4.1 Installation Considerations

NOTE:

The following installation notices and installation

considerations should be read and understood before

the motherboard is installed. All installation notices

pertaining to the installation of the motherboard should

be strictly adhered to. Failing to adhere to these

precautions may lead to severe damage of the

motherboard and injury to the person installing the

motherboard.

ROCKY-3786EV CPU Card

4.1.1 Installation Notices

Before and during the installation please DO the following:

 Read the user manual:

o The user manual provides a complete description of the ROCKY-3786EV

installation instructions and configuration options.

 Wear an electrostatic discharge cuff (ESD):

o Electronic components are easily damaged by ESD. Wearing an ESD cuff

removes ESD from the body and helps prevent ESD damage.

 Place the motherboard on an antistatic pad:

o When installing or configuring the motherboard, place it on an antistatic

pad. This helps to prevent potential ESD damage.

 Turn all power to the ROCKY-3786EV off:

o When working with the ROCKY-3786EV, make sure that it is

disconnected from all power supplies and that no electricity is being fed

into the system.

Before and during the installation of the ROCKY-3786EV DO NOT:

Page 68

 Remove any of the stickers on the PCB board. These stickers are required for

warranty validation.

ROCKY-3786EV CPU Card

 Use the product before verifying all the cables and power connectors are

properly connected.

 Allow screws to come in contact with the PCB circuit, connector pins, or its

components.

4.2 Unpacking

NOTE:

If any of the items listed below are missing when the

ROCKY-3786EV is unpacked, do not proceed with the

installation. Contact the ROCKY-3786EV reseller or

vendor.

MODEL NAME

4.2.1 Unpacking Precautions

Some components on ROCKY-3786EV are very sensitive to static electricity and can be

damaged by a sudden rush of power. To protect the ROCKY-3786EV from being

damaged, by ESD follow these precautions:

 Any person handling the ROCKY-3786EV should be grounded. This removes

static charge before the ROCKY-3786EV is touched. To remove static

electricity, wear a grounded wrist strap at all times or frequently touch any

conductive materials that are connected to the ground.

 Handle the ROCKY-3786EV by its edges. Do not touch the IC chips, leads or

circuitry unnecessarily.

 Do not place the PCB on top of the anti-static bag. Only the inside of the bag

is safe from static discharge.

4.2.2 Checklist

When unpacking the ROCKY-3786EV, please make sure that the package contains the

following items.

 1 x ROCKY-3786EV single board computer

Page 69

 1 x ATA66/100 flat cable

 2 x SATA cables

 1 x SATA power cable

 1 x RS232 cable

 1 x Keyboard/ PS2 mouse Y cable

 1 x Mini jumper pack

 1 x QIG (Quick Installation Guide)

 1 x Utility CD

If any of these items are missing, please contact the CPU card reseller or vendor and do

not proceed any further with the installation.

4.3 ROCKY-3786EV CPU Card Installation

ROCKY-3786EV CPU Card

WARNING:

Never run the motherboard without the appropriate heat

sinks and coolers. Heat sinks and coolers can be

ordered from IEI Technology or purchased separately.

WARNING:

Please note that the installation instructions described in

this manual should be carefully followed in order to

prevent damage to the ROCKY-3786EV components

and injury to the user.

Page 70

WARNING:

When installing electronic components onto the

ROCKY-3786EV CPU Card

ROCKY-3786EV always take anti-static precautions in

order to prevent ESD damage to the motherboard and

other electronic components like the CPU and DIMM

modules.

The following components must be installed onto the ROCKY-3786EV or connected to the

ROCKY-3786EV during the installation process.

 CPU cooling kit

 DIMM modules

 Peripheral device connection

4.3.1 CPU Installation

MODEL NAME

WARNING:

CPUs are expensive and sensitive components. When

installing the CPU please be careful not to damage it in

anyway. Make sure the CPU is installed properly and

ensure that a heat sink and CPU cooling fan are

properly installed before the ROCKY-3786EV is run.

If a heat sink and cooling fan are not properly installed

both the CPU and the board may be damaged.

To install Socket 370-pin CPU onto the ROCKY-3786EV, follow the steps below:

WARNING:

When handling the CPU, only hold it on the sides. DO

NOT touch the pins at the bottom of the CPU.

Page 71

Step 1: Inspect the CPU socket. Make sure there are no bent pins and make sure the

socket contacts are free of foreign material. If any debris is found, remove it with

compressed air.

Step 2: Open the CPU socket lever. Disengage the load lever by pressing the lever

down and slightly outward to clear the retention tab. Rotate the load lever to a

ROCKY-3786EV CPU Card

fully open position. (See

Step 3: Orientate the CPU properly. Make sure the IHS (Integrated Heat Sink) side is

facing upward. (See

Step 4: Correctly position the CPU. Match the Pin 1 mark with the cut edge on the CPU

socket. (See

Figure 4-1)

Figure 4-1: Install the CPU

Step 5: Insert the CPU. Gently insert the CPU into the socket. If the CPU pins are

properly aligned, the CPU should slide into the CPU socket smoothly

Step 6: Close the CPU socket. Re-engage the load lever by pushing it back to its

original position. Secure the load lever under the retention tab on the side of

CPU socket.Step 0:

4.3.2 Socket 370 Cooling Kit Installation

IEI provides an optional cooling kit designed for Socket 370 CPUs. The cooling kit is

comprises a CPU heat sink and a cooling fan.

NOTE:

The heat sink comes with a sprayed layer of thermal paste. Do not

CF-507-RS

CF-513-RS

accidentally wipe away the thermal paste while unpacking or installing the

heat sink. Thermal paste between the CPU and the heat sink is important

for optimum heat dissipation.

To install the cooling kit, please follow the steps below.

Step 1: Properly orient the cooling kit. Be sure the cooling kit is properly oriented before

attaching the mounting clips. The levered cooling kit mounting clip should be

aligned with the connecting tabs of the CPU socket closest to the DIMM socket.

Step 2: Attach the unlevered mounting clip first. Slip the unlevered mounting clip under

the connecting tab of the CPU socket. (See

Figure 4-3)

Page 73

Step 3: Secure the cooling kit in place. Gently push the levered mounting clip down with

a slight inward movement to snap it into place under the connecting tab. (See

Figure 4-3)

Step 4: Connect the fan cable. Connect the cooling kit fan cable to the fan connector on

the CPU card. Carefully route the cable and avoid heat generating chips and fan

blades.Step 0:

leaning outward (

Figure 4-4: Installing the DIMM Module

Figure 4-4).

Step 2: Slowly slide the DIMM module along the plastic guides on both ends of the

socket. Press the DIMM module down into the socket until it clicks into position

and the two handles have automatically locked the memory module into place

Figure 4-5).

(

Step 1: Find the ATA66/100 flat cable in the kit that came with the CPU card.

Step 2: Connect one end of the cable to the IDE1 connector on the CPU card. A keyed

pin on the IDE connectors prevents them from being connected incorrectly.

Step 3: Locate the red wire on the cable that corresponds to the pin 1 connector.

Step 4: Connect the cable to the HDD making sure that the pin 1 cable corresponds to

pin 1 on the connector.Step 0:

Only one connector in the set can be used.Step 0:

4.3.4.4 Parallel Port Connector (CN9)

The onboard parallel port connector (CN9) connects to a printer. The ROCKY-3786EV

comes with a multi-mode (ECP/EPP/SPP) parallel port. The parallel port interface features

a 26-pin flat-cable connector that requires an adapter cable if a traditional DB-25

connector is used. The parallel port interface can be re-assigned to LPT2 or LPT3 through

the BIOS configuration utility. The default interrupt channel is IRQ7. Select ECP or EPP

DMA mode using the BIOS configuration utility.

4.3.4.5 Audio Interface

ROCKY-3786EV CPU Card

AC’97 Audio signals are interfaced through a 10-pin flat-cable connector. The signals

include microphone line-in, line-in stereo and line-out stereo. An audio

10-pin-to-phone-jack adapter kit is required.

4.3.4.6 COM Port Connectors [CN2, CN8]

The ROCKY-3786EV provides two RS-232 serial ports interfaced through one 14-pin

male header. The serial ports facilitate the connection to serial devices or a

communications network, e.g., terminal console.

4.4 Chassis Installation

The CPU card can be mounted into a chassis only after the CPU, the cooling kit, and the

DIMM module have been installed, the internal peripheral connectors have been
