These LEDs are located on the top side or component side of the PCB Each LED corresponds to one lane of that particular link One bank is labeled UP LN 0 upstream and the other bank is labeled DWN LN 0 downstream The eight upstream LEDs give the state of the link from the PC host that the PCIe 408 is installed into to the PCIe 408 If the PCIe 408 is installed into a x8 of x16 slot then all eight of the upstream LEDs should be on Since the PCIe 408 upstream port is an x8 link only eight lanes of a x16 slot will be used If less than the eight LEDs are on there is a problem with the link between the PC host and the PCle 408 If the PCIe 408 is installed into a x4 PCIe slot down shifting then only the first four LEDs will be on and the link is trained at x4 If none of the upstream LEDs are on turn off the host PC and make sure that the PCIe 408 is properly seated into the PCIe connector The eight downstream LEDs indicate the status of the link connecting the PCIe 408 to the PCIe 414 via the PCI Express cable If the PCIe 408 is installed into an x8 or a x16 slot and the eight upstream LEDs are on the PCIe 408 is connected via the PCIe cable to the PCIe 414 all eight of the downstream LEDs should be on If the PCIe 408 is installed into a x4 slot there still should be all eight downstream LEDs on If less than eight LEDs are on check to make sure that the cable is properly connected to each board 600 2704 PCI Express Fxpans
