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 the expansion chassis 
first and then the computer), then try the following troubleshooting 
steps: 

 

ƒ 

Verify that the required LEDs on the back of the chassis are lit. 
The most important indicators are the LINK LEDs that indicate a 
proper connection. All LINK LEDs should be ON if both PCIe 
slots are populated and both an uplink and a downlink iPass 
cable are connected properly. In the example shown below, we 
see all but the DNLIK LEDs are on indicating that the downlink 
cable is not connected, but otherwise all is functional. The ACT 
(activity) LEDs will light/blink only upon data transfers between 
host and expansion. They can be off so long as the required 
LINK LEDs remain on. 

                                    

 

 

ƒ  Also verify the Magma PCI Express Host card is properly 

inserted into the host computer slot. In case any other LED is off, 
ensure the respective card is functional and properly seated in its 
ExpressBox slot.      

ƒ 

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

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

above steps, go to
