Tabletop issue in TP3106

Customer reported that one of the tabletops is not working - IP is not pingable and disconnected from the host manager 

host manager version is v100r002c00spc800 and the tabletop version is v100r001c01spc200

I have checked first the version compatability and found that they can connect to each other 

I have checked the network settings between the host and the tabletop and found that the left is working  but the center and teh right is not working , as the right is connected to the center one , i have asked the customer to check the connect with the DIP switch  as per below snapshot 

Then asked him to connect to it via console cable , but when he connect to it he got the below issue :

Then i asked him to try to boot it from network as per below steps :

But all of these steps failed , then i asked him to use the upgrade tool to put the software version again on it using upgrade from bootrom system 

After that the tabletop worked fine and we can open it normally
