Better availability through standby router
If necessary, a standby router may be activated through the LAN interface that is
switchable via the input IN2. For reasons of availability, it may be required to equip a
second router (standby router) with a SIM card of another provider. The standby router
should only engage with the LAN, if the standard router looses the connection to the
GPRS network.

Device configuration:
• Standard and standby router: Configure an identical IP address (example:
192.168.1.1) and sub network mask (example: 255.255.255.0)
• Standard router: Activate LAN connection controlled via IN2
• Standard router: Activate interval for connection test (see Chapter 5.5.3)
• Standby router: Activate an LAN connection controlled via IN2
The connection between OU1-NO and IN2 of the standard router guarantees that the
LAN interface of the router is always active when the router is logged into the GPRS net-
work. If the connection should for some reason not be established, OUT1 switches to NC.
This will trigger the IN2 of the standby router. The standby router will then activate its
LAN interface.
As soon as the standard router has re-established the connection to the GPRS network,
OUT1 will switch back to NO. This will deactivate the LAN interface of the standby router
and the standard router will again assume the routing function in the network.

Note
Please note during the configuration that the network interface is inac-
tivated as soon as the function "Activate LAN connection via IN2" is
selected, and that no configuration will be possible any more. For this
reason, this setting should be the last step during the device configura-
tion.
The standby configuration assumes that both devices have the same IP
addressing. Please make sure during the configuration that only one
device at a time is in contact with the LAN. This will prevent IP address
conflicts.
