Raptor-Epsilon

Overview

Self contained Ethernet switch system in rugged enclosure

The rugged Raptor-Epsilon Ethernet switch system is packed with desirable features that provide enhanced performance and reliability. Layer 2+ switch capabilities provides advanced features such as VLAN, aggregation, jumbo frame support, programmable multi-layer classifier with 8 QoS queues per port, DSCP remarking for IPv4 and IPv6 frames, and multicast/broadcast storm control/flooding control. Automatic power savings intelligence powers down used ports and dynamically adjusts the power output on each active port based on cable length.

The standard system configuration includes MIL D38999 connectors with four 8-wire Gigabit ports per connector and one power connector. The serial port is available on the first Ethernet connector. The two optional SFP ports are provided on one additional connector for each port. Custom cable configurations, enclosure modifications, and coatings are also available.

Raptor-Epsilon system can be used standalone, without any connection to a single board computer, or in conjunction with a host CPU. The system'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 system's on-board management microcontroller and a host processor for out-of-band management. The 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 is provided through the wide-range +5-32VDC power supply, enabling operation using industrial power sources. 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.

Raptor-Epsilon's advanced Ethernet switch 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. The system 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.
