The 89KTPES48H12G2 evaluation board (also referred to as EB48H12G2) provides an evaluation platform for the 89HPES48H12G2 switch. It is also a cost effective way to add PCIe ports (slots) to an existing system with limited number of PCIe ports/slots. The 89KTPES48H12G2 board is designed to function as an add-on card to be plugged into a x8 PCIe slot available on a motherboard hosting an appropriate root complex and microprocessor(s). The 89KTPES48H12G2 is a vehicle to test and evaluate the functionality of the PES48H12G2 switch. It is also designed to work with the 89HPES48H12 (Gen 1) switch. 

Customers can use this board to get a headstart on software development prior to the arrival of their own hardware. The 89KTPES48H12G2 evaluation boardis also used by IDT to reproduce system-level hardware or software issues reported by customers.
