My Computer Can’t Find the PCIe 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 the expansion chassis first and then the computer), then try the following troubleshooting steps:
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.
UPLINK
NO DOWNLINK
SLOT 1
SLOT 2
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.
Try moving the PCIe host card to a different PCIe slot.
If the expansion system is still not visible after trying all of the above steps, go to Chapter 6 to get additional help.
