AWK-5222 User’s Manual Getting Started

2-2

First-time Installation and Configuration

Before installing the AWK-5222, make sure that all items in the Package Checklist are in the box .
In addition, you will need access to a notebook computer or PC equipped with an Ethernet port.
The AWK-5222 has a default IP address that you must use when connecting to the device for the
first time.

Step 1: Select the power source.

The AWK-5222 can be powered by DC power input or PoE (Power over Ethernet). The
AWK-5222 will use whichever power source you choo se.

NOTE: The ITE unit is to be connected only to PoE networks without routing to the outside
plant.

Step 2: Connect the AWK-5222 to a notebook or PC.

Since the AWK-5222 supports MDI/MDI-X auto-sensing, you can use either a straight-through
cable or crossover cable to connect the AWK-5222 to a computer. If the LED indicator on
AWK-5222’s LAN port lights up, it means the connection is established.

Step 3: Set up the computer’s IP address.

Set an IP address on the same subnet as the AWK-5222. Since the AWK-5222’s default IP address
is 192.168.127.253, and the subnet mask is 255.255.255.0, you shou ld set the IP address of the
computer to 192.168.127.xxx.

NOTE

After you select Maintenance Æ Load Factory Default and click the Submit button, the
AW K-5222 will be reset to factory default settings and the IP address will be also reset to

192.168.127.253.

AWK-5222 User’s Manual Getting Started

Step 4: Use the web-based manager to configure AWK-5222

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:
User Name: 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, you can see that the web page is refreshed, and the
string “(Update)” and a blinking reminder will be shown on the upper-right corner of web page,
as follow.

To make the changes effective, click Restart and then Save and Restart after you change the
settings. About 30 seconds are needed for the AWK-5222 to complete its restart process.

AWK-5222 User’s Manual Getting Started

2-4

Step 5: Select the operation mode for the AWK-5222.

By default, the AWK-5222’s operation mode is set to Wireless redundancy. You can change the
setting in Wireless Settings Æ Operation mode if you would like to use the Wireless bridge or
AP-Client mode instead. Detailed information about configuring the AWK-5222’s operation can
be found in Chapter 3.

Step 6: Test communications.

We will describe 2 test methods to make sure the network connection has been established. Please
refer to the following section for more details.

Communication Testing

After installation, you can run a sample test to make sure the AWK-5222 and wireless connection
are functioning normally. Two testing methods are explained in the following sections. Use the
first method if you are using only one AWK-5222 device, and use the second method if you are
using two or more AWK-5222s.

Testing Method for one AWK-5222

If you are only using one AWK-5222, you will need a second notebook computer equipped with a
WLAN card. Configure the WLAN card to connect to the AWK-5222 (NOTE: the default SSID is

MOXA_1), and change the IP address of the second notebook (B) so that it is on the same subnet

as the first notebook (A), which is connected to the AWK-5222.
After configuring the WLAN card, establish a wireless connection with the AWK-5222 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-5222 User’s Manual Getting Started

2-5

Testing Method for two or more AWK-5222s

If you have two or more AWK-5222s, you will need a second notebook computer (B) equipped
with an Ethernet port. Use the default settings for the first AWK-5222 connected to notebook A
and change the second or third AWK-5222 connected to notebook B to Client mode. Then,
configure the notebooks and AWK-5222s 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.

Time Settings

The AWK-5222 has a time calibration function based on information from an NTP server or user
specified Date and Time information. Functions such as Auto warning can add real-time
information to the message.

Current local time shows the AWK-5222’s system time when you open this web page. You can
click on the Set Time button to activate the update after setting up the date and time parameters.
An “(Updated)” string will appear to indicate that the change is complete. Local time settings will
be immediately activated in the system without running Save and Restart.

NOTE

The AWK-5222 has a real time clock (RTC). Users are strongly recommended to upd ate the
Local time for the AWK-5222 after initial setup or long-term shutdown, especially when the
network does not have an Internet connection for accessing the NTP server or there is no NTP
server on the LAN.

Wireless Settings

The essential settings for wireless networks are presented in this function group. Settings must be
properly set before establishing your wireless network.

Operation Mode

The AWK-5222 supports three operation modes th at are used for different wireless network
applications:

Wireless Redundancy

In traditional architectures, most vendors only provide a single RF AP and Client, in which the AP
connects one or more Clients to the network. Since the AP and Client are connected by a single RF
connection, if the RF connection is disconnected the system or network behind the Client will be
disconnected, too.

AWK-5222 User’s Manual Other Console Configurations

3-9

With the new wireless redundancy technology, you can set up a redundant wireless connection
between a redundant client device and a redundant AP device. The redundant structure involves
using the AWK-5222’s two RF modules to set up two independent wireless connections between
the redundant client and redundant AP devices. If either of the two wireless connections fails,
the other wireless connection will continue transmitting packets between the redundant client and
redundant AP devices. In addition to carrying one or more redundant clients, standard single RF
clients can also associate with the redundant AP. One of the biggest advantages of the
AWK-5222’s wireless redundancy mode is that you can expect “zero data loss.”

Wireless Bridge

A bridge is a network component that connects two networks. AWK-5222’s bridge operation is
based on the AP (master) and Client (Slave) concept. Both sides of the connection must have the
same RF type, SSID, and security settings.

For single RF mesh networks, we can use WDS to establish a static bridge link. In this case, the
APs at both ends of the WDS link must be configured manually with each other’s MAC addresses.
The performance of a single RF bridge will be poor if more nodes are added.

The AWK-5222’s dual RF bridge concept is different from using a single RF, because the
AWK-5222 has dual RFs, and offer users a cascade link to bridge the two ends without narrowing
down the throughput.

WLAN 1/WLAN 2 Operation mode

Setting Description Factory Default

Master Master can build a connection with a

Slave that has the same RF type,
SSID, and security settings.

Some applications already have existing Clients in the environment. The AWK-5222 not only can
carry dual RF clients, but also single RF or existing Clients to the Ethernet LAN. This function is
available in Wireless Redundancy mode’s Redundant AP, or Wireless Bridge mode’s Master
page. Descriptions of other operation modes can be found in the “Basic Wireless Settings” section.
