Diamond Rugged Layer 2 Managed 8-Port Gigabit Ethernet Switch sealed alum -40 to +85OC operating temperature
Epsilon is a managed Layer 2+ Ethernet switch module offering eight 10/100/1000Mbps copper twisted pair ports on a PC/104 form-factor board.
Epsilon can be used standalone, without any connection to a single board computer, or in conjunction with a host CPU. The module’s built-in microcontroller handles configuration and management. On-board memory holds dual application images, boot code, MAC addresses, and other parameters, and can also be used for program execution.
An RS-232 serial port enables communication between the module’s on-board management microcontroller and a host processor for out-of-band management. Epsilon’s built-in microcontroller is also accessible via a web management interface over one of the Ethernet ports. This port is then shared for simultaneous web management and normal usage.
Input power can be provided through the built-in, wide-range +7-36VDC power supply, enabling operation using industrial power sources. Alternatively, Epsilon can be powered from a +5VDC source.
To support the temperature extremes of fixed and mobile applications in both indoor and outdoor environments, the module supports fanless operation over -40°C to +85°C.
Epsilon’s advanced Ethernet switch board 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.
As a special order option, Epsilon can be built with a full PC/104 stackthrough bus interface, allowing it to be integrated into any PC/104 stack. However, the module does not interface to the PC/104 bus and does not require the bus for its operation.
Epsilon is loaded with all required firmware, enabling its immediate operation without any development effort. The included web interface provides an intuitive GUI for use in configuring and managing switch functionality.
