Hardware Preparation and Installation

Hardware Installation

The following sections discuss the placement of adapter boards on the VP22 motherboard, the instal lation of the complete VP22 assembly int o an ATX chassis, and the system considerations relevant to the installation. Before installing the VP22 board, ensure that the header jumper is configured as desired.

Installation Preliminaries

This section applies to all hardware installations you may perform on VP22 motherboards.

ESD

Motorola strongly recommends that you use an a ntistatic wrist stra p and a conductive foam pad when installing or upgrading a system. Electronic components, such as d isk dr ives, c omputer boards , and memor y modules , can be extremely sensitive to electrostatic discharge (ESD). After removing the component from its protective wrapper or from the system, place the componen t flat on a grounded, static -free surface (an d, in the case of a board, component side up). Do not slide the component over any surface.

If an ESD station is not available, you can avoid damage resulting from ESD by wearing an antistatic wrist strap (available at electronics stores) that is attached to an active electrical ground. Note that a system chassis may not be grounded if it is unplugged.

Warnin g

To prevent serious injury or death from dangerous voltages, before connecting peripheral s, disconnect the power cord from the power source. Only qualified, experienced electronics personnel should access the interior of a system.

Functional Descr iption

VP22 Processor

The VP22 motherboard sup ports a singl e Intel PGA370 s ocket Pentium III or Celeron processor. The Pentium III has a FSB speed of 100/133 MHz and the Celeron has a FSB speed of 66 MHz. The 815E chipset keeps the FSB operation at 66/100/133 MHz (auto-selected).

System Memory

The VP22 motherboard supports synchronous DRAM memory and accepts the standard (unbuffered) SDRAM DIMM memory. SDRAM speed, type and size is determined by the BIOS reading the DIMM presence detect bits on the SMBus (System Management Bus). The SDRAM timing register, which provides the DRAM speed contr ol for th e entire array, must be programmed to use the timings of the slowest DRAMs installed.

This motherboard supports up to 512MB of SDRAM memory with three 168-pin DIMM sockets. It suppo rts 3.3 V single- or double-si ded DIMMs and the individual SDRAMs on the DIMMs must be (x8) or (x16) parts; (x4) parts are not supported. The DIMM sockets can be populated in any order. SDRAM operation at 133MHz and 100MHz is supported.

L2 Cache

The Pentium III has an on-die 256KB L2 Advanced Transfer Cache (ATC). The on-die cache has a 256-bit data bus from the processor core. The Celeron has 128KB L2 ATC.

Universal Serial Bus

Three Universal Serial Bus (USB) ports are supported on the VP22 motherboard; two USB ports are located at the rear panel and one 5-pin header is onboard for internal use. USB allows for the easy addition of peripherals such as a mouse, keyboard, speakers, etc. Transfer rates up to 12Mb/s are supported. The 12Mb/s high-speed connection requires shielded cables.

2-4 Computer Group Literature Center Web Site

Page 37

PCI Expansion Slots

The VP22 provides the stan dard 0.5 A a t 5 V to t he peri phera ls. Power on each USB port is prot ected by a single pol yswitch fuse (size 6 V/ 1.1 A, this current rating allows for inrush currents). Additional ports can be added through the use of an external USB hub.

PCI Expansion Slots

The VP22 supports four 32-bit, 33 MHz PCI expansion slots. These are +5 V signaling slots that accommodate either +5 V or universal PCI boards.

Ethernet Interface

The VP22 provides a 10/100BaseTX Ethernet transceiver interface using an Intel 82562EM integrated Ethernet device. The Ethernet interface is accessed via an industry-standard, rear-panel-mounted RJ-45 connector.

The 82562EM chip is assigned an Ethernet Station Address. The address is unique for each board (assembly) and is displayed on a label affixed to the board. In addition, the Ethernet address is stored in the configuration ROM interfaced to the 82562EM Ethernet device.

The Ethernet interface on the rear panel of the VP22 motherboard is accompanied by two LED indi cators. Table 2-2 details the functionality of each indicator.

Functional Descr iption

Super I/O Device

The VP22 uses the Super I/O (SIO) device to provide two asynchronous serial ports, a peripheral parallel port, a PS/2 floppy port, PS/2 keyboard/mouse ports and an IrDA header.

Asynchronous Serial Ports

Two 16550-compatible asynchronous serial ports are supported on the VP22 motherboard. The EIA-232 drivers and receivers reside onboard. COM1 is routed to an industry-standard DB-9 connector accessible from the rear panel an d COM2 is routed t o an optional 10-pin header . Bo th ports are configured as DTE. Maximum data rate on any port is 115.2K baud.

Firmware initializes the two serial ports as COM1 and COM2 with ISA I/O base addresses of 3F8h and 2F8h respectively. This default configuration also assigns COM1 to IRQ4 and COM2 to IRQ3.

Peripheral Parallel Port

All parallel I/ O interf ace signa ls are r outed to an indust ry-sta ndard DB-25 connector, accessible from the rear panel. This port supports the full IEEE-1284 capability, which provides the basic printer interface. Firmware initializes the parallel port as LPT1 with ISA I/O base address of 378h. This default configuration also assigns the parallel port to IRQ7.

PS/2 Floppy Port

The floppy port is confi gured for PS/2 compatibility a nd supports bot h the legacy 34-pin header and the compact f loppy disk drive (FDD) co nnector. Up to two floppy drives are supported.

Keyboard and Mouse Ports

Two 6-pin circular DIN connectors are located on the rear panel of the VP22 motherboard for the keyboard and mouse connections. The power provided to the keyboard and mouse is protected by a polyswitch rated at

1.1 A.

2-6 Computer Group Literature Center Web Site

Page 39

Interval Timers

The voltage regulat or has thr ee count ers t hat are typica ll y progra mmed to provide the following functions:

❏ Counter 0 is associated with IRQ0 and can be used for system

timing functions, such as timer interrupt for a time-of-day.

❏ Counter 1 is used to g enerate a re fresh request signal fo r ISA

memory every 15.6 us.

❏ Counter 2 is typically programmed to provide a speaker tone.

Real-Time Clock and NVRAM

The real-time clock provides a century calendar, as well as a time-of-day function. In addition , 256 bytes of battery-backed RAM is available for use by the BIOS. A separate 3 V coin cell battery provides battery-backup.

BIOS

The VP22 supports the Intel 82802BA Firmware Hub (FWH). A boot block device allows recovery of the BIOS in the event of a catastrophic failure (power fail during BIOS update). Flash write protection is implemented under so ftware control and this bit must be set to 1 before any write is allow ed to the BIOS Flash. For mor e information o n the VP22

motherboard’ s BI OS, refer to the VP22 mi cr oA TX Motherboar d BIOS and

Programmer’s Reference Guide, listed in Append ix C, Rela te d

Documentation.

Audio Interface

The VP22 provides a two channel, multimedia audio device capable of

Audio Codec ’97 (AC ’97). Three connectors are available on the rear panel: MIC IN, LINE IN and LINE OUT.

http://www.motorola.com/computer/literature 2-7

Page 40

Functional Descr iption

Video Interface

Standard SVGA analog output i s available on the r ear I/O panel. The video function is provided via the Intel 8 2815 Graphics Memory Cont roller Hub (GMCH). The BIOS must have a selection in the CMOS setup to disable the onboard video to allow the user t o use a PCI video as the primary video controller. The BIOS must also have a selection in the CMOS setup to disable the onboard video to allow the user to reclaim the memory for applications without having to add another video card.

Reset

The VP22 has a circuit that monitors system power and provides the PWROK signal to the 82801BA I/O Controller Hub2 (ICH2). This circu it distributes the res et to the rest of the boa rd by generating the CPU, PCI and IDE resets. This board can also be reset by an external switch that is connected to an onboard header.

Environmental Monitoring

The Winbond 83627HF hardware monitor device on the VP22 motherboard provides a number of useful system management features. These features include temperature, fan and voltage monitoring. The hardware monitor allows software to monitor voltages with its analog-todigital converters. An alarm sounds when the system voltage is ±10 percent.

CPU Temperature Monitor

An internal Pentium III thermal sensor monito rs microprocess or temperature. An overtemperature condition produces an alarm signal.

Open Chassis Alarm

The VP22 implements an open chassis circuit that can latch an open chassis event even when the system is turned off, as long as battery or standby power is still present. The open chassis interrupt is fed into the 83627HF hardware monitor chip. This circuit can only be reset via

BThermal Analysis

Board component temperatures are affected by ambient temperature, air flow, board electrical operation, and software operation. In order to evaluate the thermal perf ormance of a circuit board assembly, it is necessary to test the board under actual operating conditions. These operating conditions vary depending on system design.

While Motorola Computer Group (MCG) performs thermal analysis in a representative system to verify operation within specified ranges (see

Appendix A, Specific ations), you should evaluate the thermal performance

of the board in your application. This appendix provides sys tems integrators with inf ormation which can be

used to conduct thermal evaluations of the board in their specific system configuration. It identifies thermally significant components and lists the corresponding maximum allowa ble component oper ating temperat ures. It also provides example procedures for component-level temperature measurements.

Thermally Significant Components

The following table summarizes components that exhibit significant temperature rises. These are the components that should be monitored in order to assess thermal performance. The table also supplies the component reference designator and the maximum allowable operating temperature.

You can find components on the board by their reference designators as shown in Table B-1 and Figure B-1. Versions of the board that are not fu lly populated may not contain some of these components.

The preferred measurement location for a component may be junction, case, or air as specified in the tabl e. Junction temperature refers to the temperature measured by an on-chip thermal device. Case temperature

Component Temperature Measurement

The following secti ons outline general t emperature measurement methods. For the specific typ es of measu rements req uired for ther mal ev aluat ion of this board, see Table B-1.

Preparation

We recommend 40 AWG (American wire gauge) thermocouples for all thermal measurements. Larger gauge thermocouples can wick heat away from the components and disturb air flowing past the board.

http://www.motorola.com/computer/literature B-3

Page 58

Thermal Analysis

Allow the board to reach thermal equ ilibrium before ta king measurements. Most circuit boards will reach thermal equilibrium within 30 minutes. After the warm up period, monitor a small number of components over time to assure that equilibrium has been reached.

Measuring Junction Temperature

Some components have an on-chip thermal measuring device such as a thermal diode. For instructions on measuring temperatures using the

onboard device, refer to the component manufacturer’s documentation listed in Appendix C, Rela ted Documentation.

Measuring Case Temperature

Measure the case temperature at the center of the top of the component. Make sure there is good thermal contact between the thermocouple junction and the component. We recommend you use a thermally conductive adhesive such as Loctite 384.

If components are covered by mecha nical parts such as heats inks, you will need to machine these par ts to route the the rmocouple wire. Make sure tha t the thermocouple junction contacts only the electrical component. Also make sure that heatsink s la y fla t on el ectrical components. The following figure shows one method of machining a heatsink base to provide a thermocouple routing path.

Note Machining a heatsink base reduces the contact area between the

heatsink and the electrical component. You can partially compensate for this effect by filling the m achined areas with thermal grease. The gr ease should not contact the t hermocouple junction.
