The EH3408 is an ideal, cost-effective switch for industrial networking where simple managing is required. As a lite-managed switch, it provides features you need, without the burden of those you don’t.

The device’s easy web configuration includes functions like SNMP, warning relay-out, Syslog and a user-friendly web GUI, which is especially useful when creating a compatible network for Industry 4.0 automation equipment, helping you set up Quality of Service (QoS) and VLAN to run industrial protocols like Profinet and Ethernet/IP. Furthermore, multiple account levels allow optimal management with different users accessing different operations.

All these features are packed in a slim, sturdy enclosure that fits in cabinets with limited space, while protecting against environmental hazards according to CE, FCC and UL standards. Two operation ranges are available for your choice: -10°C to +60°C for regular climates and -40°C to +75°C for extreme ones. Cyber protection is not overlooked either; the EH3408 series supports security features based on the IEC62443-4-2 standard.

An EH3408 switch comes with either USB or Micro-SD card support, so device configurations can be automatically backed up on a regular basis. In the unlikely event of device failure, simply transfer the USB or SD card to a new device to restore all original configurations.
