My Computer Can’t Find the PCI Expansion System

If the expansion system is not visible in your Windows Device Manager

or your Apple System Profiler at all, you will need to turn off your

computer (first) and then the Magma expansion chassis (second) and

test all cords and cables to ensure you have everything connected

correctly. If everything seems to be connected correctly, and you are

sure you have applied power correctly (power up expansion chassis first

and then the computer), then try these additional troubleshooting steps:

 Double-check the PCI Express host card to ensure it is in a

PCI Express slot and is inserted correctly.

 Try moving the PCIe host card to a different PCIe slot.

 Check for a bad PCIe cable or connection. Put the x1 to x1

cable on the x3 to x3 connectors and the x3 to x3 cable on the

x1 to x1 connectors.

NOTE

The expansion chassis can function using only the x1 (1 lane)

connection. The second cable provides the additional x3 (3 lane)

connection. Combining the x1 cable and the x3 cable yields 4 lanes

(x4).

 If the expansion system is still not visible after trying all of the

above steps, go to
