Hi Bob,
From what it looks like, your chassis seems to be working at this point? The problems just exist with the 1120D module?
If your still having problems configuring the PXI-1010, I would use this article as a reference: Configuring a PXI-1010 or PXI-1011 Chassis in Measurement and Automation Explorer
If it is specific to the 1120D module, do you have a front panel connector connected to it, such as the SCXI-1327? Any additional detail about how the module is configured, any error codes, or any other information would help to identify the problem.
Regards,
