Must I reboot Windows after power-cycling the PXI?

[cdschmit]

The fans in the NI PXI-1042 are *noisy*!!! This thing is in a classroom and gets shut off everytime I turn around. Two questions: 1) is there any way to get around the reboot required to find the PXI cards on the PC every time it is power-cycled. 2) Where can I find quieter replacement fans for this thing?

Thanks,
Chris

Chris,

I am assuming you have a MXI connection from a PXI chassis to a desktop PC. If the PXI chassis is ever turned off, the only supported method to re-establish the connection is to power off both devices, power on the chassis, and then power on the PC.

The noisy fans, however, can probably be solved with the flip of a switch. There are two fan settings: Auto and High. This can be changed with a switch on the back of the chassis. I don't normally consider the 1042 disruptively loud unless the fans are on High. So, unless you need the extra cooling, setting the fan to Auto might solve both problems anyway. We also sell a 1042Q chassis... the Q stands for quiet. I hope this helps.

Chris,

I don't know what type of connection you have (MXI-3 or MXI-4)... I have had some success with the following method:

With everything up and running, go to Control Panel >> System >> Device Manager (Hardware Tab). From there, expand the "tree" for System Devices. There you will see 'PCI Standard PCI-to-PCI Bridge'. Right-click on that and choose 'Disable'. The PXI chassis can now be turned off. When you are ready to use the PXI boards again, simply turn the PXI chassis back on, and then choose 'Enable' from device manager and the chassis and computer will link up once again. So, it does require some action up front, but it will save you from rebooting

I can't guarantee this will work every time and I'm not sure if it works for MXI-3 (I have MXI-4) but it may be worth a try.
