2.2 Initial Setup
NOTE: This guide assumes that a PowerGrid 9141s will be the primary connection
to the modem / router and a PowerGrid 9141s-PoE will be used within the
network to connect to a PoE-capable device (E.g. Camera, Access Point, IP
Phone).
1. Ensure that your modem or router is powered on.
2. Plug a PowerGrid 9141s
unit into the power socket
closest to the modem/
router. The POWER LED
will blink GREEN.
3. Connect the PowerGrid 9141s unit to the LAN
port of the modem/router with an Ethernet
(RJ-45) cable. Wait 10 seconds for the
PowerGrid’s Ethernet LED and Power LED to
light up GREEN indicating a stable connection.

2.3 Device Connection
These steps show how to connect a PowerGrid 9141s-PoE to a network device.
Below we use a PoE camera as a network device.
1. Plug a PowerGrid 9141s-PoE unit into the power socket closest to the PoE
(IEEE 802.3af compliant) camera or other device. The Power LED on the
PowerGrid 9141s-PoE should light up GREEN.
2. Connect the PowerGrid 9141s-PoE to the camera with an Ethernet cable. The
Ethernet and PoE LEDs on the PowerGrid 9141s-PoE should light up GREEN.
3. The STATUS LED on the PowerGrid 9141s-PoE should now be RED, GREEN or
ORANGE.
4. If the STATUS LED is off, Press the “Config” button on each of the two PowerGrid
9141s and 9141s-PoE devices for 2-5 seconds. Upon successful connection of the
PowerGrid 9141s-PoE, the STATUS LED will light up GREEN.
5. If the connection process is not successful, please refer to the troubleshooting
steps in Chapter 3.
2.4 Adding a New Device
Follow steps 1-4 above to add additional PowerGrid 9141s-PoE devices to the network.
Press the “Config” button on the new device and one other PowerGrid device in the
network so they can pair and transmit data successfully.

2.5 How to use a power strip with the PG-9141s-PoE
If you must plug your adapter into a power strip, we suggest you use a basic power
strip as the more advanced ones have a filter that can interfere with the Powerline
signal.
SURGE PROTECTED POWER STRIPS: Avoid plugging PowerGrid
units into power strips with surge protection as this will reduce
network speed and may even prevent their use.
2.6 How to understand the STATUS LED colors
The STATUS LED displays quality of the network and provides important
information that will provide solutions to common questions, such as why a High
Definition (HD) movie is not showing or shows with pixels. The STATUS LED
indicator will vary its color depending on the estimated speed of the Powerline
connection. The speed is measured in Megabits Per Second (Mbps).
Color
Information
RED
Normal network traffic (ex. the connection speed is
between 1 and 40 Megabits per second).
ORANGE
Good network traffic (ex. the connection speed is
between 40 and 90 Megabits per second).
GREEN
Excellent network traffic (ex. the connection speed is
more than 90 Megabits per second).

Chapter 3: Troubleshooting
The following information should help you diagnose basic setup or installation
problems.
1) POWER LED BLINKS AND OTHER LEDs are OFF:The POWER LED blinks and
other LED lights switch off when PowerGrid 9141s-PoE(s) unit enters power saving
mode. This occurs 30 seconds after the Ethernet connection is lost (see below).
2) ETHERNET LED is OFF: If the Ethernet LED fails to light up, check that the LAN
port of the PowerGrid unit is connected firmly to the LAN port of the other device. To
check the condition of the Ethernet cable, use another cable to test the same
connection.
3) STATUS LED is OFF: Plug both PowerGrid units that you’re attempting to pair
into power outlets that are within the same room; both PowerGrid devices should
have an Ethernet cable connected to their respective devices (e.g. PC, Router, Set Top
Box, camera, etc…). After 10 seconds (approx, until all the LEDs of the device blink),
the STATUS LED should light up GREEN. If not, press the “Config” button on each
for 2-5 seconds and let go.
4) PoE LED is OFF: If the PoE LED fails to light up, check that the LAN port of the
PowerGrid unit is connected firmly to the LAN port of the PoE device. Also, the PoE
capable device needs to support the 802.3af standard and not other proprietary
standards.
*If you have tried all of the above and are still experiencing problems, you can reset
both devices (PG-9141s & PG-9141s-PoE) to factory default by using a pin to push in
the “Reset”button for 11 seconds (until all the LEDs of the device blink).

Chapter 4: Frequently Asked Questions
This Powerline adapter has been designed to be reliable and easy to use in creating
or extending your existing home network. However, should you experience any
problems, please refer to the list below to aid in troubleshooting.
1. What to do if the LEDs do not display as expected?
•Power indictor is flashing, the other indicators are off: PowerGrid
9141s-PoE went into power saving mode. It occurs 60 seconds after the
Ethernet signal connection stops.
•Ethernet LED is off: If the Ethernet LED does not light up, check or connect
your devices (PC, STB…etc.) to the port Ethernet PowerGrid to check
whether your Ethernet cable works. Alternatively, you can use another
similar cable.
•Status LED is off: After performing step 2. (for 2 single units to pair up), if
still not working, please do the following 2 steps:
Simple Connect: Press the CONFIG push button for more than 11
seconds on each of PowerGrid 9141s-PoE adapters then press the
CONFIG push button for 2-5 seconds on one adapter (the Power LED
should blink). Within 2 minutes, press the CONFIG push button for
2-5 seconds on the second adapter. After 10 seconds the two
adapters should communicate and the Status LED should be solid on
both adapters at the end of the pairing process.
Simple Pairing: Plug 2 PowerGrid 9141s-PoE adapters in to power
outlets, then connect these 2 devices directly to one another using
an Ethernet cable. Wait for the Ethernet LED to turn ON, and then
disconnect the Ethernet cable. The Status LED should be solid ON
both PowerGrid 9141s-PoE adapters at the end of the pairing
process.
2. How do I RESET to factory default settings?
If you have tried the FAQ above action 1., and you are still experiencing problems,
you can return both PowerGrid 9141s-PoE adapters to factory settings using the pin
by pressing (RESET) for 11 seconds (until all the LEDs of the adapter blink).
If the power LED on any of the PowerGrid 9141s-PoE units (in the network) does
not light up Green, press the Config button on the problem PowerGrid 9141s-PoE unit
for more than 10 seconds to disconnect it from the network. Then, see Chapter 2 for
Network Setup. If the problem persists, please contact your local agent for further
assistance.
3. Why is SDTV video not streaming?
•Check the STATUS indicator LED in the adapter connected to the STB.
•If the indicator is RED this means that the PLC link is not able to play
an SDTV streaming.
•Try to reposition the adapter into another outlet in order to obtain
an ORANGE or GREEN indication.
•If the indicator is ORANGE or GREEN, it should now be able to play
SDTV video.
•If the SDTV video still does not play, check the Ethernet cables and the
settings of devices connected to the PLC adapters (STB, router, PC,
video server, etc.).

13
4. How many PowerGrid 9141s-PoE could be installed in the home?
For each additional device (computer, modem, router…and so on) that you want to
connect to your home network, you will need add additional adapters PowerGrid
9141s-PoE and Ethernet cables, one for each device.
The maximum number of installed devices, is up to 10 in the same home network.
Maximum data transfer between devices, 95 MB /sec.
Poor quality of the wiring and the presence of interference will significantly reduce
the possible number of installed devices and data transfer rate.
5. Why is HDTV video not streaming?
•Check the status indicator LED in the adapter connected to the
set top box (STB).
•If the indicator is RED or ORANGE this means that the Powerline link is not
able to stream HDTV.
•Try to reposition the adapter in another outlet in order to obtain a GREEN
indication.
•If the indicator is GREEN, it should now be able to play a HDTV
video.
•If the LED is not GREEN check the Ethernet cables and the settings of
devices connected to Powerline adapters (STB, DSL router, PC, video server,
etc.).
N
OTE : If the HDTV video bandwidth is lower than 10Mbps, it may be possible
to stream the video with an ORANGE STATUS LED in some cases.
6. What if my Powerline Adapters don’t fit into the plug socket?
•Your Powerline Adapters might not fit because the sockets are too close to
the floor or are in the skirting board.
•The easiest way around this is to use a trailing power strip, and plug the
Adapter into the strip. Please make sure that the strip is not an anti-surge
adapter strip.
7. What if the house next door has Powerline Adapters as well?
•Each pair of Powerline Adapters has its own unique security key. This means
that your connection is secure and cannot be confused with anyone else’s.
8. Is it safe to leave the Powerline Adapters on all the time - is there any
danger of overheating?
•Powerline Adapters are CE and FCC certified and completely safe to leave
plugged in all the time. They may become slightly warm in use - this is
perfectly normal. However, you may wish to put them into standby when not
in use.

14
9. How much power do Powerline Adapters use and how much do they
cost each month in electricity?
•The adapters use 3.5 Watts when in use and 0.45 Watts in standby. Prices
vary between electricity suppliers.
10. How can I check that my Powerline Adapters are working
properly?
•Your Powerline Adapters are set to work together as a pair, and should
work perfectly out of the box. The best way to test them is to find a
double plug socket, and plug them in next to each other. Often the
best place to find a double plug socket is in your kitchen. Alternatively
plug them into a trailing extension strip (but not an anti-surge strip).
•When plugged in, after 10 seconds, the Powerline Adapters will
configure themselves so that each has a green status light.
•If the Powerline Adapters don’t configure themselves as above, you
need to follow the reset procedure (described above).
•When your Powerline Adapters are connected to a device the Ethernet
light should light up. When you’re using the service the Ethernet light
will flash. You may notice that the Status Light on one or both
Powerline Adapters changes to red or orange. This isn’t something to
worry about if you are not having any problems with your connection.
