How to fix connection problems

Your scenario is this:
You try to connect to your MicroTCA system but NATview does not succeed for some reason.

Have a look into the NATview documentation, section 13 "FAQs and Troubleshooting" for details.

I cannot connect to my Chassis. (Although I see it in the MCH Scanner.)

Check if your firewall blocks UDP port 623. If so then open this port.

My Chassis is not being Displayed. All I see is a Default Chassis

Follow these steps:
Open the FRU editor for FRU #253.
In the left window tree click on Board Info Area:
Check if the Board Manufacturer and the Board Product Name are not empty and contain something reasonable. Also check if the field Board Part Number contains something reasonable if it is not empty.
Click also on Product Info Area:
Check if the Product Manufacturer and the Product Name are not empty and contain something reasonable.
In the left window tree click on Board Info Area:
Check if the Board Manufacturer Name and the Board Product Name are not empty and contain something reasonable. Also check if the field Product Part Model Number contains something reasonable if it is not empty.
If the chassis has horizontally oriented AMc modules:
Open the Multi-Record Area, then goto OEM Record - MicroTCA Carrier Information Record. Check if the field Horizontal Carrier Orientation is false. If so you need to change it to true. Finally write the hanges to the FRU device.
