[Halld-controls] Hall D controls meeting on March 8, 2018

[Hovanes Egiyan]

Thanks Brian,

do you think it is better to switch to the new controller and see if the 
network port issue goes away?

If it does then we could keep the current controller with its network 
port issue as spare.

Hovanes.

One thing we found is that because the fans are slower than the original ones when the fan speed is set to auto the chassis thinks they're bad and faults. Since the speed is normally set to high this isn't an issue, so I disabled the switch on the back so it can only be set to high.

In addition, even when it is detected sometimes the PXI doesn't boot cleanly (it gets stuck in the initialization section of the code). Nothing a remote reboot didn't solve, but it is odd that this controller is still seemingly having network issues even with the new chassis.
