The 89EBPES32x8G2 Evaluation Board (also referred to as EB32x8G2) provides an evaluation platform for the PES32T8G2 and PES32H8G2 switches. It is also a cost effective way to add PCIe ports (slots) to an existing system with a limited number of PCIe ports/slots. The EB32x8G2 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 EB32x8G2 is a vehicle to test and evaluate the functionality of the PES32x8G2 switch. Customers can use this board to get a headstart on software development prior to the arrival of their own hardware. The EB32x8G2 is also used by Renesas to reproduce system-level hardware or software issues reported by customers.
