Network crashes when taking StackUnit 2 offline for repair

We have a Matrix x4 for core switch and over 160 enterasys A,B,C stackable switches in our network. I took off a 2nd Unit of a C2 switch, which is in redundant connection to the Matrix X4. After power off the Unit, the network crashes for 1 or 2 minutes. I think, there is an error in the configuration of spanning tree or other things. But I dont know, how to fix it. Is there anywhere a config to view, how it should be configured for the X4 and the A,B,C Switches?

I am very sorry you are feeling frustrated with this issue and I have sent your request into our GTAC group and you should be hearing from us shortly. Have you already logged a trouble ticket with our GTAC phone support?
Hi Tamera, thank you for your reply. I have not already logged a trouble ticket with your GTAC phone support. Is there any support in german language? Maybe there is a missconfigured switch or spanning tree configuration the reason for our problems. I am not really familiar with configuring switches and spanning tree .... In Netsight Console there are errors I cant interpret well. I would be glad, if there is someone who can help soon.
