The cabinet can be accessed from 2 sides.

The front side is what is visible to the trainee. It is a typical ATC server arrangement. Trainees need to make use of the system control and monitoring software SkySMC to detect errors or system degradations before applying the right recovery strategy.

The rear side shows the manual hardware-based control panel. The teacher can manually enforce system degradations or errors.  He or she can e.g., switch off certain network connections, or hardware components by interrupting the power supply.

SkyRack includes a 19" touch-panel, accessible from the front side. This touch-panel can show varying troubleshooting screens.

The socket rack allows to do physical measurements on the system with oscilloscopes and multimeter. Various configurations of socket racks are possible (suitable for SUR, COM, NAV).

The server rack is equipped by default with 2 server modules. The modules contain databases and applications like the small pedagogical FDPS. The various applications communicate with eachother through the physical network. The applications provide typical ATC constellations in a nutshell.

The software applications include e.g.,

• NGINX - a commonly used is a web server that can also be used as a reverse proxy, load balancer, mail proxy and HTTP cache. The ATC environment includes a sample websites, its IP is 172.17.02.
  We can for instance refresh the website. Consequently the requests per second in the Nginx server will increase
• SNMP server - SNMP is widely used in network management for network monitoring. SNMP exposes management data in the form of variables on the managed systems organized in a management information base (MIB) which describe the system status and configuration. These variables can then be remotely queried (and, in some circumstances, manipulated) by managing applications. In the example it is a pure SNMP server. IP 172.17.03
• Pedagogical Flight Data Processing System (server) - it is a web service on IP 172.17.04. This pedagogical FDPS provides simulated data on arriving and departing flights. The events happen faster than in reality in order to see changes faster. 
• Distributed Control System (DCS) für fire monitoring. The server includes an DCS system for fire monitoring in gas or kerosine. The system can be connected to real Airport Rescue and Firefighting installations for training purposes or real ARFF training aircraft. Relevant monitoring data is passed to SkySMC.

The network routerboard consists of of a4-Port Ethernet Line Breaker with relay controlled Ethernet ports and integrated I/O module.  It is a is a cybersecurity system for industrial networks that can physically disconnect Ethernet connections. It features relay-controlled 10 Gigabit Ethernet ports, each of which can be turned on and off via a toggle switch on the device as well as remotely. Remote control is based on standardized communication protocols.
The teacher can cause network errors and degradation manually though physical switching or remotely through the teacher panel in the SkySMC.

The switchable power strip allows to manually switch on and off Servers and Facilities.
The teacher can cause network errors and degradation manually though physical switching or remotely through the teacher panel in the SkySMC.

The system is equipped with 2 Uninterrupted Power Supplies (min 3x750 W). Through SNMP, The SkySMC System Monitoring and Control software can monitor the USPs. 

From teacher panel, the teacher can switch on and off the USPs.

The system includes a Fan with Thermostat.

An important Facility in the ATC landscape is fire detection and monitoring. 

The server cabinet can be extended by a fire detector with SNMP communication to be monitored by SkySMC.
