3. Hardware Connection Description
In this chapter, we describe how to connect the BXP-A100 to the network and to various devices.
Installing the BXP-A100
The BXP-A100 computer comes with two wall-mounting brackets. Attach the brackets to the computer using
three screws on each side as indicated in the diagram.
Fastening Torque: 10 Kgf-cm
The six screws for the mounting brackets are included in the product package. Refer to the following
illustrations for detailed specifications.
To mount the BXP-A100 computer to a wall or cabinet, use two screws on each side for the mounting
brackets as shown in the illustration.
NOTE
The four screws for attaching the wall-mounting brackets to the wall or cabinet are NOT included in the
product package; they need to be purchased separately.

BXP-A100 Series Hardware User Manual
13
The specifications of the 4 screws to be purchased separately is indicated in the
diagram.
After mounting the BXP-A100 computer using the wall-mounting kit and fastening the 4 screws to fix the
mounting brackets to the wall or cabinet, push the computer downwards to ensure that the device is
securely fixed to the mounting surface.
NOTE
This computer is intended to be installed only in an area with restricted access. In addition, for safety
reasons, the computer should be installed and handled only by qualified and experienced professionals.

ATTENTION
Safety First!
Be sure to disconnect the power cord before installing and/or wiring your BXP-A100.
Wiring Caution!
Calculate the maximum possible current in each power wire and common wire. Observe all electrical codes
dictating the maximum current allowable for each wire size. If the current goes above the maximum
ratings, the wiring could overheat, causing serious damage to your equipment.
Temperature Caution!
Be careful when handling the unit. When the unit is plugged in, the internal components generate heat,
and consequently the outer casing may feel hot to the touch.
Connecting the Power
The BXP-A100 computer is provided with 2-pin power input connectors in a terminal block on the front
panel. Insert the power-cord wires into the connectors and tighten them to secure the wires in place. Push
the power button. The power LED will light up to indicate that power is being supplied to the computer. It
should take about 30 to 60 seconds for the operating system to complete the boot-up process.

The power input specification is given below:
•The DC power source rating is 12 VDC @ 6.65 A or 24 VDC @ 3.30 A
•A minimum wire gauge of 18 AWG is required.
For surge protection, connect the grounding connector located below the power connector with the earth
(ground) or a metal surface.
NOTE
This computer is intended to be supplied by a UL Listed Power Unit “LPS” (or “Limited Power Source”)
rated 12 V @6.65 A min., 24 V @3.30 A min., and minimum Tma = 60˚C. If you need assistance with
purchasing a power adapter, contact the Moxa technical support team.
NOTE
If using Class I adapter, the power cord adapter should be connected to a socket outlet with an earthing
connection or the power cord and adapter must comply with Class II construction.

BXP-A100 Series Hardware User Manual

ATTENTION
Before connecting the BXP-A100 computer to the DC power inputs, make sure the DC power source
voltage is stable.
•The wiring for the input terminal block shall be installed by a skilled person.
•Wire type: Cu
•Only use 18-12 AWG wire size and a torque value of 0.5 N-m.
•Use only one conductor in a clamping point between the DC power source and the power input.
警告
為避免電磁干擾，本產品不應安裝或使用於住宅環境。
Communication Connections
Connecting to the Network
Connect your network cable to the computer’s Ethernet port. The other end of the cable should be
connected to your Ethernet network. When the cable is properly connected, the LEDs on the computer’s
Ethernet port turn on to indicate a valid connection.
The BXP-A100 computer has 2, 4, or 10 10/100/1000 Mbps Ethernet ports with RJ45 connectors on the
front panel. Refer to the following table for the pin assignments:

4. BIOS Setup
In this chapter, we describe the BIOS settings for the BXP-A100 computer. The BIOS is a set of input/output
control routines for peripherals to initialize the basic settings. The BIOS helps boot the system before the
operating system is loaded. The BIOS setup allows the user to modify the system configuration for basic
input/output peripherals. All the configurations are stored in the CMOS RAM, which has a backup battery in
case the computer is not connected to a power source. Consequently, the data stored in the CMOS RAM is
retained when the system is rebooted, or the power is disconnected.
Entering the BIOS Setup
To enter the BIOS setup utility, press the F2 key while the system is booting up. The main BIOS Setup
screen will appear. You can configure the following settings on this screen.
•Continue: Continue to boot up
•Boot Manager: Select the device for boot up
•Device Management: Enter the device configuration menu
•Boot From File: Select the UEFI boot up file
•Administer Secure Boot: Enter the Secure Boot menu
•Setup Utility: Enter the BIOS configuration menu
Select F2 to enter the BIOS configuration.
