Magma PCI Expansion System User Manual

 

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: 

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

PCI Express slot and is inserted correctly.  

ƒ 

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

ƒ  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.  

 

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).
