CHAPTER

Hardware
Configuration

This chapter provides background
information on the PCA-6185. It will
show you how to configure the card to
match your application and prepare it
for installation into your PC.

1

Chapter 1 Hardware Configuration

1.1 Introduction

The PCA-6185 Series all-in-one industrial grade single CPU card uses
Intel's high performance Pentium® 4 processor, together with the Server­Works' GC-SL chipset. The card features two separate 64-bit PCI-X bus,
one for internal deviced and one for external add-on cards. The dual PCI­X bus ensures the operation of internal devices not to be influenced by
external add-on cards.

The PCA-6185 supports Pentium 4 or Celeron CPU with 533 and 400
MHz front side bus. Based on the NetBurst™ microarchitecture, the
CPU is equipped with 512, 256 or 128 KB on-CPU full-speed cache
memory, providing higher performance than ever before. The 3 DIMM
memory sockets support up to 4 GB DDR200/266 registered SDRAM,
fullfiling the demand on computing performance of most applications.
The PCA-6185 Series features powerful on-board I/O functions such as
single or dual gigabit Ethernet ports and dual channel Ultra 320 SCSI
interface. This makes it an ideal choice for applications that require both
high performance and full functionality.

It has two EIDE interfaces (for up to four devices) and a floppy disk drive
interface (for up to two devices). Other features include two RS-232
serial ports (16C550 UARTs with 16-byte FIFO or compatible), one
enhanced parallel port (supports SPP/EPP/ECP) and four USB (Universal
Serial Bus) 1.1 ports. The PCI enhanced IDE controller supports ATA 33/
66/100 and PIO Mode 4 operation. This provides data transfer rates of up
to 100 MB/sec. System BIOS supports boot-up from an IDE CD-ROM,
SCSI CD-ROM, LS-120, IDE HDD, SCSI HDD, ZIP-100, USB, LAN,
and FDD.

A backup of CMOS data is stored in the Flash memory, which protects
data even after a battery failure. Also included is a 63-level watchdog
timer, which resets the CPU or generates an interrupt if a program cannot
be executed normally. This enables reliable operation in unattended envi­ronments.

The remote management interface enables the PCA-6185 to be managed
through Ethernet when it is connected to the SNMP-1000 Remote HTTP/
SNMP System Manager.

Note: Some of the features mentioned above are not available with all models. For

more information about the specifications of a particular model, see Section

1.3 Specifications.

PCA-6185 User’s Manual 2

1.2 Features

1. High performance PCI bus: The PCA-6185 provides three inde­pendent PCI buses: one 32-bit, 33 MHz PCI bus and two 64-bit
PCI-X buses. The 32-bit bus is used for on-board VGA controller.
One of the two high performance PCI-X bus is used for onboard
Gigabit Ethernet and SCSI controllers. The other PCI-X bus is
available for user's add-on cards through the edge connector. This
PCI-X bus is compatible with PCI bus and capable to operate at dif­ferent speed: 32-bit/33 MHz, 32-bit/66MHz, 64-bit/33 MHz or 64­bit/66 MHz.

2. Fan status monitoring and alarm: To prevent system overheating
and damage, the CPU fan can be monitored for speed and failure.
The fan is set for its normal RPM range and alarm thresholds.

3. Temperature monitoring and alarm: To prevent system over-
heating and damage, the CPU card supports processor thermal
sensing and auto-protection.

4. Voltage monitoring and alarm: System voltage levels are moni­tored to ensure stable current flows to critical components. Voltage
specifications will become even more critical for processors of the
future. Thus monitoring will become ever more necessary to ensure
proper system configuration and management.

5. ATX soft power switch: Through the BIOS, the power button can
be defined as the "Standby" (aka "Suspend" or "Sleep") button or as
the "Soft-Off" button (see Soft-off by PWR-BTN, Setion 3.7.8)
Regardless of the setting, pushing the power button for more than 4
seconds will enter the Soft-Off mode.

6. Message LED: Chassis LEDs now act as information providers.
The way a particular LED illuminates indicates the stage the com­puter is in. A single glimpse provides useful information to the
user.

7. CMOS RAM backup: When BIOS CMOS setup has been com­pleted, data in the CMOS RAM is automatically backed up to the
Flash ROM. This is particularly useful in industrial environments
which may cause soft errors. Upon such an error occurring, BIOS
will check the data, and automatically restore the original data for
booting.

PCA-6185 User’s Manual 10

1.6 Safety Precautions

Warning! Always completely disconnect the power cord

from your chassis whenever you work with the
hardware. Do not make connections while the
power is on. Sensitive electronic components
can be damaged by sudden power surges. Only
experienced electronics personnel should open
the PC chassis.

Caution! Always ground yourself to remove any static

charge before touching the CPU card. Modern
electronic devices are very sensitive to static
electric charges. As a safety precaution, use a
grounding wrist strap at all times. Place all elec­tronic components in a static-dissipative surface
or static-shielded bag when they are not in the
chassis.

1.7 Jumper Settings

This section provides instructions on how to configure your card by set­ting jumpers. It also includes the card's default settings and your options
for each jumper.

1.7.1 How to set jumpers

You configure your card to match the needs of your application by setting
jumpers. A jumper is a metal bridge that closes an electrical circuit. It
consists of two metal pins and a small metal clip (often protected by a
plastic cover) that slides over the pins to connect them. To “close” (or
turn ON) a jumper, you connect the pins with the clip. To “open” (or turn
OFF) a jumper, you remove the clip. Sometimes a jumper consists of a set
of three pins, labeled 1, 2, and 3. In this case you connect either pins 1
and 2, or 2 and 3.

A pair of needle-nose pliers may be useful when setting jumpers.

1.7.2 CMOS clear (J1)

The PCA-6185 CPU card contains a jumper that can erase CMOS data
and reset the system BIOS information. Normally this jumper should be
set with pins 1-2 closed. If you want to reset the CMOS data, set J1 to 2-3

1.8 System Memory

The top-left edge of the PCA-6185 contains three sockets for 184-pin
dual inline memory modules (DIMMs). All these sockets accept only 2.5
V registered DDR SDRAM. Registered DIMMs are available in capaci­ties of 128, 256, 512, 1024 or 2048 MB. The sockets can be filled in any
combination with DIMMs of any size, with the limitation of the total
memory capacity of 4 GB.

1.8.1 Sample calculation: DIMM memory capacity

Suppose you install a 128 MB DIMM into your PCA-6185's socket 1 and
a 256 MB DIMM into sockets 2 and 3. Your total system memory is 640
MB, calculated as follows:

Table 1.6: DIMM memory capacity sample calculation

Socket number 184-pin DIMM memory Total memory
1 128 MB x 1 128 MB
2 256 MB x 1 256 MB
3 256 MB x 1 256 MB

Total memory: 640 MB

1.8.2 Supplementary information about DIMMs

Your PCA-6185 can accept only registered DDR SDRAM memory mod­ules. The register on the memory module secures reliable operation of
high memory capacity under high speed. Also note:

• Please use only DDR compliant registered DIMMS.

Most systems will not even boot if non-compliant modules are

used. This is due to strict timing issues involved at this speed.

• You can find two or three additional register ICs on a registered

SDRAM. These ICs are relatively smaller than the SDRAM ICs.

• Registered SDRAM are usually with ECC function. Modules with

9 or 18 SDRAM chips support ECC; modules with 8 or 16

SDRAM chips do not support ECC.

1.9 Memory Installation Procedures

To install DIMMs, first make sure the two handles of the DIMM socket
are in the "open" position. i.e. The handles lean outward. Slowly slide the
DIMM module along the plastic guides on both ends of the socket. Then
press the DIMM module right down into the socket, until you hear a
click. This is when the two handles have

PCA-6185 User’s Manual 14

automatically locked the memory module into the correct position of the
DIMM socket. To remove the memory module, just push both handles
outward, and the memory module will be ejected by the mechanism in the
socket.

1.10 Cache Memory

Since the second level (L2) cache has been embedded into the Intel®
Pentium® 4 processor, you do not have to take care of either SRAM chips
or SRAM modules. The built-in second level cache in the Pentium® 4
processor yields much higher performance than the external cache memo­ries. The cache size in the Intel® Pentium® 4 processor is 256 or 512 KB,
depending on the type of CPU.

1.11 CPU Installation

The PCA-6185 provides socket 478 for an Intel® Pentium® 4 processor.
The CPU on the board must have a fan or heat sink attached, to prevent

overheating.

Warning! Without a fan or heat sink, the CPU will overheat

and cause damage to both the CPU and the
motherboard.

To install a CPU, first turn off your system and remove its cover. Locate
the processor socket 478.

1. Make sure the socket 478 lever is in the upright position. To raise
the lever, pull it out to the side a little and raise it as far as it will go.

2. Place the CPU in the empty socket. Follow the instructions that
came with the CPU. If you have no instructions, complete the fol­lowing procedure. Carefully align the CPU so it is parallel to the
socket and the notches on the corners of the CPU correspond with
the notches on the inside of the socket. Gently slide the CPU in. It
should insert easily. If it does not insert easily, pull the lever up a
little bit more.

15 Chapter 1

3. Press the lever down. The plate will slide forward. You will feel
some resistance as the pressure starts to secure the CPU in the
socket. This is normal and will not damage the CPU.

Connecting
Peripherals

This chapter tells how to connect
peripherals, switches, and indicators to
the PCA-6185 board.

Chapter 2 Connecting Peripherals

2.1 Primary (CN1) and Secondary (CN2) IDE Connec­tors

CN2

CN1

You can attach up to four IDE (Integrated Drive Electronics) drives to the
PCA-6185’s built-in controller. The primary (CN1) and secondary (CN2)
connectors can each accommodate two drives.

Wire number 1 on the cable is red or blue and the other wires are gray.
Connect one end to connector CN1 or CN2 on the CPU card. Make sure
that the red/blue wire corresponds to pin 1 on the connector (in the upper
right hand corner). See Chapter 1 for help finding the connector.

Unlike floppy drives, IDE hard drives can connect in either position on
the cable. If you install two drives to a single connector, you will need to
set one as the master and the other as the slave. You do this by setting the
jumpers on the drives. If you use just one drive per connector, you should
set each drive as the master. See the documentation that came with your
drive for more information.

Connect the first hard drive to the other end of the cable. Wire 1 on the
cable should also connect to pin 1 on the hard drive connector, which is
labeled on the drive circuit board. Check the documentation that came
with the drive for more information.

Connect the second hard drive to the remaining connector (CN2 or CN1),
in the same way as described above.
