3. PCIe403 the chassis is plugged into an AC power outlet and any desired add in cards are installed the system is ready to be turned on A number of things happen at this point First the PCI Express links are initialized This is a purely hardware initialization where each PCI Express link is set up following a negotiation of lane widths by the two ends of each link No firmware or operating system software is involved Once the links are initialized or trained there are LED indicators on each of three Cyclone Microsystems cards that indicate both the links that are trained and the individual lanes A detailed explanation of the LEDs follows later in this manual One essential requirement for system initialization is the ability of the Host system s BIOS to be able to enumerate the many bridges inherent in a complex PCI Express design The links from the PCIe 409 through PCIe 403 to the PCIe 412 are created with PCI Express Switches Each link looks like PCI to PCI bridge to the Host s BIOS The number of bridges can add up quickly Older BIOS may not have the ability to handle the number of bridges Make sure that the BIOS on the host computer has the latest updated BIOS If required contact the host system s manufacturer to make sure that the BIOS used can handle the large number of bridges that it will see in the system 600 2702 PCI Express FXpansion System User s Manual 2 1 Revision 1 0 February 2008 Zi CYCLONE Micro
