Page 10 VoIP gateway IP400 version 5.01
2.1.4 Commissioning and Installation of the IP 400
The following steps are required to commission the gateway:
• Wire up the connections as described above.
• Set the IP- interface parameters, see section 2.2 “Configuration of access to
the local network” from page 11.
• To define the operational configuration, see section 4 “Configuration of the IP
interfaces” from page 24.
The following sections are based on the assumption that the gateway is in the
same condition as delivered and that therefore the standard configuration is
loaded. We recommend restoring the standard configuration first, if you are not
sure about the state of the configuration (see section 2.2.1 “Generating the stand-
ard configuration” from page 11).
Note the section “Safety instructions for the IP 400” from page 138.
The IP 400 is suitable for wall mounting. The horizontal distance between the sus-
pension points is 12 cm. Take care not to damage the protective film of the PCB
when mounting the IP 400.
The devices can be stacked. Make sure there is adequate ventilation if the gate-
way is to be installed in a cabinet.
For installation in a 19" cabinet, there is a special frame available which can
accommodate two IP 400 gateways.

VoIP gateway IP400 version 5.01 Page 11
2.2 Configuration of access to the local network
The gateway is delivered with a standard configuration. In this configuration, the
gateway will try to configure the IP parameters via DHCP. The installed DHCP
client is thus active and the DHCP server, which is also incorporated, is deacti-
vated.
Ask your network administrator whether your network has a DHCP server.
Refer to section 2.2.4 “Setting the IP-interface parameters without DHCP” from
page 16 if there is no DHCP server in operation in your network or if, for some
other reason, you do not want to have automatic configuration via DHCP. In this
case your PC also needs to be provided with a twisted-pair Ethernet adapter
(10 Base-T for the IP 400).
Refer to section 2.2.3 “Setting the IP-interface parameters via DHCP” from
page 13, if a DHCP server is available.
In both cases you can access the gateway via Ethernet.
2.2.1 Generating the standard configuration
Bear in mind though, that you will lose all of the preceding configuration data as
a result of this procedure. If required, you can save the current configuration in a
file, beforehand.
Tip
You can return to the standard configuration at any time by pressing the reset
button, and holding it down for a few seconds. This takes about 5 seconds for
the IP 400.
That will result in the gateway being re-initialised and will be put into a special
reset mode. It can then be reset to normal operating mode by being switched
on and off.
Tip
Press the reset button again, briefly, to return the gateway to normal operat-
ing mode. In this case however, the DHCP server mode will be activated (see
from page 16 onwards), whereas the DHCP client mode (see page 13) will be
activated after switching the gateway on/off.

Page 12 VoIP gateway IP400 version 5.01
2.2.2 Switching on the gateway
The mains socket must be close to the device and easily accessible. The only way
of interrupting the power supply to the device is by removing the mains lead of
the device, or of the external power supply, from the mains socket.
The equipment is now powered up and the READY LED is illuminated.
Caution
Connect the gateway to the nearest wall socket using the supplied external
power supply (IP 400, 100-240 V).
Only use the external power supply. Other power supplies could damage the
gateway.

VoIP gateway IP400 version 5.01 Page 13
2.2.3 Setting the IP-interface parameters via DHCP
You can ask your network administrator to reserve a fixed IP address for the gate-
way via DHCP. Tell your administrator the hardware address of your gateway.
Please read the associated chapter about the serial number label for your gate-
way.
In the standard configuration, the gateway tries to configure via DHCP, each time
it is switched on. The configuration mode without DHCP is activated however each
time the reset button is pressed (not by switching on/off and not with the reset
command) (refer here to section 2.2.4 “Setting the IP-interface parameters with-
out DHCP” from page 16).
... for experts
• There are basically two ways of configuring an IP address for your gate-
way.
• When delivered from the factory, DHCP is in an automatic mode. You can
force the DHCP into automatic mode with a long reset (at least 3 seconds).
• With a short reset, DHCP server mode is activated and the gateway is allo-
cated the IP address 192.168.0.1.
• It is most definitely better to use the gateway in DHCP client mode. To do
this, you need a DHCP server in the network.
• If the power supply is interrupted, while the gateway is in automatic
mode, DHCP client mode will be activated. You will now be assigned an
IP address by the DHCP server in the network.
• You can display the allocated IP address as follows.
In the command line, enter C:> plus the following command:
nbtstat –R
nbtstat –a ip400-YY-YY-YY
Where the Ys should be replaced with the gateway's MAC address.
• Now start the web-based configuration, using the new IP address.
Tip
The most convenient way of configuring the IP interface parameters is via
DHCP, provided your network has a DHCP server.

Page 14 VoIP gateway IP400 version 5.01
Now, proceed as follows:
• Set the Ethernet switch on the back to the “connect to Hub” position.
• Connect the Ethernet RJ 45-connector of the gateway to the
RJ 45-connector of your Ethernet hub or switch using a twisted pair cable.
• Switch the gateway off and then on again, to activate the DHCP client.
The gateway will now be now assigned an IP address. If your network adminis-
trator has not set up a permanent IP address for you, you now have to find out
which IP address has been assigned. There are two ways of doing this:
• The simplest option is to ask your network administrator. They can find the
assigned IP address using the DHCP server administration program.
• The other option is to consult the gateway itself. Once the configuration has
been carried out successfully, the gateway registers the NetBIOS name
“ip400-XX-XX-XX“. “XX-XX-XX” must be replaced by the last 6 hexadeci-
mal numerals from the serial number. Please read the associated chapter
about the serial number label for your gateway.
You can now find out which IP address has been assigned, using the com-
mand “nbtstat” on a Windows PC.
C:> nbtstat –
C:> nbtstat –a ip400-XX-XX-XX
NetBIOS remote machine name table
Name Type Status
--------------------------------------------
IP400-XX-XX-XX<00> UNIQUE Registered
195-226-104-217<00> UNIQUE Registered
IP400-XX-XX-XX<00> UNIQUE Registered
MAC address = 00-90-33-XX-XX-XX
In the above example, the gateway has the IP address 195.226.104.217.
Tip
The IP address cannot be displayed with nbtstat, if your NetBIOS environment
is configured exclusively to resolve names via WINS. Consult your network
administrator to configure the NetBIOS name resolution appropriately, if the
nbtstat command is unable to find your gateway.

VoIP gateway IP400 version 5.01 Page 15
Under Linux, you can use the “nmblookup” command for this purpose, provided
the “SAMBA” package has been installed:
[dvl@cobalt ~ 2] $. nmblookup ip400-XX-XX-XX
Got a positive name query response from 195.226.104.220 (
195.226.104.220 )
195.226.104.220 ip400-XX-XX-XX<00>
[dvl@cobalt ~ 3] $.
You can complete the definition of interface parameters using the web browser as
follows:
• Start your web browser and go to the address http://ipaddr.
• Start the configuration applet via the Config menu in the Gateway menu
(see section 3 “General information on configuration” from page 20). To do
this, you need to log on to the device. In the standard configuration, the user
name is admin and the password is ip400.
• You should change the user name and password immediately in the General
settings area under Change login parameters to prevent unauthorised
access (see section 8.1.2 “Defining the user administrator and -password”
from page 110).
•UnderIP Interfaces / Ethernet Interface under DHCP, set the DHCP
Mode to “Client” (see section 4.1 “Configuration of the Ethernet interface”
from page 24).
• Save the configuration permanently, using the Save and Activate buttons,
(see section 3.2 “Checking and saving the configuration” from page 22).
Tip
The installation can be concluded, using your Web Browser or, using com-
mand lines with the help of Telnet. In this manual, we describe the procedure
using the Web Browser, which is usually the most convenient one, for com-
mon application scenarios.

Page 16 VoIP gateway IP400 version 5.01
2.2.4 Setting the IP-interface parameters without DHCP
You will have to set the IP interface parameters of the gateway yourself, if your
network does not have a DHCP server.
In addition, you have to deactivate the DHCP client built into the gateway and acti-
vate the built-in DHCP server. Both are done by pressing the Reset button briefly
after a cold restart.
For configuration, the gateway is first connected directly to your computer.
• If your computer is connected to the local network, disconnect it from the
network for the duration of the initial configuration of the gateway.
... for experts
• If possible, configure your PC using DHCP!
• In the standard configuration, the gateway's DHCP server is only switched
on after a “reset”.
• Connect up the Ethernet connectors of the gateway and PC “back to back”
(sliding switch to “connect to PC”).
• If your PC has been configured via DHCP, then update the IP address using
winipcfg or ipconfig. Otherwise, set the IP address of the PC perma-
nently to 192.168.0.2.
• The gateway has the address 192.168.0.1.
Note
Ask your network administrator if you are not sure about which IP address
and subnet mask you can use for the gateway, as well as whether you are
able to use a default gateway, and if so, which one.
Caution
If the computer is connected to the network by a coaxial-cable (thin Ether-
net) Remove the BNC-T-piece from the Ethernet adapter. Make sure that the
network cable is not split in the process, as otherwise your network will no
longer work.
