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.

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
