The ATC104 is a AdvancedTCA carrier that provides eight half-height AMC slots that can accept any AMC.1 or AMC.2. In addition slot B4 and slot B3 also have their AMC.3 routed together.
The ATC104 can be connected via PCIe up/down stream port to other server blades or additional carriers such as the ATC103/ATC104/ATC105/ATC106/ATC107/ATC108 or ATC109. The ATC104 can be utilized in distributed as well as non-distributed applications. Any of the ATC104 slots can be used as the upstream port for a PrAMC (Processor AMC, as the root complex). If the root complex is not a PrAMC, the ATC104 could use an external blade as its root complex. The ATC104 supports Non-Transparent mode on any of its AMC slots. This feature allows two root complexes to coexist in the same system. In addition, the ATC104 has a managed layer two switch. Seven of the AMC slots have dual GbE connections to this switch.
