard developed by a professional video group called the Motion Picture Experts Group. MPEG produces fullscreen, 30-frames-per-second, broadcast-quality digital video.

The graphics accelerator chip provides:

Integrated Audio

To support the increasing number of multimedia applications, a Yamaha OPL3-SA3 chip is integrated on the system board. The chip provides 16-bit stereo, Sound Blaster Pro-

compatible audio. System boards with audio provide a line out jack and microphone jack. The sound system provides all the digital and analog mixing functions required for playing

and recording audio on personal computers. Features include stereo analog-to-digital and digital-to-analog converters, analog mixing, anti-aliasing and reconstruction filters, line and microphone level inputs, digital audio compression, and full digital control of all mixer and volume control functions.

The sound system is standard and features the following:

Page 37

Technical Information 1-21

The Yamaha OPL3-SA3 includes a full Plug and Play interface. Each logical device is configured into the host environment using the Plug and Play configuration methodologies. The audio subsystem requires two DMA channels and one interrupt.

DISKETTE DRIVE SUPPORT

A diskette drive is not included in the system. However, the riser card contains a diskette drive connector and controller. A diskette drive with its own power source can be connected by a ribbon cable to the diskette drive connector on the riser card. You must enable the diskette drive controller in BIOS Setup to use a diskette drive in the NetPC system (see “Setup Utility” in Section 2).

HARD DISK DRIVE

All systems ship with one internal 3 1/2-inch hard disk drive (1-inch high, thin-height) installed in the internal drive slot in the top half of the chassis. Drives are available in

2.0-GB and 3.2-GB Western Digital models. A two-connector hard disk drive IDE cable connects to the hard disk and the primary

connector on the riser card. The riser card has one IDE/PCI interface connector (primary only) for connecting IDE storage devices such as hard disk drives. Logically, the connector supports up to two IDE devices. Physically, there is room for one hard disk in the chassis.

An optional second hard disk drive can be added to the primary channel if the cable is replaced with a three-connector IDE cable. If an additional hard disk drive is added to the primary IDE channel, configure both devices as non-Ultra DMA.

Use the “Storage Device Installation” procedures in Section 3 when replacing the hard disk. Connector locations are given in Appendix A. Jumper settings are given in Appendix B. Hard disk drive specifications are given in Table 1-17 and Table 1-18.

POWER SUPPLY

The power supply is mounted inside the top chassis. It supplies power to the system board, option board, hard disk, keyboard, and mouse. A fan inside the chassis provides system ventilation. The power supply provides 51 watts (rated). Connector locations are given in Appendix A.

The power supply connector differs from the standard NLX and ATX power supply connectors. Pin 18 of the PowerMate NetPC power supply is used for thermal fan speed control and not for -5V.

WARNING:

ATX power supply to operate the NetPC system, as this will cause the fan circuit to fail.

Do not use a standard NLX or

Page 38

1-22 Technical Information

The power supply supports remote power on/off. This means that the system board and riser card can turn off the system power through software control. Pin 14 of the power supply connector lets the system board recognize a power supply that supports this “softoff” feature.

To enable soft-off control in software, power management (PM) must be enabled in the operating system. When the system BIOS receives the correct PM command from the operating system, the BIOS turns off power to the computer. For example, in the Windows 95 Start menu, the user selects Shutdown to turn off the power.

Depending on how “Restore On AC/Power Loss” is configured in the Setup utility (see “Boot Menu” in Section 2), if power to the computer is interrupted by a power outage or a disconnected power cord, when power resumes, the computer returns to the state it was in before the power interruption. The default CMOS setting for a power loss is “Last State.”

RISER CARD

The riser card serves as an interface between the system board and the network and between the system board and any installed PCI expansion board. The riser card contains an RJ-45-compatible LAN connector for connecting the system to an Ethernet network. The card also contains a PCI expansion slot for installing a half-length PCI expansion board. The riser card connects to the system board through a 170-pin edge connector and also cable-connects to the power supply to provide DC power to the NetPC system components. The riser card contains one primary IDE connector for the system’s hard disk and also contains a diskette drive connector. For more information on riser card features, see Table 1-21. Connector pin assignments for the riser card are provided in Appendix B.

MOUSE

A Microsoft IntelliMouse is standard equipment for the system. This PS/2-compatible mouse has two buttons and a cursor control button. The mouse has a self-cleaning mechanism that prevents a buildup of dust or lint around the mouse ball and tracking mechanism. The six-pin mouse cable connector plugs into the rear of the system. Mouse specifications are given in Table 1-14.

This completes the system setup procedures. For information about using the Setup Utility to set system parameters, see the following subsection.

SETUP UTILITY

The Setup utility program is used to configure the main components of the computer.

NOTE: The system ships from the factory with the correct system parameters for the configuration. Unless you add optional hardware, you do not need to run Setup to operate the system. However, you might wish to run the Setup utility to set features that customize the system, such as security features.

System configuration information is stored in nonvolatile memory. A nonvolatile memory device retains its data when system power is turned off. Nonvolatile memory in the system is stored in a complementary metal-oxide semiconductor (CMOS) chip backed up by a battery on the system board. The battery supplies continuous power to CMOS memory and maintains configuration information when system power is off.

NOTE: NECCSD recommends that you print out or write down the current Setup parameters and store the information in a safe place. This allows you to restore the system to the current parameters if you ever need to have the battery replaced.

Page 57

Technical Information 2-11

Page 62

2-16 Technical Information

Advanced Menu

Selecting “Advanced” from the Main menu displays a menu with the following options.

PnP O/S

The PnP field indicates if the computer’s operating system is configured to use Plug and Play devices. Choose “Yes” if you are using a system that has Plug and Play. The default is “Yes” for Windows 95 systems. For systems without Plug and Play (such as Windows NT

4.0), this field is set to “No.”

Reset Configuration Data

Use this setting to clear CMOS (by selecting “Yes” and rebooting) if the system parameters get corrupted. The default is “No.”

Memory Cache

Memory cache saves time for the CPU by holding data most recently accessed in regular memory (dynamic RAM or DRAM) in a special storage area of static RAM (SRAM), which is faster. Before accessing regular memory, the CPU first accesses the cache. If it does not find the data it is looking for, it accesses the regular memory.

The default for the Memory Cache is “Enabled.” This field controls both the primary and secondary caches. Setting the Memory Cache to “Disabled” will hurt performance, but might be required when running programs that utilize software-timing loops and need to be slowed down to execute properly.

Memory Banks 0 and 1

The two Memory Bank fields are read only. They display the total amount of memory in each DIMM bank.

Resource Configuration



Memory Reservation Use this field to reserve specified blocks of upper memory for use by other ISA devices. Select “Reserved” to choose a memory block. The default for each block is “Available.”

LANDESK CLIENT MANAGER

LANDesk Client Manager (LDCM) is a software program available on the NEC Select Install CD. LDCM uses the Desktop Management Interface (DMI) standard to manage components (network interface cards, memory, software applications) within a Client (local) or remote (workstation) PC system. It provides features for managing the resources of a local PC and can be used by system administrators to manage groups of computer systems.

See “NEC Select Install CD” for instructions on installing LANDesk Client Manager on the NetPC hard disk.

With Client Manager you can perform the following tasks:



review system inventory of workstation hardware and software components



view DMI-compliant component information



troubleshoot



There are two main components of Client Manager: PC Health Indicator and Inventory.

PC Health Indicator

PC health indicator consists of three parts:

Workstation management



PC Health meter



PC Health description.

Workstation Management

Client Manager sets up a connection to all the workstations running on the network to allow the administrator to monitor the functions of each workstation.

The monitoring is in real time so that if an unhealthy workstation is fixed, you can refresh the screen to view the new correct PC health. You can also set the monitor to report only unhealthy workstations.

PC Health Meter

The PC Health meter is a traffic signal that provides a visual indicator of workstation health.



A red light indicates that a critical system event has occurred. You are required to fix the problem immediately.



A yellow light or noncritical system event requires that you monitor the situation. It may be a problem that could get worse and become a critical event.



A green light indicates everything is working fine with the system.

PC Health Description

The description of PC health is determined by monitoring various system components for threshold levels. Some of the components that are monitored include:



drive space



prediction of hard drive failure with automatic data backup (see “NEC Auto Backup Utility for further information)



DMI

The Desktop Management Interface (DMI) is the industry-standard used to manage system components on the computer. The PowerMate NetPC uses this standard along with LANDesk Client Manager to ensure interoperability among different vendor’s computers. Examples of system components are network interface cards and software applications. System components provide a Management Information Format (MIF) file to be DMIcompliant. The information file describes component attributes that can be managed.

Client Manager can be used to “get” attribute information on system components. It can also be used to “set” attribute values in real time.

More information on DMI is available on the World Wide Web at

http://www.dmtf.org

Monitoring Capabilities

The PowerMate NetPC computer has a chip (NEC MagicEye™ technology) mounted on the system board that supports many new and advanced real-time monitoring capabilities used by DMI. This chip provides the following features:



an integrated temperature sensor with configurable interrupt generation based on upper and lower temperature limits



a power supply monitor with configurable interrupt generation based on upper and lower voltage limits

chassis intrusion detection with interrupt generation capabilities.



To take advantage of these features, DMI has expanded its interface in the following areas:



Interrupts can be enabled or disabled.



High and low limits can be set and are displayed for temperature and power supply voltages.



Current readings are displayed for temperature, power supply voltages, and chassis state.



Interrupts can be detected when “out of range” conditions occur. User prompts are displayed to alert the user to a potentially harmful condition.

NEC AUTO BACKUP UTILITY

The NEC Auto Backup utility is a data management and backup program that operates in conjunction with LANDesk’s DMI and the Self-Monitoring Analysis and Reporting Technology (S.M.A.R.T) Hard Drive instrumentation. If the S.M.A.R.T. drive identifies a potential problem, the NEC Auto Backup utility automatically invokes the Cheyenne Backup program and backs up the entire file system to a user-selected backup device, such as a Zip drive, network drive, or tape.

NEC Auto Backup can also do regularly-scheduled backups and scan files for viruses during a backup operation.

NOTE: For the NEC Auto Backup utility to work, Cheyenne Backup must be preconfigured. See the NEC Auto Backup utility “Read Me” file for information about Cheyenne Backup.

The NEC Auto Backup utility is available on the NEC Select Install CD. See “NEC Select Install CD” for instructions on installing the NEC Auto Backup utility on the NetPC hard disk.

NEC SELECT INSTALL CD

The system comes with an NEC Select Install compact disc (CD). This disc contains all the system software files. Use the NEC Select Install CD to download the operating system and application software from a hardware/software service platform, such as LANDesk Configuration Manager (LCM). Should a problem occur that causes data loss or corruption, you can restore the system files using the NEC Select Install CD.

The Select Install CD installs all or part of the computer’s software in two phases:



operating system (OS) restore program



selective application restore program.

The OS restore phase allows you to install Windows 95 or Windows NT from the LCM CD-ROM reader. If you need to do a full restore, start with phase one.

Phase two, the Selective Application Restore program, takes place while the OS is running and lets you choose the application software you want to install. Use phase two for installing selected applications from the LCM CD-ROM reader at any time.

Both the OS and application phases use easy-to-understand dialog boxes and screen messages so you can smoothly proceed through the installation process.

The following sections explain how to use the NEC Select Install CD with LCM.
