Test
Accessory
User Guide
How it Works
The Test Accessory acts as the endpoint for a test
run by a NETSCOUT handheld network tester,
such as an AirCheck G2 Wireless Tester.
Powering On
The Test Accessory operates with either
Power over Ethernet (PoE) or the following AA
battery types: Alkaline (shipped with product),
Rechargeable NiMH, or Lithium.
1. Insert two AA batteries into the back of your
Test Accessory.
2. Ensure that you have an Ethernet cable
connected to an active network with access to
the Internet.
3. If PoE is available on your network
connection, the unit starts up automatically.
If you are using batteries only, press and hold
the power button for two seconds to turn on
the unit.
As soon as you power on the Test Accessory, all of
the LED symbols illuminate yellow for 15 seconds
while the unit starts up.
Then, the accessory attempts to connect to
your network, lighting up each LED with the
corresponding connection step.
NOTE: Once you connect to the cloud, the Test
Accessory may automatically update with the
latest software. See the Software Update LED
Sequence below for more information.

NETSCOUT Handheld
Network Tester
NETSCOUT
Test
Accessory
The Test Accessory works
together with other
NETSCOUT Handheld
Network Testers to run
network performance and
availability tests.
This User Guide covers
the basics of connecting
and conguring your
Test Accessory. See the
user documentation for
your main testing tool for
information on running
specic tests and viewing
results.
Detailed LED Behavior
Connection LED Sequence
1. If the unit is running
on PoE, the Power
light (lightning bolt)
illuminates GREEN. If it
is running on batteries,
the Power light stays
YELLOW. If the batteries
need replacing, the
Power light turns RED.
2. The Link status light
(chain link) flashes
GREEN until a link is
established and then
stays solid GREEN.
3. The unit requests an
IP Address and the
DHCP light flashes
GREEN. If a usable IP
address is acquired,
the DHCP light turns
solid GREEN. If the unit
acquires a duplicate IP
address, the DHCP light
turns YELLOW, and if
no IP address can be
acquired, it turns RED.

4. The Test Accessory
communicates with
the default gateway
router. The Gateway
status light flashes
GREEN until it
connects with the
gateway; if successful,
it turns solid GREEN.
If the Test Accessory
cannot reach the
gateway, the light
turns solid RED.
5. The Test Accessory
attempts to communicate with the Link-Live
Cloud Service, and the cloud light flashes
GREEN to indicate internet connectivity.
Your Test Accessory may automatically update if
there is a newer software version available.
NOTE: Do not turn o or try to claim your Test
Accessory to Link-Live during the update process
or the update may fail.
Software Update LED
Sequence
1. First, all five lights flash
YELLOW.
2. Next, starting with the PoE
lightning bolt at the bottom
of the unit, each status light
begins to flash YELLOW in
sequential order up to the
Cloud status light, until all
five are flashing YELLOW
again for several seconds.
3. Then, the unit reboots;
starting with the Cloud
status light, each light
flashes GREEN sequentially
down to the PoE status light.
4. Finally, the Test Accessory
reconnects, beginning with
the PoE status light. Each
light blinks GREEN while
connecting.

Resetting to
Factory Defaults
CAUTION: Resetting a Test Accessory to factory
defaults erases all performance and conguration
data and unclaims it from Link-Live.
1. Ensure the unit is powered off, meaning all
LEDs are off.
2. Hold down the power button for
approximately 30 seconds.
As the unit resets, it begins with all ve status
lights illuminating solid YELLOW for about 15
seconds. Then, the LEDs ash GREEN sequentially
upward to the cloud light for another 15 seconds,
and nally all LEDs ash GREEN simultaneously.
3. Release the power button as soon as the
lights flash GREEN simultaneously, and
BEFORE they flash RED.
If you do not release the power button before the
LEDs ash RED, the LEDs turn YELLOW to indicate
a failed reset attempt, and you will have to start
the reset procedure over.
If the reset is successful, the Test Accessory will
shut down and power o.
