PC/104 COM-1268
10-PortPC104+ Gb Ethernet switch, lightly managed
The COM-1268 is a rugged PC/104+ Gigabit Ethernet switch card equipped with ten (10) triple-speed 10/100/1000Mbps ports for connecting IPv4 and IPv6 compatible computing devices in demanding embedded systems LAN applications.
The COM-1268 is a rugged PC/104+ Gigabit Ethernet switch card equipped with ten (10) triple-speed 10/100/1000Mbps ports for connecting IPv4 and IPv6 compatible computing devices in demanding embedded systems LAN applications. This small form factor layer 2+ switch features an onboard microprocessor for local/remote control and monitoring, as well as roadmapped support for Quality of Service (QoS) traffic prioritization, Virtual Local-Area Network (VLAN) trunking, Simple Network Management (SNMP), and Rapid Spanning Tree (RSP) redundancy*.
Product Variants
Designed for robust performance under high shock/vibe and thermal conditions in space-constrained military / civil applications, the COM-1268 serves as an ideal Commercial-Off-the-Shelf (COTS) solution to enhance situational awareness and IP network centricity. The product is available as a standalone board or integrated into a military-hardened enclosed switch subsystem (DuraNET 1268), mobile router subsystem (DuraMAR 3230), or mission computer platform (DuraCOR 810-Duo). No additional processor is required to operate the board, and power can be drawn through either the ISA/PCI buses or 2-pin Molex connector (for non-PC104 systems).
Intefaces
The COM-1268 is designed with extended temperature components and comes with thermal heatsink plates to simplify systems integration and conductive cooling. A rugged, impedance-matched backplane-style connector brings out high-speed Gigabit Ethernet signals, along with an RS-232 serial console for CLI management, status LEDs, and zeroization. An out-of-band 10/100 Ethernet port is also available for Web GUI management of port settings. Up to four of the board’s switch ports can support fiber optic connections. If additional port density is desired, any of the GigE ports can serve as a link for cascading multiple switch modules, while an onboard infrared interface supports recognition and management of two stacked COM-1268 boards under the same console interface.
