We've run into a problem with our attempts to get the LCS control back up and running.
As reported previously, the Dolphin fiber connection between c1lsc and c1sus appears to be dead. Since we have no replacement fiber, the solution was to move the c1lsc machine in to the 1X4 rack, which would allow us to use one of the many available short Dolphin cables, and then use a long fiber PCIe extension cable to connect c1lsc to it's IO chassis. However, the long PCIe extension cable we got from Downs does not appear to be working with our setup. We tested the cable with c1sus, and it does not seem to work.
We've run out of options today. Tomorrow we're going to head back to Downs to see if we can find a cable that at least works with the test-stand setup they have there.
