The ADLINK aTCA-9300 is a high performance AdvancedTCA® (ATCA) processor blade featuring dual 4-core Intel® Xeon® processor E3 1275V2 /1225V2, Intel® C216 Chipset, four channel memory up to 32 GB of DDR3 memory and 300 W power supply subsystem. Versatile connectivity includes dual 10GbE Fabric Interfaces, dual GbE Base Interfaces, quad front panel GbE egress ports, front panel dual COM and USB 2.0 ports and front panel VGA connector. An onboard SATA connector supports CFast up to 32 GB and the optional RTM (aTCA-R6270/R6280) supports an 8-channel mini-SAS port, dual 10GbE SFP+ ports, dual USB ports and dual hot-swappable SATA bays providing additional network throughput and storage capacities. The aTCA-9300’s thermal solution (including VRM heat sink) ensures stable operation under extreme operating environments and allows for compliance to the NEBS Level 3 standard (design only). The robust computing power and reliability of the aTCA-9300 meets the requirements of telecom equipment manufacturers (TEMs) and network equipment providers (NEPs), allowing them to build the next-generation telecom networks and communication infrastructures. Detailed features are outlined below and a functional block diagram is shown in the next section.
