12.6 System board fails to power UP A faulty 0SS board can cause the expansion system not to power UP properly. For troubleshooting, you can force power ON the OSS board by placing a jumper on J1 connector, see photos below. This will help you determine whether the board is functioning properly. You need the following items to perform this task.
Shutdown the system (computer and expansion unit). Disconnect the link cables. Remove the Target and Host cards. Check the target and host cards, make sure you have the correct model OSS-PCIe-HIB38-x16-F. Check the switch settings on the target card. Check the switch settings on the host card.
