The Head Station is the primary element of ComBricks and has to be inserted in the most left slot of the fixed backplane socket. It schedules the interaction between all modules and provides data storage and an Ethernet interface for the user.
 
he Head Station provides power to all modules through its redundant power supply.

Type 1A contains a basic web server to inspect the status of the modules and customize the parameters of advanced modules. The ProfiTrace core is NOT enabled, but repeater modules can still be set to 4 networks.
