Q: Can I daisy chain ExpressBox 3T with more ExpressBox 3T?
A: Yes, but realize that aggregate bandwidth is limited to 10Gbps through the Thunderbolt port and PCI address and
IO space can be limited so the type of cards installed in the chassis may limit the number that can be daisy chained
successfully.
If a daisy chain device doesn’t work; check to see if a RED led (on the Magma Thunderbolt Card in the first slot of
ExpressBox 3T) is on. If so, the daisy chained device is drawing too much power and the current limiting has kicked
in and has turned off the power to the downstream device.
Q: Will ExpressBox 3T show up in Apple System Profiler or Windows Device Manager without any PCIe
cards installed?
Yes. In Apple System Profiler
