The EB-LOGAN-19 Evaluation Board provides an evaluation platform for the PES24NT24G2 switch and for other members of this switch family including PES16NT16G2 and PES12NT12G2.
The evaluation board, along with additional adapters and daughter boards provide by IDT, can be configured to test every possible combination of the number of lanes and ports offered by the switch. Advanced capabilities such as switch partitioning, NTB, DMA, and local port clocking can be evaluated with the evaluation board.   
The EB-LOGAN-23 brings out all 32 lanes of the device to 4 Mezzanine connectors located close to the device — one connector per stack of 8 lanes. Various types of daughter cards (provided by IDT) can then be plugged into these connectors to facilitate connectivity to one x8 or two x4 or four x2 or eight x1 link partners. Link partners may be plugged directly into these daughter cards, or they can be connected to these daughter cards via SAS or SATA cables and a different board with PCIe slots known as the 12-PACK board (provided by IDT). Given that the majority of the hosts/servers offer PCIe standard slots, IDT provides the necessary adapter cards that may be plugged into these host/server slots as well as the cables that connect such adapters to the daughter cards, which in turn are plugged into the main evaluation board on which the IDT PCIe switch device is populated.
