  • Page 9: General Information

    1. General Information The PLX PEX 8509RDK is a Rapid Development Kit based on the PEX 8509, a 8-lane, 8-port PCI Express switch. The PEX 8509RDK provides a complete hardware and software development platform to facilitate getting designs up and running quickly, lowering risk and reducing time-to-market. This RDK allows the upstream port of the PEX 8509 to be directly plugged into a system board’s x16/x8/x4 PCI...

    Auxiliary ATX Hard disk connector for supporting additional power requirements for add-in cards RDK Port Expansion An RDK Port Expansion Kit may be purchased separately, which will transform the PEX 8509RDK into a bench top platform that supports the full 8-port/8-lane configuration. When mated to the RDK Port Expander, the upstream port is connected to a PCI Express x1 Cable connector.
