\subsection{Mandatory setup - Hardware}
An EIGER single module (500~kpixels) needs:
\begin{itemize}
\item A chilled (water+alcohol) at approximately 21~$^{\circ}$C, which needs to dissipate 85~W.
\item A chilled (water+alcohol) at approximately 21~$^{\circ}$C, which needs to dissipate 85~W. For the (M, a special cooling liquid is required: 2/3 deionized water and 1/3 ESA Type 48.
\item A power supply (12~V, 8~A). For the 9~M, a special cpu is give to remotely switch on and off the detector: see section~\ref{bchip100}.
\item 2$\times$1~Gb/s Ethernet connectors to control the detector and, optionally, receive data at low rate. A DHCP server that gives IPs to the 1~Gb/s connectors of the detector is needed. Note that flow control has to be enabled on the switch you are using.
\item 2$\times$10~Gb/s transceivers to optionally, receive data at high rate.

A watchdog is running on bchip100 to check for the flow and temparature. If outside of parameters, the detector will be switched off.
Here is an explanation of the LED color scheme of teh bchip100:
\begin{itemize}
\item NO LED Main Power off or Blackfin not ready, yet.
\item RED Too high temperature or too less water flow
Detector is shutted down and locked.
Detector will be unlocked (YELLOW) automatically when conditions are good again.
\item YELLOW Detector is off and unlocked. Ready to be turned on.
\item GREEN Detector is on
