Epsilon™ 8-Port Switch Managed 8-Port Gigabit Ethernet Switch Standalone PC/104™ module with wide voltage input and serial management port Key Features Eight 10/100/1000Mbps copper-twisted Ethernet ports with non-blocking wire-speed performance PC/104 form factor (3.55 x 3.775 in.) Highly Advanced Gigabit Ethernet Switch Epsilon is an 8-port Gigabit Ethernet switch implemented in the compact PC/104 form factor. Epsilon can be used standalone without any connection to a single board computer, or in conjunction with a host CPU. Layer 2+ Managed Switch Epsilon’s advanced Ethernet switch chip includes a built-in microcontroller for conguration 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, Epsilon can be powered from a +5VDC source. Rugged Design Extended temperature operation of -40°C to +85°C is tested and guaranteed. Epsilon was designed with harsh applications in mind. Latching connectors are used to further improve reliability. Innovative Power Management Epsilon’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 specied length. Built-in 8051 CPU for conguration management; RS-232 serial port provides out-of-band management interface Can operate autonomously or in conjunction with host SBC 176KB on-board frame buffer; jumbo frame support at all speeds 8K MAC addresses and 4K VLANs (IEEE 802.1Q), as well as 8K IP multicast group support Programmable multi-layer classier with 4 QoS classes DSCP remarking for IPv4 and IPv6 frames Rapid Spanning Tree Protocol Multicast and broadcast storm control, as well as ooding control Full-duplex ow control (IEEE 802.3X) and half-duplex backpressure, symmetric and asymmetric Flexible link aggregation support based on Layer-2 through Layer-4 information (IEEE802.3ad) Multiple protocol support: IEEE 802.1D, IEEE 802.1w, IEEE 802.1s, and IEEE 802.1X Extremely rugged temperature range of -40°C to +85°C with heat spreader or -40°C to +71°C with heat sink Software Support Epsilon is loaded with all required rmware, enabling its immediate operation without any development effort. The included web interface provides an intuitive GUI for use in conguring and managing switch functionality. www.diamondsystems.com | Diamond Systems Corporation | Mountain View, California USA | +1-650-810-2500
