5. basic PCI Express link consists of dual unidirectional differential links implemented as a transmit pair and a receive pair The signaling rate for PCI Express Gen2 is 5 0 Gigabits second Lane direction A link supports at least one lane The PCI Express link at the PCle2 437 card edge is a sixteen lane x16 link The PCIe2 437 provides three slots with x8 connectors slots J1 J2 J3 and one slot with a x16 connector slot J4 slots are four lane x4 links slots can accommodate single lane x1 x4 or x8 add in cards Additionally slots J1 J2 and J4 will accept x16 add in cards Although not expressly permitted by the PCI Express Specification slots JI and J2 accommodate down shifting a x16 card into a x8 slot Plugging a smaller link card into a larger link connector is fully allowed The system is ready to be turned on once the PCIe2 437 is installed into the host PC either directly or with flex cable the power cable is connected to the PCIe2 437 and any desired add in cards are installed again either directly or with flex cable When the host is turned on 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 LEDs on the PCIe2 437 that provide a visual indication of link status A deta
6. iled 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 host to the PCIe2 437 slots are created with a PCI Express Switch Each link looks like a PCI to PCI bridge to the Host s BIOS The number of bridges can add up quickly Older BIOS may not have the resources to enumerate 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 PCle2 437 User s Manual 2 1 Revision 1 0 December 2010 CYCLONE Microsystems 3 1 CHAPTER 3 BOARD OPERATION SLOT CAPABILITIES The PCIe2 437 Four Slot Riser Card host interface is a x16 Gen2 card edge capable of 80Gbit s bi directional traffic The 2 437 can plug directly into a host PCIe slot or can be attached with up to 12 inches of flex cable Slots J1 and J2 have x4 Gen2 interfaces capable of 20Gb s bi directional traffic The slot connectors at J1 and J2 are down pluggable they have an open back edge that permits a x16 add in card to be installed Add in cards can be installed directly into the J1 and J2 connectors or can be attached with up to 12 inches of flex cable Slot J3 also has a x4 Gen2 inte
