1. About This Manual
Thank you for purchasing a Moxa’s AWK-3252A Series/AWK-4252A Series/AWK-1151C Series product,
referred to as 'AWK Series" in this manual. Read this user’s manual to learn how to connect your Moxa
product with various interfaces and how to configure all settings and parameters via the user-friendly web
interface. Note that the web interface screenshots shown in this manual use the AWK-3252A Series for
reference. Since all AWK Series use the same firmware image, the screenshots will be identical for all
models, with the exception of the model name.
Three methods can be used to connect to the Moxa’s device, which all will be described in the next two
chapters. See the following descriptions for each chapter’s main functions.
Chapter 2: Getting Started
In this chapter, we explain the instruction on how to initialize the configuration on Moxa’s product. We
provide three interfaces to access the configuration settings: RS-232 console interface, SSH/Telnet CLI
(Command Line Interface), and web interface.
Chapter 3: Web Interface Configuration
In this chapter, we explain how to access the Moxa AWK-3252A’s various configuration, monitoring, and
management functions. These functions can be accessed through a web browser, or through the command
line console (CLI). In this manual, we describe how to configure the AWK Series functions via the web
interface, which provides the most user-friendly way to configure a Moxa device. For more information on
how to configure the AWK Series using the command line interface, refer to the AWK Series Command Line
Interface User Manual.

Configuration Reminders
In this section, several examples will be used to remind users when configuring the settings for Moxa’s AWK
Series.
A: About Mandatory Parameters
•The items with asterisks mean they are mandatory parameters that must be provided. In the figure
above, the parameters for Entry Status, Destination, and Interface are required to be able to save or
apply the configuration.
•If an item is marked in red means this item has been skipped. You need to fill in the parameters or you
cannot apply or create the function.
•Some parameter values will be limited to a specific range. If the values exceed the range, it cannot be
applied or created.
•Configuration input fields universally do not allow the following special characters: backslash (\),
apostrophe ('), double quotes ("), backtick (`).
B: Preconfiguring Settings
Some function settings can be configured while the function is disabled. These changes will take effect when
the function is enabled, without having to reconfigure the settings again. For example, on the SNMP
configuration page, users can configure the SNMP Account List settings while SNMP is disabled. When SNMP
is enabled, the previously configured Account List settings will take effect.

Reset Button
Depending on the AWK Series model, the Reset is located on the side panel (AWK-4252A), top panel (AWK-
3252A), or bottom panel (AWK-1151C). You can reboot the AWK series or reset it to factory default settings
by pressing the RESET button with a pointed object such as an unfolded paper clip.
•System reboot: Hold down the Reset button for under 5 seconds and then release. The SYS LED will
blink at 1 Hz.
•Reset to factory default: Hold down the Reset button for over 5 seconds until the SYS LED starts
blinking green. Release the button to reset the AWK Series to its factory default settings. The SYS LED
will blink at 4 Hz.
•Abort the action: Hold the Reset button down for longer than 10 seconds and then release to abort
the reset action. The SYS LED will stop blinking and turn solid.
NOTE
The reset to default factory settings function of the reset button is disabled by default and must be
enabled in the web console. Refer to the Reset Button Active Duration section for more detailed
information.
Relay (AWK-3252A and AWK-4252A Only)
The AWK-3252A and AWK-4252A Series have one relay output which is used to forward system failures and
user-configured events.
The two wires attached to the relay contacts form an open circuit when a user-configured event is triggered.
If a user-configured event does not occur, the relay circuit will remain closed. For safety reasons, the relay
circuit is kept open when the device is not powered up.

First-time Installation and Configuration
Before installing the AWK Series, make sure that all items in the Package Checklist listed in the Quick
Installation Guide are in the box. You will need access to a notebook computer or PC equipped with an
Ethernet port.
NOTE
The images in the instructions below use the AWK-3252A Series interface for reference. The instructions are identical
for all supported AWK models.
Step 1: Select the power source.
The AWK Series can be powered by a DC power input or PoE (Power over Ethernet) if applicable.
NOTE
For PoE-capable models, when both a DC and PoE power source is connected, the DC input will be the
default primary power source while PoE will be secondary. Using both DC and PoE power sources at the
same time does not provide seamless power redundancy. In the event the DC power source goes down,
the AWK will perform a reboot to negotiate the PoE protocol before switching to the PoE source.
Step 2: Connect the AWK Series to a notebook or PC.
Since the AWK Series supports MDI/MDI-X auto-sensing, you can use either a straight-through or
crossover cable to connect the AWK Series to the computer. The LED indicator on the AWK Series'
LAN port will light up when a connection is established.
Step 3: Set up the computer’s IP address.
Choose an IP address on the same subnet as the AWK Series. Since the AWK Series' default IP
address is 192.168.127.253, and the subnet mask is 255.255.255.0, you should set the IP
address of the computer to 192.168.127.xxx.
Step 4: Access the homepage of the AWK.
Open your computer’s web browser and type https://192.168.127.253 in the address field to
access the AWK’s homepage. If successfully connected, the AWK’s interface homepage will
appear. Click NEXT.

16
Step 5: Choose your country or region. (Not applicable to -US models)
Select your country or region from the drop-down list and click NEXT.
Step 6: Create a user account and password.
There is no default user account and password. Enter the username, password, and email address
for your user account and click CREATE.

AWK Series User Manual

NOTE
The username and password are case-sensitive.
After creating your account, you will be automatically redirected to the login screen.
Step 7: Log in to the device.
Once the initialization message disappears (in red), enter your username and password and click
LOG IN.

Communication Testing
After installing the AWK Series you can run a sample test to make sure the AWK Series and the wireless
connection are functioning normally. Two testing methods are described below. Use the first method if you
are using only one AWK Series device as an AP and use the second method if you are using AWK Series
devices as Client and AP.
How to Test the AWK Series as an AP
AWK-3252A/AWK-4252A
If you are testing the AWK Series device as an AP, you will need a second notebook computer equipped with
a WLAN card. Configure the WLAN card to connect to the AWK Series and change the IP address of the
second notebook (Notebook B) so that it is on the same subnet as the first notebook (Notebook A), which is
connected to the AWK Series.
After configuring the WLAN card, establish a wireless connection with the AWK Series and open a DOS
window on Notebook B. At the prompt, type
ping <IP address of notebook A>
and then press Enter (see the figure below). A “Reply from IP address …” response means the
communication was successful. A “Request timed out.” response means the communication failed. In this
case, recheck the configuration to make sure the connections are correct.

AWK Series User Manual
19
How to Test the AWK Series as a Client
AWK-3252A/AWK-4252A/AWK-1151C
If you are testing the AWK Series as a Client, you will need a second notebook computer (Notebook B)
equipped with an Ethernet port as well as an AP connected to notebook A. Configure the AWK Series
connected to notebook B for Client mode with the correct SSID and credentials matching the target AP.
After setting up the testing environment, open a DOS window on notebook B. At the prompt, type:
ping <IP address of notebook A>
and then press Enter. A “Reply from IP address …” response means the communication was successful. A
“Request timed out” response means the communication failed. In this case, recheck the configuration to
make sure the connections are correct.
