  At XFEL it is planned to install most electronic components and computers for LLRF, diagnostics and controls inside the tunnel. Access to these devices during the XFEL operation will not be possible. Remote control and monitoring of all relevant parameters of the shelfs/crates and the computers must be ensured and should be done in a standardised way. In addition software downloads and debugging up to the FPGA level should be provided, even if an operating system crashes e.g. due to radiation, maintenance functionality must be available. An introduction to xTCA will be given, the reasons to change the crate standard from a VME to a xTCA based system and the experience with this new electronics standard will be described.
