+\subsection{Beam Time Preparations}
+For a beam time, please be aware, that everything can happen! Any sorts of non
+experienced failures happen according to Murphy always when you really don't
+need them :-)...
+So, please don't go to a beam time with {\bf one} TRB3 and no replacement module and
+always be sure that you have a Lattice Download Cable available to reflash the
+TRB3 if something goes wrong in the fever of a beam time.

 \subsection{Board Identification}
 \label{Trb3BoardID}
 The TRB3 boards are equipped with 5 temperature sensors, one for each FPGA. They contain a unique ID that is used to identify each FPGA. Additionally, the peripheral FPGAs have to bits identification (endpoint ID) corresponding to their position on the board.
