AirWorks AWK-4121 User’s Manual Introduction
Overview
The AWK-4121 outdoor wireless AP/bridge/client is an ideal 3-in-1 solution for industrial
applications that are hard to wire, too expensive to wire, or use mobile equipment that connect to a
TCP/IP network.
The AWK-4121 is rated to operate at temperatures ranging from -40 to 75°C, and its dust-tight and
weatherproof design is IP67-rated. An IP67 rating means the device is completely protected from
dust and is protected against the effects of immersion in water between 15cm and 1m in depth.
This means you can set up a WLAN or extend existing wired networks to outdoor locations and
still maintain a reliable connection. The AWK-4121 has two redundant DC power inputs for
increased reliability, can be powered via PoE, and is easy to deploy.

LED Indicators
The LEDs on the front panel of AWK-4121 allow you to identity the status and wireless settings
quickly.
The LED for FAULT indicates the system failure and user-configured events. If the AWK-4121
cannot retrieve the IP address from a DHCP server, the FAULT LED will blink at an interval of
one second.
The following table is a summary for the wireless settings and LED displays. You can check the
status of the AWK-4121 by reading these LEDs. More information about “Basic Wireless
Settings” is presented in Chapter 3.

AirWorks AWK-4121 User’s Manual Introduction
ATTENTION
When the LEDs for STATE (Green), FAULT, and WLAN all light up simultaneously and blink at
one-second intervals, it means the system failed to boot. This may be due to improper operation or
uncontrollable issues, such as an unexpected shutdown during firmware update. To recover the
firmware, refer to “Firmware Recovery” in Chapter 6.
Beeper
The beeper signals that the system is ready with two short beeps.
Reset Button
The RESET button is located on the bottom panel of the AWK-4121. You can reboot the
AWK-4121 or reset it to factory default settings by pressing the RESET button with a pointed
object such as an unfolded paper clip.
ySystem reboot: Hold the RESET button down for under 5 seconds and then release.
yReset 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-4121.
STEP 1: Remove the reset button cover. STEP 2: Using a pointed object, press and
hold the reset button.
