Advantec focus on energy efficiency.

The industrial automation group of Advantech has introduced two energy-efficient unmanaged gigabit ethernet switches, the EKI-2725-BE and EKI-2728-BE. These new models feature an energy efficient design, resulting in 10 per cent to 15 per cent power savings as compared to previous models and similar models on the market. These new switches are designed with a variety of environmentally-responsible features, including RoHS compliance, optimised DC/DC power supply and a power-saving ethernet switch controller. During operation, power savings are realised on ethernet ports with no traffic, and ports not in use are powered-down for maximum power savings. In addition to gigabit (1,000 Mbps) operation, both the 5-port EKI-2725 and 8-port EKI-2728 support 9 K jumbo frames. This allows larger blocks of data to be sent with each transmission, for increased network throughput and reduced CPU utilisation of connected devices, which is important for emerging multimedia and video applications such as intelligent cameras employing the GigE Vision standard for machine vision. For applications requiring mixed speed devices, all ethernet ports support auto-negotiation for backwards compatibility with 10 Mbps and 100 Mbps devices and equipment. Also, with auto-MDI/MDI-X, there is no need for cross-over cables for inter-switch connections. The EKI-2725 and EKI-2728 feature an IP30 protected metal chassis and an operating temperature of -10 to 60A C. They are equipped with redundant +12 to 48VDC power inputs, plus 3,000 VDC surge protection on the power line, and 4000V ESD on the ethernet ports. Their compact size and flexible installation methods (including DIN-rail and panel-mount) allow installation in very space-constrained areas. Advantec was founded in 1983.
