connected correctly.
2. Verify that the required LEDs on the back of the Target and Host cards are lit. Check CBL and EDG LED indicators, when ON it
indicates a a good link between host and target. All LINK LEDs on the host and target cards should be solid green and slot LINK LEDs
should be illuminated (depending on Gen speed of the card).
3. Verify the Target card in the correct designated slot and the Host card are properly inserted into the host computer x 16 slot. Make
sure the SW1 Dipswitch settings on both interface cards are set correctly.

Try moving the Host card to a different PCIe slot (if a slot is available).

Try another host computer.

If the expansion system is still not visible after trying all of the above steps, try replacing the Link cables, and both interface
cards.
