Highly Advanced Gigabit Ethernet Switch

MRRS-8000G is an 8-port Gigabit Ethernet switch implemented in the compact PC/104 form factor. MRRS-8000G can be used standalone without any connection to a single board computer, or in conjunction with a host CPU.

Layer 2+ Managed Switch

MRRS-8000G’s advanced Ethernet switch chip includes a built-in microcontroller for configuration and management. It can be accessed either out-of-band, through the on-board RS- 232 port, or via one of the Ethernet ports.

Wide Input DC/DC Power Supply

Input power can be provided through the built-in, wide-range +7-36VDC power supply, enabling operation using industrial power sources. Alternatively, MRRS-8000G can be powered from a +5VDC source.

Rugged Design

Extended temperature operation of -40°C to +85°C is tested and guaranteed. MRRS-8000G was designed with harsh applications in mind

Innovative Power Management

MRRS-8000G’s advanced Ethernet switch controller includes two innovative features that enable automatic power savings. The switch can detect unused Ethernet ports on network devices and power them down or place them in stand-by mode. Additionally, the switch actively adjusts the power level needed based on cable length, saving energy on links shorter than the 100m maximum specified length.

Software Support

MRRS-8000G is loaded with all required fi rmware, enabling its immediate operation without any development effort. The included web interface provides an intuitive GUI for use in configuring and managing switch functionality.
