1-6
ATTENTION
The FAULT, SIGNAL,CLIENT, BRIDGE, and WLAN LEDs lighting up simultaneously and blinking at
one-second intervals indicates that the system has failed to boot. This may be due to improper operation or
an uncontrollable factor, such as an unexpected shutdown during firmware update. Instructions on how to
recover the firmware can be found in Chapter 6 in the “Firmware Recovery” section.
Beeper
The beeper emits two short beeps when the system is ready.
Reset Button
The RESET button is located on the top panel of the AWK-3121. You can reboot the AWK-3121 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 the RESET button down for under 5 seconds and then release.
•Reset to factory default: Hold the RESET button down for over 5 seconds until the STATE LED starts
blinking green. Release the button to reset the AWK-3121.
Relay (Digital Output)
The AWK-3121 has one relay output consisting of the 2 terminal block contacts on the top panel, as shown
below. These relay contacts are 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 AWK-3121 is not powered up.

AirWorks AWK-3121 Getting Started
2-2
First-time Installation and Configuration
Before installing the AWK-3121, make sure that all items in the Package Checklist are in the box. You will need
access to a notebook computer or PC equipped with an Ethernet port. The AWK-3121 has a default IP address
that must be used when connecting to the device for the first time.
•Step 1: Select the power source.
The AWK-3121 can be powered by a DC power input or PoE (Power over Ethernet). The AWK-3121 will use
whichever power source you choose.
•Step 2: Connect the AWK-3121 to a notebook or PC.
Since the AWK-3121 supports MDI/MDI-X auto-sensing, you can use either a straight-through cable or
crossover cable to connect the AWK-3121 to a computer. The LED indicator on the AWK-3121’s 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-3121. Since the AWK-3121’s 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.
NOTE After you select Maintenance Load Factory Default and click the Submit button, the AWK-3121 will be
reset to factory default settings and the IP address will be reset to 192.168.127.253.
•Step 4: Use the web-based manager to configure the AWK-3121
Open your computer’s web browser and type http://192.168.127.253 in the address field to access the
homepage of the web-based Network Manager. Before the homepage opens, you will need to enter the user
name and password as shown in the following figure. For first-time configuration, enter the default user
name and password and then click on the Login button:
NOTE Default user name and password:
UserName: admin
Password: root
For security reasons, we strongly recommend changing the default password. To do so, select Maintenance
Password, and then follow the on-screen instructions to change the password.

NOTE After you click Submit to apply changes the web page will refresh (Updated) will appear on the page and a
blinking reminder will be shown on the upper-right corner of the web page:
To activate the changes click Restart and then Save and Restart after you change the settings. About 30
seconds are needed for the AWK-3121 to complete the reboot procedure.
•Step 5: Select the AWK-3121 operation mode.
By default, the AWK-3121’s operation mode is set to AP. You can change to Client mode in Wireless
Settings Basic Wireless Settings. Detailed information about configuring the AWK-3121’s operation
can be found in Chapter 3.
•Step 6: Test communications.
In the following sections we describe two test methods that can be used to ensure that a network
connection has been established.
Communication Testing
After installing the AWK-3121 you can run a sample test to make sure the AWK-3121 and wireless connection
are functioning normally. Two testing methods are described below. Use the first method if you are using only
one AWK-3121 device, and use the second method if you are using two or more AWK-3121 units.
How to Test One AWK-3121
If you are only using one AWK-3121, you will need a second notebook computer equipped with a WLAN card.
Configure the WLAN card to connect to the AWK-3121 (NOTE: the default SSID is MOXA), 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-3121.
After configuring the WLAN card, establish a wireless connection with the AWK-3121 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.

AirWorks AWK-3121 Getting Started
2-4
How to Test Two or More AWK-3121 Units
If you have two or more AWK-3121 units, you will need a second notebook computer (Notebook B) equipped
with an Ethernet port. Use the default settings for the first AWK-3121 connected to notebook A and change the
second or third AWK-3121 connected to notebook B to Client mode, and then configure the notebooks and
AWK-3121 units properly.
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.
