For operation all slots need to be equipped with a module, or covered with
a blanking plate. Modules with a CI-slot need to carry the supplied covers,
even without CA-module. This is necessary to assure proper air flow for
cooling.
In case of a short circuit or an overload of the power supply, the system
reboots permanently (hiccup mode). The front LEDs of the modules and the
display of the handset start to flash. After elimination of the malfunction
the power supply switches back to the normal mode.
