snom PA1+ User Manual Important information
Important information
Please read the instructions on safety and disposal and on how to set up and use the device before
using it and also give them to other users to read or inform those users of their contents. Save this
manual and do not give the device to third parties without it.
The nameplate is located at the bottom or rear of the product.
Safety instructions
Follow the instructions in this manual and other applicable documentation of the device.
• Warning: The product included (ITE) in this manual is to be connected only to PoE networks
without routing to the outside plant.
• The socket outlet for the power adaptor must be near the equipment and easily accessible.
• Mount the device only at heights not exceeding 2m.
• If the device is not supplied with power via an Ethernet cable, use only a power adapter expressly
recommended by Snom technology. Other power supplies may damage or destroy the device,
aect its behavior, or induce noise.
• Avoid placing the cables where people may trip over them or where they may be exposed to
mechanical pressure as this may damage them.
• This device is for indoor use only! NOT FOR OUTDOOR USE!
• Do not install the device in rooms with high humidity (for example, in bathrooms, laundry rooms,
damp basements). Do not immerse the device in water and do not spill or pour liquids of any kind
onto or into the device.
• Do not install the device in surroundings at risk for explosions (paint shops, for example). Do not
use the device if you smell gas or other potentially explosive fumes.
• Do not use the device during thunderstorms. Lightning striking the power grid may cause electric
shocks.
• Do NOT remove the device's power supply (Ethernet cable when using PoE, power adapter when
not using PoE) when the red light is on or blinking; a rmware update is ongoing. Cutting o the
device's power during a rmware update (red LED on, green LED o) will damage the rmware
and render the PA1+ inoperational. In such cases, it will need to be returned to the vendor for
resetting.
• SELV (Safety Extra Low Voltage) Compliance. Safety status of input/output connections comply
with SELV requirements.
Warning: To avoid electric shock, do not connect safety extra-low voltage (SELV) circuits to
teledevice-network voltage (TNV) circuits. LAN ports contain SELV circuits, and PSTN ports
contain TNV circuits. Some LAN and PSTN ports both use RJ-45 (8P8C) connectors. Use caution
when connecting cables.

against harmful interference when the equipment is operated in a commercial environment. This
equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in
accordance with the instruction manual, may cause harmful interference to radio communications.
Operation of this equipment in a residential area is likely to cause harmful interference in which case
the user will be required to correct the interference at the user’s expense.
WARNING: Changes or modications to this equipment not expressly approved by the party
responsible for compliance could void the user’s authority to operate the equipment.
Unauthorized opening, changing, or modifying the device will cause the warranty to lapse and
may also result in the loss of CE conformity and FCC compliance. In case of malfunction contact
authorized service personnel, your seller, or Snom .
Disposal of the device
This device is subject to European Directive 2012/19/EU and may not be disposed of with
general household garbage. If you do not know where to dispose the device at the end of its
lifespan, contact your municipality, local waste management provider, or vendor.
For countries outside the European Union
Disposal of electrical and electronic products in countries outside the European Union should be done
in line with local regulations. Please contact local authorities for further information.
Cleaning
To clean the device, use an anti-static cloth. Please avoid cleaning liquids as they might damage the
surface or internal electronics of the device.

Wallmounting
Note: The Ethernet cable must not be bent to avoid damage and loss of the network
connection. We recommend that you place the PA1+ so that the PoE connector is facing
toward the LAN port in your network. We also recommend that you place the PA1+ in a
location where you can see the LEDs from your desk or work station.
