[Sander, Jeff]

First we installed the H1A:PCIe Gen 2x1 Host Adapter into the front-end machine named Babbage.

lspci | grep "PCI bridge"

the above command shows devices connected via the host adapter.

We next installed the advantech ADC, DAC, and digitizer card (also a DAC) into the 4U expansion chassis. We can then see new devices on running lspci, but the digitizer card is still invisible, and we believe this is due to a missing driver.

Boot sequence:

power supply to expansion chassis

power on backplane board

power on front-end machine
