Backup Netwo k Inte face
IPCorder KRR-416/424 supports the Backup Network Interface function. This service prevents disconnection from the network
in case of failure of one of network routes (both network adapters of the IPCorder must be connected). This can prevent
unavailability of the IPCorder in case of unwanted removal of a network cable or switch failure. To set up this service:
1) Connect the second network cable to your IPCorder (use network adapter number 2) and to the switch.
2) Go to the Nework tab in the web interface of the IPCorder:
• If Service mode is active – continue to the Network page and if needed set up the basic network settings.
• If Normal mode is active - go to the Settings menu in the upper part of screen, then select Configuration - Storage
and if needed set up the basic network settings.
3 Check the Enab e second network interface as backup option in the Backup Network Interface section.
4) Choose how the connection failure will be detected:
•Link (cab e connected) – this option detects disconnection of the network cable. If the cable from network adapter
no.1 is removed, the connection through the network adapter no.2 will be automatically activated and vice versa.
•Network (ping address from the ist) – this option checks if there is any traffic running through the active network
adapter of the IPCorder. If no network traffic is detected, the connection through the backup network adapter will be
automatically activated. Type at least one IP address of the independent server to the IP address ist text field.
5) In the Check Inte val text field, set the interval for checking availability of the connection, the default value is set to
100ms, the typed value is used for both types of failure detection.
6) Click the App y button to confirm the settings (use buttons App y Changes and Restart if Service mode is active).
Note: The Backup Network Interface function is active only in Normal mode. If you are using DHCP server to obtain an
IP address, it is possible that after the settings are confirmed, your IPCorder will temporarily obtain another IP address.
