3 Getting Started

3.1 Panel Mounting

The STC-15W04 can be panel mounted using the 10 brackets
included with the device. Make sure there is adequate space
behind the panel for ventilation, and that the panel material and
thickness can support the weight of the device.

The mounting brackets can accommodate a maximum panel
thickness of 4mm.

NOTE:

NOTE:

1. Cut the panel opening using the appropriate cutout
dimensions: 380 x 235 mm.

2. Attach I/O cables to the device before installing into the
panel if rear access will be limited after installation (see
“I/O Panel Layout” on page 6.).

3. Place the device into the panel cutout.

4. Insert the mounting brackets into the slots on the sides
of the device as shown below.

STC-15W04

Getting Started 11

5. Hand-tighten the mounting brackets with a Phillips-head
screwdriver to secure it to the panel. Do not overtighten
the brackets to avoid damaging the device enclosure.

Do not overtighten the brackets as this may damage the device
enclosure.Always tighten the mounting brackets BY HAND to

CAUTION:

12 Getting Started

secure it to the panel.

STC-15W04

3.2 Connecting Power

Insert the positive and negative leads from the power supply as
marked on the chassis into the pluggable terminal block included
with the device.

Insert the pluggable terminal block into the 3-pole connector on
the I/O panel of the device. The device will power up when the
power supply is turned on.

Make sure the power supply is turned OFF when handling the
power leads.

WARNING:

Getting Started 13

3.3 CFast Card Installation

To install or remove the CFast card, loosen the captive screw until
it is possible to remove the CFast slot cover.

Do not completely remove the screw, as this will make it more
difficult to remove the slot cover.

NOTE:

NOTE:

Insert or remove the CFast card as required.

Replace the slot cover and tighten the scew.

14 Getting Started

STC-15W04

3.4 CMOS Battery Replacement

To change the CMOS backup battery, loosen the captive screw
until it is possible to remove the battery socket cover.

Do not completely remove the screw, as this will make it more
difficult to remove the slot cover.

NOTE:

NOTE:

Getting Started 15

Replace the CMOS battery with one of the same type (CR2450).

Replace the slot cover and tighten the scew.

4 BIOS

4.1 Introduction

The following chapter describes basic navigation for the AMI EFI
BIOS setup utility.

4.2 Starting the BIOS

To enter the setup screen, follow these steps:

1. Power on the motherboard

2. Press the < Delete > key on your keyboard when you

see the following text prompt:
< Press DEL to run Setup >

3. After you press the < Delete > key, the main BIOS setup

menu displays. You can access the other setup screens
from the main BIOS setup menu , such as Chipset and
Power menus.

STC-15W04

Note: In most cases, the < Delete > key is used to invoke the setup

screen. There are several cases that use other keys, such as
< F1 >, < F2 >, and so on.

BIOS 19

Setup Menu

The main BIOS setup menu is the first screen that you can navi­gate. Each main BIOS setup menu option is described in this
user’s guide.

The Main BIOS setup menu screen has two main frames. The left
frame displays all the options that can be configured. “Grayed”
options cannot be configured, “Blue” options can be.

The right frame displays the key legend. Above the key legend is
an area reserved for a text message. When an option is selected
in the left frame, it is highlighted in white. Often a text message will
accompany it.

Navigation

The BIOS setup/utility uses a key-based navigation system called
hot keys. Most of the BIOS setup utility hot keys can be used at
any time during the setup navigation process.

20 BIOS

NOTE:

NOTE:

STC-15W04

There is a hot key legend located in the right frame on most
setup screens.

The < F8 > key on your keyboard is the Fail-Safe key. It is not dis­played on the key legend by default. To set the Fail-Safe settings
of the BIOS, press the < F8 > key on your keyboard. It is located
on the upper row of a standard 101 keyboard. The Fail-Safe set­tings allow the motherboard to boot up with the least amount of
options set. This can lessen the probability of conflicting settings.

Hotkey Descriptions

Enter The < Enter > key allows you to display or change the setup

option listed for a particular setup item. The < Enter > key
can also allow you to display the setup sub-screens.

F1 The < F1 > key allows you to display the General Help

screen. Press the < F1 > key to open the General Help
screen.

BIOS 21

F2 The < F2 > key on your keyboard is the previous values key.

It is not displayed on the key legend by default. To set the
previous values settings of the BIOS, press the < F2 > key
on your keyboard. It is located on the upper row of a stan­dard 101 keyboard. The previous values settings allow the
motherboard to boot up with the least amount of options set.
This can lessen the probability of conflicting settings.

F3 The < F3 > key on your keyboard is the optimized defaults

key. To set the optimized defaults settings of the BIOS, press
the < F3 > key on your keyboard. It is located on the upper
row of a standard 101 keyboard. The optimized defaults se t­tings allow the motherboard to boot up with the optim ized de­faults of options set. This can lessen the probability of
conflicting settings.

F4 The < F4 > key allows you to save any changes you have

made and exit Setup. Press the < F10 > key to save your
changes. The following screen will appear:

22 BIOS

STC-15W04

Press the < Enter > key to save the configuration and exit.
You can also use the < Arrow > key to select Cancel and
then press the < Enter > key to abort this function and return
to the previous screen.

ESC The < Esc > key allows you to discard any changes you have

made and exit the Setup. Press the < Esc > key to exit the
setup without saving your changes. The following screen will
appear:

Press the < Enter > key to discard changes and exit. You can
also use the < Arrow > key to select Cancel and then press
the < Enter > key to abort this function and retu rn to the pre­vious screen.

BIOS 23

4.3 Main Setup

When you first enter the Setup Utility , you will enter the Main setup
screen. You can always return to the Main setup screen by select­ing the Main tab. There are two Main Setup options. They are
described in this section. The Main BIOS Setup screen is shown
below.

System & Board Info

The Main BIOS setup screen reports BIOS version, BIOS build
date and time, and total memory.

System Time/System Date

Use this option to change the system time and date. Highlight Sys­tem Time or System Date using the < Arrow > keys. En ter new val­ues using the keyboard. Press the < Tab > key or the < Arrow >
keys to move between fields. The date must be entered in MM/
DD/YY format. The time is entered in HH:MM:SS format.

The time is in 24-hour format. For example, 5:30 A.M. appears
as 05:30:00, and 5:30 P.M. as 17:30:00.

NOTE:

NOTE:

24 BIOS

STC-15W04

4.4 Advanced BIOS Setup

Select the Advanced tab from the setup screen to enter the
Advanced BIOS Setup screen. You can select any of the items in
the left frame of the screen, such a s SuperIO Conf iguration, to go
to the sub menu for that item. You can display an Advanced BIOS
Setup option by highlighting it using the < Arrow > keys. The
Advanced BIOS Setup screen is shown below.

The sub menus are described on the following pages.
