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,
aect 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.

Initializing
After the PA1+ has been connected to the network via Ethernet cable, the red LED marked "Power"
will light up. The PA1+ begins to boot.
Initializing with DHCP
The Snom PA1+ has a built-in DHCP client. When DHCP is available in the network, the PA1+ will
initialize automatically.
1. The red LED begins to blink. The PA1+ is sending the DHCP request.
2. After the PA1+ has received an IP address and other network-related settings (netmask, IP
gateway, DNS server, etc.) from the DHCP server, the red LED stops blinking and glows red
steadily, indicating that the application is starting up.
3. When the PA1+ boot-up process is nished and the web interface is available, the green LED
lights up in addition to the red one.
4. Briey press the button labelled "IP/Reset" to listen to the oral announcement of the IP address
(in English) over the loudspeaker or headset.
5. Open a web browser on a PC connected to the same network as the PA1.
6. Type the IP address into the address bar after http:// and press "Enter" to open the PA1's web
interface.
7. Continue with "Security settings" on page 14.
Initializing without DHCP
If your network does not support DHCP, the Snom PA1+ will boot with the default settings. Please
obtain the network IP address and netmask and, if applicable, other required network settings from
your network administrator. The default settings are:
IP address: 192.168.0.2
Netmask: 255.255.0.0
1. The red LED begins to blink. The PA1+ is sending the DHCP request.
2. Press the button labelled "IP/Reset". The red LED continues to blink.
Note: It may take a few minutes before the PA1+ aborts the DHCP request and starts the
application with the default settings.
3. When the application is starting up with the default network settings, the red LED stops to blink
and glows red steadily.
4. When the PA1+ boot up process is nished and the web interface is available, the green LED lights
up in addition to the red one. You can now change the default settings manually.
Note: Briey press the button labelled "IP/Reset" to listen to the oral announcement of
the default IP address (in English) over the loudspeaker or headset.
5. Open a browser on a computer connected to the same network as the PA1+, and type the default
IP address in the address bar: http://192.168.0.2. The PA1+ web interface will be loaded into the
browser.
6. Click Advanced in the menu on the left side of the window. The Advanced page opens to the

Security settings
When the web interface is opened for the rst time upon initialization, you will see the Security page.
When you register the rst account, the SIP user name and password will be registered as the HTTP
user name and password. If you wish to change them later, you can do so on the PA1+'s web interface
> Advanced > QoS Security > HTTP Server.
Note:
- If you do not replace the default administrator password by an individual one, an
unauthorized third party could set an administrator password unknown to you. In such a
case, you would no longer be able to switch from user mode to administrator mode.
- If you set your own passwords, be sure to write them down and store them in a secure
place.
Without the administrator password, you will not be able to switch the web interface from
