The four ports of the integrated Gigabit Ethernet switch ensure maximum performance and are also energy- efficient as per IEEE 802.3az: If no data is transmitted over an interface, the power consumption shuts down automatically. Up to 3 ports can be switched as additional WAN ports with load balancing.
With its extensive VPN capabilities the device provides secure, high-performance connectivity to branch offices and remote workers.
