The aTCA-6891 features dual-10Gigabit Ethernet (10 GbE) links, powered by Intel® 82598 PCI-E® 10 Gigabit Ethernet controller, routed to backplane Zone 2 connector to support PICMG® 3.1 option 1/9 connectivity. The 10GbE ports, also known as XAUI, support 10GBASE-KX4 and 1000BASE-KX as in IEEE 802.3ap. Therefore the aTCA-6891 is the key element to form the 10 GbE ATCA system with 10 GbE switch blade to provide a complete 10 GbE interconnect solution to the industry.

The dual-Intel® 64-bit LV-Xeon® processors and the up to 16 GB dual-channel PC3200 DDR2 REG/ECC memory provide aTCA-6891 unlimited computing power to accomplish any critical mission.

Various I/O features, includes VGA output, USB v2.0 ports, and serial console are available for front access. A PCI™/PCI-X™ 64- bit/133 MHz capable PMC site is designed for further function expansion. A SATA RAID 0/1 enabled RTM interface is also reserved.
