Network Redundancy
“Network Redundancy” is a functionality than can be enabled on Z-PASS devices when a 3G modem is
available (always true for Z-PASS2, true for Z-PASS1 when connected to Seneca Z-MODEM-3G modem).
This functionality is aimed at switching the network interface used to access the Internet from the Ethernet
(“primary” interface) to the Mobile/3G (“secondary” interface), when Internet access through the primary
interface becomes unavailable; when access through the primary interface become available again, the
network interface is switched back to Ethernet.
The parameters provided to configure Network Redundancy are explained in paragraph 18.2 “Network and
Services”.

Four levels of security can be configured to disable remote connection, providing increasing security levels:
